titleForHeaderInSection wrong section count.
I have a fetch
let aFetchedResultsController = NSFetchedResultsController(fetchRequest:
fetchRequest, managedObjectContext: getManagedObjectContext(),
sectionNameKeyPath:"product.sectionKey", cacheName:nil)
In the following function:
func tableView(tableView: UITableView, titleForHeaderInSection section: Int)
-> String? {
print(section)
print (searchFetchedResultsController.sectionIndexTitles)
I see:
30
["1", "2", "4", "8", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K",
"L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]
Yes there are 30 elements but the array is zero based.
What is happening here?
Thanks
James

How to turn of the Journal logging of CoreData/Sqlite?
What is the magic combination of options to send to the sqlite to completely
turn off journaling.
I have an initialization on install that brings down a lot of data. I don’t
need journaling at this point
and it balloons the memory storage upon install to over 500MB!
I have tried:
var options = Dictionary()
options[NSMigratePersistentStoresAutomaticallyOption] = true
options[NSInferMappingModelAutomaticallyOption] = true
options[NSSQLitePragmasOption] = ["journal_mode" : "TRUNCATE”]
or
options[NSSQLitePragmasOption] = ["journal_mode" : “OFF"]
or
options[NSSQLitePragmasOption] = ["journal_mode" : “DELETE”]
and
options[NSSQLiteManualVacuumOption] = true
even
options[NSSQLitePragmasOption] = ["journal_size_limit" : "2”]
by :
do {
_ = try
self.managedObjectStore!.addSQLitePersistentStoreAtPath(storePath,
fromSeedDatabaseAtPath: nil, withConfiguration: nil, options: options)
} catch let error as NSError {
print("fail to add persistent store")
print(error)
}

Re: How to turn of the Journal logging of CoreData/Sqlite?
This is only at the install. The WAL file grows to over 500MB. Then when the app is restarted this WAL file is truncated and app goes down to about 35MB. I don’t know enough about sqlite and how it will handle the situation of when there is only 400MB left on the device. Basically I am using RestKIT bridged into my SWIFT application. This is using RestKIT api pretty straight out of the box stuff. > On Apr 6, 2016, at 10:27 AM, Jens Alfke wrote: > > >> On Apr 6, 2016, at 7:43 AM, James Cicenia > <mailto:ja...@jimijon.com>> wrote: >> >> What is the magic combination of options to send to the sqlite to completely >> turn off journaling. >> I have an initialization on install that brings down a lot of data.

Why doesn't my Swift method get called.
I added a swift file to my project. I wanted to use an open source sidebar. I have checked my targets, etc. Xcode compiles, builds and runs my code without a problem. But when I debug it, it just goes over and never into the method. Why would it do that? It builds and compiles, and even if I click the method it takes me to it so it is seeing it. Is there an Xcode setting I am missing? Thank you James ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Button Image Behavior
Hello -
I am trying to toggle a button with three states.
In IB I have it set to “off”
In the code I toggle as such:
func toggleStatus() {
if(product.favorite == false && product.avoid == false){
product.favorite = true
product.avoid = false
favoriteButton.setImage(UIImage(named: "Favorites-On"), forState:
.Normal)
}else if(product.favorite == true && product.avoid == false){
product.favorite = false
product.avoid = true
favoriteButton.setImage(UIImage(named: "Avoids-On"), forState:
.Normal)
}else {
product.favorite = false
product.avoid = false
favoriteButton.setImage(UIImage(named: "Favorites-Off"), forState:
.Normal)
}
}
When my screen comes up it is correctly in the off state.
When I touch it, it correctly goes to Favorites-On
When I touch it again, it correctly goes to Avoids-On
HOWEVER, when I next touch it, it briefly shows “Favorites-On” before going to
“Favorites-Off”
Why is it flashing like that?
Thanks

Moving from nib to code with custom controller.
Hello - I have always used IB before. I added my controller and linked it all up and it worked great. Now, I have to move this instead to code. I am confused on how to do this. 1) I have a custom view controller. (FeaturedViewController) 2) I have a UIScrollView (FeaturedScrollView) 3) I normally linked it up with IB scrollView = FeaturedViewController delegate = FeaturedViewController view = FeaturedViewController.

Predicates not fetching.
Hello - I first read an xml file upon startup into a Core Data sqlite. I then fetch all records... they are there. I then do a simple predicate @"name == %@", nameString If find nothing. And it is there. Now if I open the created SQLITE database via a client tool, It also turns up zero records. However if I do a like construct in SQL I can get it to return records. name like nameString% However, if I do a like via my predicate, still no records. I am using the same context throughout. My xml was dead simple as in: 8 Buddha There are no hidden characters, etc. Any thoughts?

