a bug in iphone SDK's creation of view based xib files.

2009-09-01 Thread jon

a bug in iphone SDK's creation of view based xib files. (this is
using 3.1, but other's probably apply)

steps to reproduce.

step 1.

create a new iPhone View-based Application in Xcode.

step 2.

add a new Class.. "Cocoa Touch Class" of UIViewController subclass.

step 3.

be sure to include the "option" of "with XIB for user interface."

step 4.

open the newly created XIB file in interface Builder. (change the
view's back ground color to some color that you can see easily if
incorrectly placed in the iphone simulator)

step 5.

under the view size tab in the inspector of interface builder of this
newly created "view" in the XIB, you will find it impossible to
adjust the "stretch" arrows of the autoSizing.. .

so if you compile a working app that can be rotated in the iphone
simulator. (you will need a working app that can rotate the view in
the iphone simulator)

(and have the app's view in the simulator rotate automatically),
you will see that the view is no longer sized correctly (in the iphone
simulator). (you will see the background color in the wrong places)

the part that is wrong, and can be corrected:

inside the newly created XIB file, you will find a line "key="NSvFlags">256" (or something similar for the number)

this makes it impossible to change the autoSizing arrows to stretch
the "view" of the new xib in interface builder... (notice the first
xib file in the new project is set correctly, but this new xib you
create with tne new class is incorrect)

if you change it instead to ""274" then
you regain the function of being able to size your view in the
"autosize" area, and be able to rotate your view automatically in the
running app's iphone simulator.

this "key" should be changed so that you can change the stretching
ability to the programers preference, which is some other code that i
do not know at this time. the code given hard wires the auto stretch
permanently... the incorrect code turns off auto stretch
permanently but the correct code should make it the programers
option to have stretching or no stretching...

Jon.

Hi Joey,

On Sep 3, 2009, at 12:15 AM, Joey Hagedorn wrote:

Please do not discuss unreleased software on this list. You have  
access to the developer forums which are an appropriate place to  
discuss issues you may have. The issue you're discussing applies to  
iPhone OS 3.0 as well, so I'll continue to answer.


opps,  that should have said 3.0 only  (i did file a bug report,   
i should have also said i had filed a bug report  in the listing,   i  
only put it on the list, because i also mentioned a work around)



he springs and struts are disabled on views with simulated user  
interface attributes, so this is expected...In this case, it  
sounds like you expect the view provided in the UIViewController  
Subclass with XIB file template to have the autosizing parameters  
set differently.


if this were not a bug,   then why is the First XIB created (which is  
a UIView class also)  set differently than the Second XIB which is  
also the same Class??  ( I should have mentioned in the steps that  
this is not a UIViewController subclass,  that option should be left  
off to create a regular "UIView" Class...)and should provide  
exactly the same start point,  since they after all should be the  
same, yet they are not the same???
one has the struts/springs set differently than the other
worse,  disabled, so that no one can change them to be correct.


 on the first XIB,  the Simulated Status Bar is not disabled either  
in any case,  yet the size options (struts and springs) are set  
differently than the second XIB


(a second related thing is:)  setting the Simulated Status Bar to  
disabled,  does not actually disable the status bar,  (it does inside  
of IB,  but inside the iPhone simulator after it is compiled, it does  
not)  one has to also edit the XIB to actually turn off the Status  
bar??  (maybe  i am missing something there)


this can be verified by simply creating a new project of "View based"  
class,   then inside IB,   set status bar to "none" on the UIView  
XIB,   then compile and run in simulator,   the status bar is still  
there.  even if it is disabled on the main XIB too.  (unless i am  
confused about the option of disabling the status bar).



which brings up another question?  why does it matter that the status  
bar be there or not?   shouldn't you be able to adjust struts and  
springs no matter if it is there or not?   if one rotates the view,   
the status bar rotates in the iphone simulator,   shouldn't the view  
also rotate and adjust it's view appropriately?  right now that is not  
happening  shouldn't it for the second XIB view,  just like the  
first XIB view does correctly.  (even if the status bar is there, the  
first one is set correctly)


Thanks,
jon.

I realize after you just reminded me,  that i had said that wrong,   I  
did edit the plist file,  rather than the XIB file to disable the  
status bar.it would seem though, that setting the status bar to  
"none"  in IB should somehow make this change for you, so running it  
in the simulator,  you would get the expected behavior that is present  
in IB...   but I guess it just is not yet a perfect world.  I think  
version 7 of the SDK will become the perfect world :0)

website like ebay.com's flash content crashing webKit like app?