ALAssetsLibrary and iOS5
Hello -
My code now for gathering images from the photo library seems to always timeout
the library instance.
How can I not? Nothing I have tried works.
I am using the ELCAlbumPickerController code which used to work great:
dispatch_async(dispatch_get_main_queue(), ^
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
// Group enumerator Block
void (^assetGroupEnumerator)( ALAssetsGroup *, BOOL *) =
^(ALAssetsGroup *group, BOOL *stop)
{
if (group == nil)
{
return;
}
[self.assetGroups addObject:group];
NSLog(@"count: %d", [group numberOfAssets]);
// Reload albums
[self performSelectorOnMainThread:@selector(reloadTableView)
withObject:nil waitUntilDone:YES];
};
// Group Enumerator Failure Block
void (^assetGroupEnumberatorFailure)(NSError *) = ^(NSError *error) {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Error"
message:[NSString stringWithFormat:@"Album Error: %@", [error description]]
delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
[alert release];
NSLog(@"A problem occured %@", [error description]);
};
NSMutableArray *tempArray = [[NSMutableArray alloc] init];
self.assetGroups = tempArray;
[tempArray release];
// Enumerate Albums
ALAssetsLibrary *library = [[ALAssetsLibrary alloc]init];
[library enumerateGroupsWithTypes:ALAssetsGroupAll
usingBlock:assetGroupEnumerator
failureBlock:assetGroupEnumberatorFailure];
[library release];
[pool release];
});
Anyone get this working properly?
Thanks

Core Data won't accept this string...
Hello -
I am trying to import data into Core Data. I am trying to set the value of one
the attributes to the following string:
MeasureID = 2376;
Property = {
root = {
ExtendedProperties = {
item = {
"@id" = PhotoRequired;
text = 0;
};
};
};
};
It takes the MeasureID but no matter what I do it won't take the String in
Property?
And worse, the following code: [self setValue:value forKey:attribute];
Just swallows it and doesn't throw any errors ?
Is the fact that it looks like an array or dictionary throwing off
NSManagedObject?
Banging my head,
James

Re: Core Data won't accept this string...
Thank you for taking the time to answer. Sorry about the declarative question
mark.
I guess I just needed a sanity check. I inherited a NSManagedObject category
that was being too aggressive
in converting everything to Dictionary. So, I turned that value back into an
NSString and it worked.
Thank you for your time.

Re: Newbie Question on a method signature
OK -
When I put the method ahead of the call it compiled and work.
So I decided to declare it in my header as:
- (UIColor *) returnUIForFont: (NSString *) theString;
Now the compiler complains:
/Users/jcicenia/Documents/iPhone/TOSPhone/ProjectViewController.m:142:
warning: incomplete implementation of class 'ProjectViewController'
/Users/jcicenia/Documents/iPhone/TOSPhone/ProjectViewController.m:142:
warning: method definition for '-returnUIForFont:' not found
What the heck is wrong with my declaration?
Thanks

You have to make sure your header has - (UIColor *)
returnUIColorForFont:(NSString *) theString in it so when you use
the method in other source files the compiler will know what the
arguments and return types to returnUIColorForFont: are. Without
this the compiler has to make assumptions and is warning you that it
is doing so.
Also, to compare if strings are equal you can just do:
if([theString isEqualToString:@"1"])
//do stuff

perfectly fine.

Newbie Memory Questions on a Code Fragment
Hello -
I am new to iphone and objective-c etc.
Here is some code I wrote for the appdelegate to initialize some
dictionaries and arrays:
My main question has to do with memory and releasing it. In my app I
will need listOfMonthNames for my popups
and will also need dictionaryOfProduceTypes to populate other
dependent popups.
thanks
James
-(void)initializeArraysAndDictionaries {
if(!listOfMonthNames){
NSArray *listOfMonthNamesTmp = [[NSArray alloc] initWithObjects:
@"January
",@"February
",@"March
",@"April
",@"May
",@"June
",@"July",@"August",@"September",@"October",@"November",@"December"];
// enumerate over items
printf( "static array\n" );
[listOfMonthNames
arrayByAddingObjectsFromArray:listOfMonthNames2];
// free memory
[listOfMonthNamesTmp release];
}
if(!dictionaryOfProduceTypes){
// Create a distinct dictionary of types that hold an array of
subtypes per type.
// Types and subtypes are attributes of the ProduceItem object
dictionaryOfProduceTypes = [[NSMutableDictionary alloc] init];
NSEnumerator *en = [produceItems objectEnumerator];
ProduceItem *item = nil;
while (item = [en nextObject]) {
if(![dictionaryOfProduceTypes objectForKey:item.type]){
//Doesn't exist yet, so allocate and initialize
[dictionaryOfProduceTypes takeValue:[[NSMutableArray alloc] init]
forKey:item.type];
}
NSMutableArray *subtypes = [dictionaryOfProduceTypes
objectForKey:item.type];
//Get the array then iterate through to see if we need to add a new
subtype to be added
NSEnumerator *en2 = [subtypes objectEnumerator];
NSString *subtype = nil;

First of all, you probably should just use the localized list of
month names that you can get through NSDateFormatter:
NSDateFormatter *aFormatter = [NSDateFormatter new];
NSArray *listOfMonthNames = [[aFormatter standaloneMonthSymbols]
retain];
This will give you an NSArray populated with NSString objects that
contain the localized month names in the proper order. Notice that
I retained the NSArray object. I did this because it is given to me
autoreleased so if I want to own it I need to retain it. When I no
longer need it I'll just call release on the object, this would most
likely be done in the dealloc method of the class in which I
initialized my object.
if(!dictionaryOfProduceTypes){
// Create a distinct dictionary of types that hold an array of
subtypes per type.
// Types and subtypes are attributes of the ProduceItem object
dictionaryOfProduceTypes = [[NSMutableDictionary alloc] init];
...
[dictionaryOfProduceTypes release];
}
By releasing the dictionaryOfProduceTypes object you are giving up
control of the object and allowing it to be deallocated. This means
that the object that you just initialized won't be around when you
need it. You want to only call release when you are 100% sure that
you won't need the object any more or when you are cleaning up, such
as in the dealloc method for a class.
NSMutableArray *subtypes = [dictionaryOfProduceTypes
objectForKey:item.type];
...
[subtypes release];
The objecForKey method returns an autoreleased NSArray. This means
that its retain count is greater than zero for now, but it will be
decremented to zero at some point in the future. By calling release
on this object you are causing it to be over-released and even worse
this will happen at some apparently random time in the future.
You should only call release on objects that you have created
through methods that begin with alloc, new, or copy or objects that
you have previously called retain upon. I suggest that you review
the Cocoa Memory Management Rules to understand this further:
<http://developer.apple.com/documentation/Cocoa/Conceptual/MemoryMgmt/Tasks/MemoryManagementRules.html

sqlite iphone question....
Hello -
I am trying to get my simulator to work with sqlite and was wondering
if I was missing some step?
Here is a snippet of code:
- (void)initializeDatabase {
NSMutableArray *items = [[NSMutableArray alloc] init];
self.produceItems = items;
[items release];
// The database is stored in the application bundle.
NSArray *paths =
NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory
stringByAppendingPathComponent:@"whatsfresh.sqlite"];
// Open the database. The database was prepared outside the
application.
if (sqlite3_open([path UTF8String], &database) == SQLITE_OK) {
NSLog(@"Open Database");
// Get the primary key for all produce.
const char *sql = "SELECT id FROM Item";
sqlite3_stmt *statement;
// Preparing a statement compiles the SQL query into a byte-
code program in the SQLite library.
// The third parameter is either the length of the SQL string
or -1 to read up to the first null terminator.
if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL)
== SQLITE_OK) {
NEVER GETS PAST THIS IF. I have queried the database and the data is
in there?!
Thanks

Working with files in the app bundle like this may be a non-no. At
least, it is for Mac OS X, and the emulator might have this issue.
To know for sure, put the database file into the "sandbox" and see
if it behaves better there.

Re: sqlite iphone question....
Hmmm,,,
OK I read the docs a bit.. and now I am confused. This code snippet
was basically copied and pasted from the sqlbook example.
It works when I run it in the simulator.
Mine .. .does get past the open database, but doesn't really get past
the select.
I also don't quite understand where I should set or copy
mydatabase.sqlite. It is in the Resource group and in the target
already.

IntefaceBuilder IPhone TableView Size Question
Hello - I am struggling a bit with learning Interface builder and am trying to design my view with the following structure: Top half, some pull down selectors. Bottom half the list of items matching the above selectors. I was now trying forever to resize the tableview when I drag it over to my window. But no matter what I can't seem to just shrink it and move it to the bottom half of my window. And the x and y boxes are grayed out no matter what I seem to do. Is this even possible? Am I missing a switch? Thanks James Cicenia ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Are you trying to resize the NSTableView? You should be working with the enclosing NSScrollView (which is easy to forget about, because the library shows a "table view," but what you drag out of it is a hierarchy rooted in a scroll view).

simple memory management question
Hello -
I have the following snippet:

[spvc setMyParentController:self];
[spvc setDialogView:fruitTypeView];
[spvc viewWillAppear:TRUE];
[fruitTypeView addSubview:spvc.view];
}
Now I thought I should put [spvc autorelease] at the end, but then my
view won't show.
Aren't I supposed to release spvc ? And if not, why not?