2009-09-06 Thread jon


can someone else confirm this on 10.5,  and then 10.6 system..

if you create a simple cocoa Application  (not document based,  
although that will exhibit same problem)


then in Interface builder put in a webView,  and then a textfield into  
the Window of the simple application project,  use textfield as an  
address field for the webview.


include the Webkit framework in the project.

in IB,  hook the textfield to the Webview address bar field.

compile,   and type into the textfield of the running app:   "http://www.google.com/ 
" which works fine...


but if you change that to:   "http://www.ebay.com/";   then the  
application crashes after a few seconds of loading..


I believe that the flash content of ebay is crashing the app?can  
someone confirm?   is this a known bug?   something wrong with flash?   
my system?

Are you saying that a version of this type of app is not crashing the  
Application  when you do this type of thing?   are you on snow  
leopard?  this simple app makes it through without exiting?  (using  
ebay.com?)


nothing too interesting about the console log,  here it is:   more  
like an abrupt exit...   nothing was spit out in the debugger as a  
crash.

The Debugger has exited due to signal 2 (SIGINT).The Debugger has

i have 10.5 and the latest version of Safari for leopard.   I am  
checking to see what version of flash this app would be running  
into... (not sure how to check that yet)

after installing flash again from Adobe,  to make sure it was the  
latest..(didn't help).   I realized that maybe the app needs to know  
about a "flash" type of framework or something like that?


is that type of thing needed?  possible?

I just unchecked it,  now it runs through without the crash.

so there is something in flash that is checked that shouldn't be  
checked?or just sort of normal  and i always have to uncheck that  
when ever using the webkit?

2009-09-06 Thread jon

thanks for the replys,  that helped alot,   (now i've got to figure  
out why the sample code that comes with xcode "MiniBrowser"  does not  
load flash at all  (if garbage collection is turned on,  no other  
changes)...


it must be something related...   i've already tried unchecking for  
that project,   but it still doesn't load the flash content,
(miniBrowser also never stopped at a "break point" kind of thing  
either though)


but you've gotten me closer i think.

thanks,
Jon.

Bug: CalendarStore framework adding events with alarms with email address.

2009-09-13 Thread jon

I will be making a bug report for this,  but this is here on the list  
to show that this can work,  if you ignore the result displayed in iCal.


If you have your address book filled out with your own card with your  
own email of for example "myem...@me.com",  not other emails in your  
card.


and then create a program with code like this that adds a calendar  
event in iCal like this with an alarm that has an email type of alarm  
event:


#import 
#import 
#import 

CalEvent *newEvent = [CalEvent event];
CalAlarm *alarm3 = [CalAlarm alarm];
NSError *err;
CalCalendar *AuctionAlarmCalendar = [CalCalendar calendar];

alarm3.action = CalAlarmActionEmail;
alarm3.emailAddress = @"mynewem...@me.com";
alarm3.relativeTrigger = -nuUnit3;
[newEvent addAlarm:alarm3];

	[[CalCalendarStore defaultCalendarStore] saveEvent:newEvent  
span:CalSpanThisEvent error:&err];



the iCal event will have a properly set up event with alarm,  but the  
email address will display "myem...@me.com".
the actual event alarm will correctly send an email to "mynewem...@me.com 
" though.  it will just have the wrong email displayed in the iCal  
event.. annoying, but atleast it will work.

I put this code in to retain after you said that,  but there was no  
change in the outcome,  still the array shows everything in order,   
except that the NSNumber comes out as garbage.
I checked node1 to see if it was well defined,  before and after  
putting it into the array,  and it is.

What does the code for -setTypeOfLeaf: look like?  If you're not  
retaining it in that method then it is getting (auto)released the  
next time the autorelease pool is drained.  Just because the array  
will automatically retain the node object doesn't mean the NSNumber  
inside that object will also be retained automatically.

Re: coding NSNumber in NSArray?

2009-09-14 Thread Jon

I don't quite understand why you don't see the word "NSNumber" in my  
code...   when you said twice incorrectly that it doesn't involve an  
NSNumber


nor why you don't see the word "NSArray" in my code.  when you said  
again incorrectly you don't see an array being used?


Nor why you don't believe it is the "REAL" code?

nor why you want me to use encoding for an NSNumber?

it is pretty obvious other people understand what they are looking at.

maybe you ought to look and see if you can see where those words are  
used, and how they are used...

getting accessor method info in a different class.