noobie mem management problem

Re: noobie mem management problem
Peter -
Thank you that does clear up a lot. And now it works beautifully on my
iphone in simulator mode.
However, when I ad-hoc it to my phone... it doesn't work. I get this
in my log:
11 Foundation 0x306cab10
_NSArrayRaiseInsertNilException + 48
12 Foundation 0x3066f8ec -[NSCFArray
insertObject:atIndex:] + 152
13 Foundation 0x3066f844 -[NSCFArray addObject:]
+ 30
14 WhatsFresh 0xc796 -[Sqlite executeQuery:]
(Sqlite.m:122)
15 WhatsFresh 0x4946 -[WhatsFreshAppDelegate
statesForItemAndMonthAndFresh:month:fresh:]
So is there something "different" that I have to do for the iphone
itself?
Thanks
James

Where is currentStates actually allocated?
Initially all ivars are set to nil (or 0 or whatever). So unless
you've set it somewhere, self.currentStates will return nil, and in
Objective C, you can send a message to nil and it is simply a NoOp
(ie, you wont get any error or exception).
currentStates needs to be allocated.
The next issue (and this is almost certainly where your problem is)
is that your @property is set to copy, so:
[self.currentStates addObject:@"hello"];
is equivalent:
[[self currentStates] addObject:@"hello"];
And [self currentStates] returns a copy of the NSMutableArray. And
so you create a copy, then you add the string, then it is
autoreleased.
So the issue is that the property specified "copy", which I don't
think actually makes sense for a NSMutableArray (besides
[NSMutableArray copy] actually returns an immutable NSArray (is
there any way to specify mutableCopy in an @property?)).
So you probably need to change the @property from copy to retain.
Alternatively, use the property without the setter/getter reference,
ie:
[currentStates addObject:@"hello"];
I hope that clears up more than it confuses,
Peter.

Re: Why doesn't this work on my device?
First off thank you for answering
Well unfortunately,,, this problem is more than in this bit of code.
Here is a snippet where the statesArray never gets filled. It works
great
in the simulator.
I think I am missing some key retain or such..
statesArray is synthesized and properly setup in my .h file with:
NSMutableArray *currentStates;
@property (nonatomic, copy) NSMutableArray *statesArray;
Now I have tried about four variations on this code and nothing seems
to make a difference.
Thanks

-stringByAppendingFormat might clean this up.

Re: Why doesn't this work on my device?
I understand. I read the docs on memory management. Thought I
understood it, fixed my code, etc.
Then I pushed it to the phone.
Maybe I need to sleep on this. Though it would have been nice if the
simulator really was a simulator.
I was so close, so excited, etc. and then bam! It doesn't work on my
phone.
Thanks for at least reassuring me that one day I will grok this memory
inside and out.

OK -- you need to step back and think this stuff through. In
particular, the above is a double retain and that you tried it with
and without indicates that you are taking wild stabs with a hope
that something works.
No worries and don't take it as an insult -- we all do this (you
should have seen the adventure I had with some header files
yesterday! "what if I just stick a semicolon HERE!" no... step
back... take a breath... think it through...").
Assuming that the above is executed and statesArray isn't
prematurely released (and set to nil or else you'd get a crash),
then your bug lies elsewhere.
You say it works in the simulator but not on the device?
I'd suggest stepping through whatever is supposed to fill the array
to make sure it is working as expected.

Re: Why doesn't this work on my device?
OK - Let me bother you one time more. I have found, the offending code, based upon log files etc. currentStates = [[NSMutableArray alloc] init]; self.currentStates = [self statesWithinMiles:currentMiles]; currentStates is not holding up in the device. It is somehow or somewhere getting released. I have searched the project and I am not releasing it anywhere. But, come the device, it loses itself. And then downstream methods that use this array bomb out. ? James On Feb 26, 2009, at 5:32 PM, Bill Bumgarner wrote: On Feb 26, 2009, at 3:29 PM, James Cicenia wrote: hmmm...

How do you set up the registration defaults in the first place? If you are using NSUserDefaults, you should be using -registerDefaults:. Now, if you are talking about loading a file manually, do you: - check to see if the file exists (NSFileManager's fileExistsAtPath:)? - check to see if reading the file worked (dictionaryWithContentsOfFile: returned something)? - check to see if it contains what you expect? b.bum ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

The Xcode debugger works as well on the phone as it does in the simulator. Which is to say that it is cantankerous, bizarre, difficult, error-prone, and unstable. But still an invaluable tool. Simply choose Run->Debug with your settings on "Device" and you'll be able to use the debugger on your device code, assuming the thing hasn't chosen to be broken at that moment.

Re: Why doesn't this work on my device?
It is a new morning. Same problem.
Here is my code:
NSArray *paths =
NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory
stringByAppendingPathComponent:@"whatsfresh.sql"];
int cntv = 0;
int cntf = 0;
ProduceItem *item=nil;
if (sqlite3_open([path UTF8String], &database) == SQLITE_OK) {
// Get the primary key for all books.
const char *sql = "SELECT type, subtype, name, id FROM
ProduceItem ORDER BY name";
sqlite3_stmt *statement;
if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL) ==
SQLITE_OK) {
It does get to the second If statement so it did find the database.
But then evidently it is not SQLITE_OK on my device in regards to that
last if.
These so simple things always take the most time. 1000s of lines of
code only to be stuck on this little database.
Thanks for all the help so far as I have eliminated some bad practices
and even cleaned up some memory leaks.
Now to just get this to work on my device.
Thanks

That'll most likely be because of the optimizer. If the compiler
determines that statement B after statement A has no impact on A and
would be faster to execute before A, it'll emit code that does
exactly that [very simplistic example].
Anyway, onto reading more about sqlite in the device itself. It

Did you make sure that the database is on the device where you
expect it and really there (say, again, via NSFileManager's
fileExistsAtPath:)?

Re: Why doesn't this work on my device?
Thanks for your patience. I did in fact use portions of sqlite books
and have the following code:
// Creates a writable copy of the bundled default database in the
application Documents directory.
- (void)createEditableCopyOfDatabaseIfNeeded {
// First, test for existence.
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths =
NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath = [documentsDirectory
stringByAppendingPathComponent:@"whatsfresh.sql"];
success = [fileManager fileExistsAtPath:writableDBPath];
if (success) return;
// The writable database does not exist, so copy the default to
the appropriate location.
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath]
stringByAppendingPathComponent:@"whatsfresh.sql"];
success = [fileManager copyItemAtPath:defaultDBPath
toPath:writableDBPath error:&error];
if (!success) {
NSAssert1(0, @"Failed to create writable database file with
message '%@'.", [error localizedDescription]);
}
}
when I debug it, it achieves success so it does exist.
Someone wrote:
if (sqlite3_open([path UTF8String], &database) == SQLITE_OK)
Don't use UTF8String to get a C string for a file system path, you
should use -fileSystemRepresentation.
I don't even know what that is?

But then evidently it is not SQLITE_OK on my device in regards to
that last if.
Have you checked to see if the file at path actually exists?
The documentation for sqlite3_open() indicates that it will quite
happily create a band new empty database if one doesn't exist at the
path.
Have a look at the SQLite Book List example (http://developer.apple.com/iphone/library/samplecode/SQLiteBooks/listing4.html
) as it demonstrates testing for the database file and then copying
it into the writable location, as necessary.

It is documented-- google, Xcode's documentation window, or

You can grab more error information by doing something like:
NSLog(@"Oops %s", sqlite3_errmsg(database));
If it says that the table doesn't exist then the database isn't
being correctly installed (or correctly initialized).

Seriously, you'll need to be more specific about what you're asking.
Do you mean you want to know *when* to release it? It's difficult to
say without more detail about what your intentions are in your
specific project.

OK -
The question is where do I release that object. If I put the release
at the end of the method, nothing will pop into my view.
If I don't release it, it works fine, but then I am worried about a
leak.
- (void)monthFruitAction:(id)sender{

The question is, will you be done with it within the scope of this
method? As a general rule, if you want to keep something around for
longer than that, you need to make it an instance variable instead
of a local variable. That way you'll be able to release it later.
Since you're using dot-syntax, I assume you're using Objective-C
2.0. So, declare a retained property, like this:
@property (retain) MonthPickerViewController *mpvc;
And, of course, synthesize the accessors for it:
@synthesize mpvc;
Now, since you've specified retain behavior for the accessors,
you'll need to autorelease the controller when you create it -
otherwise you'd over-retain it. Since it's no longer a local
variable, you'll need to use self.mpvc to access it:
- (void)monthFruitAction:(id)sender {
self.mpvc = [[[MonthPickerViewController alloc]
initWithNibName:@"MonthPicker" bundle:nil] autorelease];
[self.mpvc setMyParentController:self];
self.mpvc.view.frame = CGRectMake(19,66,260,258);
[fruitTypeView addSubview:self.mpvc.view];
}
Now, when all is said and done, and you're finished with mpvc, just
assign nil to it. With retain symantics for the synthesized accessor
methods, doing so should release the old value:
self.mpvc = nil;

Optimizing, uiview caching, and clearing that cached view.
Hello - I just noticed that my app's view controller is not clearing out the view and so if i make a selection somewhere else, the new data is being populated over the old data and showing up in the view. This could actually be good because it could increase the performance of my app... However, it seems that my app always will run the viewwillappear method. So I have two questions now. How do I skip over my populating code in ViewWillAppear to increase the response time of my app? How do I then clear the view when a new selection is made that should change the view?