2009-09-18 Thread jon

In one class,  I have set webView up like this...  which works fine,   
but i want to have access to this pointer from another class...
i am not getting something correct here,  it gives me warning:   
"WebView may not respond to webView"

i'll just include the relevant code.

what am i not understanding about accessor methods?
what is the proper way to have access to the pointer of the webView  
but in a different class..


 the webviewcontroller class works as it should, (the .m file has the  
@synthesize in it)  but the bookmarkcontroller class returns the  
warning above. (some extra stuff is added like @class to see if it  
would help)

Jon.

header of class webviewcontroller:
-
#import 
#import 

@interface webViewController : NSDocument
{
IBOutlet WebView *webView;
}

@property(readwrite,retain) WebView *webView;

@end
-

header of class BookMarkController:
-
#import 
#import 
#import "webViewController.h"

@class WebView;

@interface BookMarkController : NSWindowController
{
WebView *theWebView;
}

@end
-

implementation of class BookMarkController:
-
#import "BookMarkController.h"

@implementation BookMarkController

- (void)setup
{
[theWebView webView];  // here i get the warning;
}

access to object from a different class

2009-09-18 Thread jon

Ok,  I did not get the desired result, but i am a little closer,  I'm  
going to set this up again.
below is example code to set up the circumstance,  so you better see  
what i want to do. (stripped down to what i am trying to find out)   
(webView is hooked up in IB to a WebView object)


 (i want to replace the  with something that would work where  
theWebView is pointing to the same thing as "webView" from the first  
class a pointer to the current WebView object)


In first class,  I have set webView up like this...  which works  
fine,  but i want to have access to this current webView object from a  
different class


how does one go about getting at the instance "webView" coding wize???

Jon.

Added info:

i would try this:   theWebView = [aController webView];except that  
the "aController" is new, and not pointing to the thing i want,  the  
first webView's pointer to it's object instance...

Preferencepanel.xib file with an extra delegate object place inside

2009-09-21 Thread jon

I've created a preference panel controller object and xib file which  
are normal,  except for the fact that i've also placed an extra object  
in the xib file.


the sole purpose of this extra custom controller object  (sole  
purpose of it being in this xib, it has a whole other life in it's own  
xib)///  is so that i can make this custom object the delegate of the  
PreferencePanelController by a single connectiong in IB
from the preference  panel controller delegate to this extra custom  
controller object,  (which i need to access one of it's methods)


the problem is that this custom controller object has an awakeFromNib  
method,for it's own window object.


so everytime i call the preference panel,  the awakeFromNib in the  
custom controller object is fired


hopefully some well heeled cocoa sailer captain here is going to tell  
me there is a way around this situation (other than "don't do that")   
where you'd think the engineers have thought about how you would go  
about connecting up delegates and just plain old methods   (like main  
menu submenu Preference,   being connected to a different file  
(different object  in that file) (the preference panel controller  
object)


hopefully i can create these "extra objects in Xib files"  all i want,  
and be-able to get around this action,  because I constantly need to  
fire off other panels and windows from say the

main menu,  or preference panel   is there a way??

thanks in advance,
Jon.

Use NSAppleScript or the scripting bridge. There's some sample code  
on ADC that will show you how to use the scripting bridge to send a

redrawing a particular subview in non mainWindows.

2009-09-27 Thread jon


I've got a Document type program,

the windows are structured like this:

Window -> ContentView -> SplitView -> two CustomViews -> one of them  
is Bordered Scroll view (outlineView) ->Outline View


i have one instance of Outline View  called myOutlineView,   so no  
matter how many documents are displayed on the screen,   there is only  
one myOutlineView instance,


the current "mainWindow"  updates the myOutlineView just fine when i  
make a change to this one instance,   but i want to "redraw" or update  
the Outline View of all the other open documents that can be seen so  
they also match (on screen) the one instance of myOutlineView.   in  
code they already do match.  so they just need "updated".


so far i can find the chain of windows,  like this,  but i can't  
figure out how to go deeper into them to be able to udpate the custom  
view down deep   maybe i'm approaching it wrong too...


any help would be great,(the setHidden is just there as a test,   
it is there so i know i've found the correct window, and eventually  
the correct subview)

thanks,
Jon.