I can't find the leak on this simple table view.
Hello -
I have a table view that I popup. However it is giving me leaks and
something about NSIndexPath is shown in leaks in instruments.
It is leaking upon showing the table view.
I have a mainview --> PopupView --> PopupView2
the PopupView2 is the one giving me the leak upon display.
here is the code:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"MilesCell_ID";
MilesCell *cell =(MilesCell *) [tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell =(MilesCell *) [[[MilesCell alloc]
initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath.row == 0){
[[cell numberImageView]setImage:image200];
}else if(indexPath.row==1){
[[cell numberImageView]setImage:image500];
}else if(indexPath.row==2){
[[cell numberImageView]setImage:image1000];
}else if(indexPath.row==3){
[[cell numberImageView]setImage:image1500];
}else if(indexPath.row==4){
[[cell numberImageView]setImage:image2000];
}else if(indexPath.row==5){
[[cell numberImageView]setImage:image2500];
}else if(indexPath.row==6){
[[cell numberImageView]setImage:image5000];
}else if(indexPath.row==7){
[[cell numberImageView]setImage:image1000];
}
return cell;
}
The Item cell inherits from another cell and doesn't override
anything. And that superclass cell doesn't leak.
So how do I track this kind of leak down?
Thanks

All my leaks are gone... but now a memory warning?!
Hello - I have dutifully tracked down every leak, except for that noted nsindex issue that is a red-herring. Otherwise I get none now with my instruments. However, when I debug on the device one of my screens is getting memory warning and after a few clicks freezes up my phone. I have dutifully followed: http://developer.apple.com/documentation/Cocoa/Conceptual/MemoryMgmt/Articles/mmNibObjects.html and put in my setview and deallocs of my outlets. However, this doesn't seem to cure the problem. What do I do next? I am very confused about this.

Re: All my leaks are gone... but now a memory warning?!
I see that on that one screen it does chew up memory after I select
and process. My other three screens all behave very nicely.
So, maybe it is the way I have architected this screen:
When I load the view it seems ok.
Then I popup a little view for the user to select a state:
- (void)stateAction:(id)sender{
self.spvc = [[StatePickViewController
alloc]initWithNibName:@"StatePicker" bundle:nil];
spvc.view.frame = CGRectMake(28,65,260,258);
[spvc setMyParentController:self];
[spvc setDialogView:fruitTypeView];
[spvc viewWillAppear:TRUE];
[fruitTypeView addSubview:spvc.view];
}
Then when they click the state from that view:
-(void)resetState{
[spvc.view removeFromSuperview];
[spvc release];
[self viewWillAppear:TRUE];<<<<<= IS THIS THE CULPRIT?
}
Do I need to release something?
Thanks

well how much memory is your app using? One of the performance tools
should be able to help you not just get rid of leaks, but tell you
how big your memory footprint is. Just because you're not leaking
objects doesn't mean you're not pooling them up somewhere on an
autorelease pool. If you use instruments or object alloc etc do you
see a rapidly climbing memory usage or huge numbers of allocated but
not yet freed objects? Are you making objects which uses masses of
memory?
The performance tools should be able to run against the simulator
and show how your memory footprint is changing.

I used this after opening sqlite:
// Modify cache size so we don't overload memory. 50 * 1.5kb
if (sqlite3_exec(database, "PRAGMA CACHE_SIZE=50;", NULL, NULL, NULL) !
= SQLITE_OK) {
NSAssert1(0, @"Error: failed to set cache size with message '%s'.",
sqlite3_errmsg(database));

View Caching Issues and Questions
Hello -
I am a bit confused on when or why a view is cached and what is the
best possible way to clear it.
First:
I have a UITabBarController. The views that this brings up are cached.
This is actually great as I can test to see if something is changed
and if so, do nothing and it brings up my view quick. So far so good.
However, when I issue a viewWillAppear it seems that instead of "re-
creating" my view it is actually overlaying my new image views on it
without the old ones going away. I have done something like:
NSEnumerator *itemEnum = [ [veggieScrollView subviews]
objectEnumerator];
UIView *tView;
while (tView = [itemEnum nextObject]) {
if([tView tag]==101)[tView removeFromSuperview];
}
And it clears those images but that seems rather poor to me and that
their must be a better and cleaner way.
Now I also have views that I popup from those parent views above and
they DON'T cache the view so they have to be reconstituted in their
viewWillAppear each time. This is bad because those popups have
content that never changes once the program loads.
So in their case, I want them to be cached.
Any help would be greatly appreciated.

NSString leak or RedHerring again?
Hello -
I do this a lot but only this give me leaks:
while (sqlite3_step(statement) == SQLITE_ROW) {
AvailableItem *newItem = [[AvailableItem alloc]init];
[newItem setName: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 0)]];
[newItem setType: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 1)]];
[newItem setSubtype: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 2)]];
[items addObject:newItem];
[newItem release];
}
My instruments tells me it is leaking NSString.
AvailableItem is a bare bones class with just synthesize and nothing
else.
Why is it leaking?
Thanks

Re: NSString leak or RedHerring again?
OK That worked but now that I got you:
Why is it complaining about the indicated array below:
while (sqlite3_step(statement) == SQLITE_ROW) {
//find subtype as key in the dict first
if(![aDict objectForKey: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 2)]]){
NSMutableArray *tmparray = [[NSMutableArray alloc]init]; <<<<<==
= Says it leaks?
[aDict setValue:tmparray forKey: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 2)]];
[tmparray release];
}
subtypeArray = [aDict objectForKey: [NSString stringWithUTF8String:
(char *)sqlite3_column_text(statement, 2)]];
[subtypeArray addObject: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 0)]];
[aDict setValue:subtypeArray forKey: [NSString stringWithUTF8String:
(char *)sqlite3_column_text(statement, 2)]];
}
Thanks again,

Need to use Quartz... I think?
Hello - I am painting my iPhone scrollable view which is nested in a parent view. I had originally been looping through and creating about a 1000 UIImageViews. This worked fine and dandy on the simulator but in real life, I think it is killing my little iPhone App. So will just drawing the images with Quartz be that much better? Well I figured I would try. But I am now confused on how I am supposed to make it work. In the quartz demo they have this: -(void)drawView:(QuartzView*)view inContext:(CGContextRef)context bounds:(CGRect)bounds But my scrollable view is created programatically. So what do I do in that case? Thanks James Cicenia ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Need to use Quartz... I think?
I am creating a visual indicator. There can be approximately up to 400 rows. Each row can have up to 24 little images. While in my instruments it never seems to get above 7MB on my device when a person selects enough parameters to actually display the rows it will eventually show up... say after about 8 secs. Then my app becomes unstable. Otherwise, if the parameter set is such that only about 40 rows show up, it works great non-stop throughout the app. I do want them to be able to scroll this list.

Quartz Demo does a little work to avoid creating a new view class for each demonstration (which may or may not be all that advantageous in hindsight). Either way, it is probably not really what you want in this case. What are you trying to do? If your trying to work with 1000 images, you almost certainly will not be able to work with them all in memory at once (and unless they are really tiny they won't all fit on screen at once, so having them all in memory at once is certainly a disadvantage). -- David Duncan Apple DTS Animation and Printing ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Unfortunately they are not sequential. They are a graphical calendar with two images per month. They can exist, they can be yellow or they can be green.

If the images are always displayed in the same order, then the simplest method might be something like this: Create a single image with all of your little images side by side in the correct order Create a UITableView For each UITableViewCell, embed a single opaque UIImageView. Assign the indicator UIImage as the content of that UIImageView Size the UIImageView to expose the number of indicators you desire and set its contentMode to UIViewContentModeLeft.

Re: Is UITableView more memory efficient than UIScrollView?
I have a listing of approximately 100 lines. Within each line I create a visual calendar that has up 24 images. These images are tiny. However, I have proved to myself that it is a memory issue and calling didRecieveMemory warning. This view has two tabs on top which allows you to switch between views. They are just a category for each with the same visual setup. When I switch the view, it displays, and then poof the app quits. I just can't seem to figure out what to do in that memory that will alleviate this problem. I have tried this: [veggieImageView release], veggieImageView = nil; [veggieTypeView release], veggieTypeView = nil; [veggieScrollView release], veggieScrollView = nil; but it just clears the view and then the same poof the app quits. I have aggressively tested everything else on this app and I am down to this one unstable area.

Why does releasing this array cause a crash?
Hello
I am confused on this one:
In my method I have a local array:
NSMutableArray *arraySubType = [[NSMutableArray alloc]init];
Then in a loop from the database I have:
while (sqlite3_step(statement) == SQLITE_ROW) {
if(![aDict objectForKey: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 1)]]){
NSMutableArray *tmpArray = [[NSMutableArray alloc]init];
[aDict setValue:tmpArray forKey: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 1)]];
[tmpArray release];
}
arraySubType = [aDict objectForKey: [NSString stringWithUTF8String:
(char *)sqlite3_column_text(statement, 1)]];
[arraySubType addObject: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 0)]]
[aDict setValue:arraySubType forKey: [NSString stringWithUTF8String:
(char *)sqlite3_column_text(statement, 1)]];
}
Shouldn't I now release arraySubType ??
If I do, later on I get a crash, if I don't I get no crash.
Thanks

OK, this array, you *should* release, yes.
Then in a loop from the database I have:
while (sqlite3_step(statement) == SQLITE_ROW) {
if(![aDict objectForKey: [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 1)]]){
NSMutableArray *tmpArray = [[NSMutableArray alloc]init];

[tmpArray release];
}
arraySubType = [aDict objectForKey: [NSString stringWithUTF8String:
(char *)sqlite3_column_text(statement, 1)]];
You have now just overwritten the previous value of arraySubType,
thus leaking it. You now have a handle to a completely different
object, which is autoreleased. This is why when you do release it,
you crash later.
If you do not use arraySubType between the alloc/init above and this
line, then you do not need to alloc/init it, just declare it only.