IBOutlet NSOutlineView  *myOutlineView;
--


NSArray *theWindowsArray = [NSApp orderedWindows];
NSWindow *theWindow = [theWindowsArray objectAtIndex:1];

theContentView = [theWindow contentView];

//-  i need to find the split view of "theContentView"  and  
then the outline view of that one side of the split view -//


[theContentView setHidden:YES];

Re: redrawing a particular subview in non mainWindows.

2009-09-27 Thread jon

I am probably not describing it accurately,I'll try to understand  
and describe what is going on more accurately in a bit,   more likely,  
i have one set of data,   and each time a new window is open,  it is  
creating another instance of the outline view,   i have not found away  
to get at the old instances of this view...


thanks,
Jon.

Re: redrawing a particular subview in non mainWindows.

2009-09-27 Thread jon

ok,  after thinking and analyzing what was going on,  everytime i make  
a new document in the running app,   it created a new instance of the  
window and all related stuff in the window including myOutlineView.   
and then my dataSource in code remained the same that fills out these  
outline views...   (atleast this is my current understanding).


so my question now morphs into:

  as Jens says below,  he in some cases is looping through the apps  
window list...


in my case,   in my main document xib,  i have an "outline Controller"  
which is type NStreeController...  and i have this defined..


IBOutlet NSTreeController *treeController  which is the thing that is  
controlling the outline view,  and appears to be the thing i want to  
update...


the question it appears to me is:  that this "treeController" also is  
made into multiple instances with each new Document,   is there an  
already defined "loop" of these?  (a list of the open document's  
NSTreeController *treeController;)


or do i need to make an NSMutableArray,  and keep track of these  
myself?   and then update these instances myself by looping through  
them?


thanks,
Jon.

NSTextField, drawing the text offset to the right in the field

2009-09-28 Thread jon


i've got a textfield defined...

IBOutlet NSTextField *addressBar;

but i don't want to draw the text that is in the field right up  
against the left boarder of the bounding box of this defined field in  
IB,


I want to start the text like 20 pixels to the right of the left  
boarder  and still have the nicely defined frame of the field in it's  
original place...


so far i've tried various methods,   one of them is below

NSRect newFrame = [addressBar bounds];

newFrame.size.width -= 20;
newFrame.origin.x += 20;
[addressBar displayRect:newFrame];

but haven't had any success,  I'm sure someone here knows exactly what  
i'm trying to do and knows a quick way to do it..


i've also tried this:  thinking i could get a textview back into a  
textfield...  or somehow use a textcontainer on NSTextField... with no  
success...


[addressBar setTextContainerInset:theInset];


thanks,
Jon.

Re: NSTextField, drawing the text offset to the right in the field

2009-09-29 Thread jon


i've got something i think is close...

i've got a custom cell,  and a custom textfield,

i've got an override implementation of "drawInteriorWithFrame"  that i  
think will work.


but i'm confused as to where to call "drawInteriorWithFrame",   right  
now it is inside the custom Cell,   but the custom textfield never  
calls it as i believe it should?


right now
---
IBOutlet ImageTextField *addressBar;
---

[addressBar setStringValue:urlString];
is properly using my custom textfield,  but the custom textfield  
doesn't appear to be using the custom cell...  (or atleast the new  
drawInteriorWithFrame is not being called)


(i have not overriden the "setStringValue")  Maybe this isn't the  
right call, and it is bypassing "drawInteriorWithFrame"?


the only connection between custom textfield and the custom cell is

#import "ImageTextFieldCell.h"

 is inside the header of the custom textfield.

does there need to more connection to it?   or how would i get this  
call to the new drawInteriorWithFrame?


the running app shows the text field filled in properly (just not  
offset, as the override implementation of drawInteriorWithFrame would  
have done) ,   so it must have called the super of it somewhere.


thanks for the help in advance.
Jon.

how is the simpleBrowser example that is provided with xcode doing this?

[fsBrowser setCellClass: [FSBrowserCell class]];

fsBrowser is an instance,

IBOutlet NSBrowser*fsBrowser;

yet isn't setCellClass a class method?

No, it's a regular instance method; just look in NSBrowser.h:

- (void)setCellClass:(Class)factoryId;

hmmm,  well i'm trying hard to do it...here is what i've done...

in a header:

IBOutlet ImageTextField *addressBar;

i've created this pointer to this instance...

and then in the awakefromNib method,  i have this...

[ImageTextField setCellClass:[ImageTextFieldCell class]];

this set's the class so it's cell is "correct"... for the class...   
but


but maybe this is too late for the instance addressBar.  which was set  
in the header and IB???


I don't know how to check this instance to see if it is using the  
custom cell,   and i don't know how to set the instance  
specifically... (if this class method didn't do it)?

Then you have to *make* the custom textfield use the custom cell. :)  
Use

cover this sufficiently:

As the first part states, an instance of your cell class must *be*  
this text

field instance's cell. You have to make that happen... m.

+setCellClass: just tells the view "Hey next time you initialize
yourself, make a cell of this class."  Since your ImageTextField
instance was created inside of IB, this is never going to happen.
Instead you need to change the class of the cell from within IB, under
the Identity inspector.  It might be helpful to switch to the
hierarchical view so you can get easy access to the text field's cell.

IB webview oddity/question...

2009-10-01 Thread jon

if you make a new IB project,   create two new windows,   with a new  
webview located into each window,


if you go to one of the webviews,  and get the inspector up and go  
into the attributes,  and turn off everything,  like java,  plugins,  
animate images,  etc...


the second webview also turns all of it's attributes too?   if you  
turn one of them on,  they both turn on.


why are they linked?

possible bug in webView big and small load sizes...

2009-10-01 Thread jon

I did an experiment,  where i had a small window with a small webView  
in it...


and then a large window with a large webView in it,  in the same XIB  
file...   small was like 200 pxs   and the large one was nearly as  
large as the screen.


(actually i had the same window,  and ran a loop,  while the program  
was executing, i would simply drag the window to small, and then large  
size,  randomly and controled one execution of the loop per drag of  
the window,  to make sure,  i would do several smalls in a row,  and  
then several large in a row...  and then alternated for a while...)  i  
also have a timer to delay at my setting,  so that i am sure the page  
is completely loaded...


i loaded a complex search result  of Ebay.com web site into the  
webView,   Ebay has a lot of flash and Java, and lots of real Cr*P on  
in their search pages..  (this will only fail with an Ebay site or  
a site with lots of kludge,  not other sites)


after i load each view,   I  ask it for it's   DOM document


	DOMDocument *myDOMDocument = [[offScreeneBayWebView mainFrame]  
DOMDocument];


very consistently later in the class,  the small window ALWAYS fails  
to have a viable DOMDocument or atleast partially non viable..


while the large webView consistently always gives me all of the data

I'm wondering if this is a bug,  and if anyone has seen something like  
this before?



here is the code that consistently fails on the small window,  the  
"attValue"  consistently is "nil" in the small window,  and always  
correctly sets in the large window...
on exactly the same page load.. which is a very complicated search on  
a specific category of ebay.com


this looks like a bug to me...   but maybe someone knows what is going  
on here..


interestingly,  "thelength1"  is always correct,  on both the small  
and big windows...  i can't find any memory reason why this would fail  
on small and then fly on a big window... (looking for a memory problem  
in my program)...


Jon.


	DOMDocument *myDOMDocument = [[offScreeneBayWebView mainFrame]  
DOMDocument];
	DOMNodeList *allTableNodes = [myDOMDocument  
getElementsByTagName:@"table"];

NSUInteger thelength1 = [allTableNodes length];

DOMNode *node;
DOMNode *att;
NSString *attValue;
DOMNamedNodeMap *attributes;

for (i = 0; i < thelength1; ++i)
{
node = [allTableNodes item:i];
attributes = [node attributes];

att = [attributes item:0];
attValue = [att nodeValue];
if(attValue != nil)
{
isItInThere = [attValue rangeOfString:@"nol"];

			if (isItInThere.location != NSNotFound)   //-- this bothers  
me,  what is the non negative way of asking this if statement?

if (![attValue isEqualToString: @"cmpb nol"])  
{break;}
}

that sounds plausible,  there are more than one attributes...   I  
don't know the name of the element,  just that part of the name is  
"nol"  and that i don't want the one called "cmpb nol"...


which makes it difficult,   but you gave me something i can experiment  
with  to see if i can see that behavior happen,   thanks.

attr = [attributes getNamedItem:@"someName"];

adding a new window and controller to a Document project on startup...

2009-10-02 Thread Jon

On a standard Cocoa Document based project,   I want to add a new  
window object/instance on startup (similar to adding a preference  
panel, but a permanent offscreen window)


as an experiment,  i did this below with a new onScreen window:

i get the new window to load alright on start up,  but this disables  
the old Document class somehow?,  not even the old init is called  
anymore??...  I'm sure someone here can see quickly what i'm missing  
in this experiment process...