What is using up so much memory here?
Ok -
Here is the offending code that sucks up about 2MB:
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
while(thisState = [statesEnum nextObject]){
UIImageView *singleStateView = [[[UIImageView
alloc]initWithFrame:CGRectMake(2,0, 293, 184)]autorelease];
[singleStateView setImage: [UIImage imageNamed:[[@"wf-map-gray-"
stringByAppendingString:thisState
]stringByAppendingString:@"_glow.png"]]];
[singleStateView setTag:100];
[fruitStateView addSubview:singleStateView];
}
[pool release];
These are little pngs of the states. They are tiny 4KB images
yet when this loop runs it winds up taking up an additional 2MB

Compressed size does not matter. Your images (or at least your image
views) are 293x184, which means that each view is going to consume
293x184x4 (bytes per pixel) = 210.6K. I presume your looking at the
Memory Monitor tool, as the memory used by view backing stores is
not reflected in the memory usage as reported by the ObjectAlloc
tool, but assuming your PNGs are the same size as the view, that
210.6K number is far more indicative of memory usage than the
compressed size.

Re: What is using up so much memory here?
Well... easier said then done. How would one place irregular shapes of
the state over the map itself?
Any combination of states with a color needs to appear.
I was just overlaying the same square with just one state in the
square all lined up.

Re: What is using up so much memory here?
Ok -
I figured out what I can do. I can make a database of the x/y
coordinates after chopping down each state and then read the database
info to place the states.
Thanks for your hints and time.

Re: What is using up so much memory here?
Yes, I realized I would need a different approach. I got too used to web gif/png and just doing overlays. I have already told my designer to give me just bounded states with a spreadsheet of what he chopped off from the top and left. This will then be inputted into the spreadsheet then into sqlite. It should work a lot better. Thanks again for your input. James Cicenia On Mar 10, 2009, at 7:28 PM, Graham Cox wrote: On 11/03/2009, at 11:00 AM, James Cicenia wrote: Well... easier said then done. How would one place irregular shapes of the state over the map itself? Any combination of states with a color needs to appear. Since you are in a much-more memory-constrained environment, you need to get smart. Naively loading everything isn't going to work, so you need to figure this out. You have a map of the USA, I guess, and you can see part of it on screen at any one time (presumably scrolling to show different parts, or zooming in and out to show more or less). You can treat it as a bunch of tiled shapes, each having a bounding box. The bboxes will overlap a little in many places, but that's OK. All you need to do is build a data structure that associates the bboxes with the relevant images and graphics, then determine which bboxes intersect the visible screen area. For those that don't, you don't need to do anything. For those that do, you need to load the graphic elements, scale them as appropriate for your zoom (if need be - zoom is usually taken care of using the view's scale transform, but you may want to avoid caching a full-scale image if your zoom suggests you don't need it) and draw them. When you've done that, you can discard them again, or cache them for later. That's the basic M.O. If dynamically loading these images like this is too slow, you can then consider a way to cache what you loaded in such a way that when you become memory constrained, you can examine the cache and discard parts of it that you can't see right now, again by testing which bboxes intersect the screen. The same technique will work for zooming, because all you're doing is making the screen area that intersects your data smaller and bigger. If you cached a low-resolution graphic for a zoomed-out view, you can scale it while zooming is in progress to avoid an expensive re-load, then, if needed, reload a higher-res version at the end. Unfortunately you'll have to figure a scheme for doing all of this out for yourself, there isn't anything built-in because the need to do this is not all that generalisable. It's not that hard though. I would suggest though that using an entire subview for each overlaid image is going to hurt badly in terms of performance, scalability and ease of implementation. Instead just devise your own data structure that can hold objects having a bounding box (which sets the spatial location) and a reference to the image(s) it needs. Then when you draw, ask your data structure to draw all the cells that intersect the drawing area. For those that haven't loaded their images, they should now do so, then draw as usual. The overall data structure would have one object per state, but all it needs to maintain when not visible is the bbox. 50 rects is a far lower memory footprint than 50 full-sized images. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Help, I need a jedi memory master with time and patience to help me here.
Hello - I must be doing something conceptually wrong as this class will alway kill my app in the device without any console info. I am sure it is memory or retain related. In instruments my memory never goes above 5MB and then comes down a bit. In the device... it just quits after a few calls. If anyone has time, charity and patience and can help me spot what I am doing wrong, I would appreciate it. Just send me a response to me and I will send you the code. I have worked days on this. I have optimized my images. But something is wrong. One thing I did notice the retain count starts at 2 and ends at 2.

You could either use many CALayers or even a single large UIView(if you need user input events) or CALayer subclass where you render the images yourself. I presume there are only a small number of different images and you're using them over and over, right? If so, maybe it's better to subclass a view or layer such that you have your set of images loaded at init time and you simply draw them in the right place when you get the draw call. Then you don't have a large number of views or layers, you simply draw your images yourself when the time comes. Short of either drawing the images with primitives or pre-rendering larger chunks of the image, I'm not sure how to make it more efficient.