(or give me a quick lesson in how Cocoa document apps startup)


start with a new Document based cocoa project..

add this new window controller class,  also add a xib file that is  
nothing more than another window the same as the MyDocument.xib  
connect the new window to this new owner object



#import 

@interface MyDocument2 : NSWindowController
{
}
@end


#import "MyDocument2.h"

@implementation MyDocument2

- (id)init
{
self = [super initWithWindowNibName:@"MyDocument2"];
if (!self) { return nil;  }
[self showWindow:nil];
return self;
}

- (NSString *)windowNibName
{
return @"MyDocument2";
}

@end


in the main menu nib,  added a new "object" and make it the  
"MyDocument2" object.  so that this class loads on startup, and i get  
the window on startup.


in the old "MyDocument" class,  i changed this as an experiment, maybe  
this is closer.


#import 
#import "MyDocumentController.h"

@interface MyDocument : NSDocument
{
}
@end


/*- (NSString *)windowNibName
{
return @"MyDocument";
}*/

- (void)makeWindowControllers
{
	MyDocumentController *controller = [[MyDocumentController alloc]  
initWithWindowNibName:@"MyDocument"];

[self addWindowController:controller];
	[controller showWindow:nil];   //  trying different  
things in here..

}


and then I added this class as part of the experimenting...


#import 

@interface MyDocumentController : NSWindowController
{
}

@end

#import "MyDocumentController.h"

@implementation MyDocumentController

- (id)init
{
self = [super initWithWindowNibName:@"MyDocument"];
if (!self) { return nil;  }
[self showWindow:nil];
return self;
}

- (NSString *)windowNibName
{
return @"MyDocument";
}

@end


 nothing from the original document class is being executed anymore?
this project loads the "MyDocument2" object window correctly,   but  
then doesn't load the actual MyDocument object or it's window.


thanks for any help in advance on letting me know the fundamental  
thing i'm missing in how Cocoa document based apps start up..

Jon.

main nib, firing a secondary nib and it's controller....

2009-10-03 Thread jon

i want to have a WindowController object and it's own nib separate  
from the main nib..


but i want this secondary nib and controller to fire up when the  
application launches...


what is the best way to do that?

thanks in advance,

Re: main nib, firing a secondary nib and it's controller....

2009-10-04 Thread jon

thanks,  as a follow up,   is this the proper way to create and open  
the instance? (also globally, so it can be used in other parts of the  
app?)
can this be improved on?  (starting up a window Controller object and  
it's xib file)


thanks for the suggestion.
-Jon.

I also need to deallocated the instance on closing of the window...

---
#import 
#import "WebViewController.h"

@interface AppDelegate : NSObject
{
}

@end
---
#import "AppDelegate.h"

static WebViewController *webViewController = nil;

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)notification
{
	webViewController = [[WebViewController alloc]  
initWithWindowNibName:@"WebViewController"];

}

@end

Create and open an instance of that WindowController subclass from  
your app delegate's -applicationDidFinishLaunching: method.

wait for the event?

2009-10-05 Thread jon

i have a webView loading,   and need to wait until it is finished  
loading...


so far i've set up this notification in the wakeFromNib:

NSNotificationCenter *center = [NSNotificationCenter  
defaultCenter];
[center addObserver:self  
selector:@selector(webViewProgressFinished:)   
name:WebViewProgressFinishedNotification object:offScreenWebView];


and then i have a selector/method like so,  with nothing in it,   
because i'm not sure what to put in it yet...


- (void)webViewProgressFinished:(NSNotification*)notification
{
NSInteger i = 1;
}

and then i have a the main method that is running along,  and at a  
certain point below i need to wait for that notification to fire... Or  
that method to fire... same thing...
i need a little push in the correct direction,  because i really am  
stumped in whether to use some sort of NSRunLoop, or NSEvent,  or what  
would it be?


URLToLoad = [NSURL URLWithString:theUrlString];
[offScreenWebView setFrameLoadDelegate:self];
   	 [[offScreenWebView mainFrame] loadRequest:[NSURLRequest  
requestWithURL:URLToLoad]];


[[NSRunLoop currentRunLoop] runUntil... we get that darn message?];

here is where i need to wait until i get that message, or that that  
method is fired...
I seem to have the selector firing correctly i believe ...   but i  
don't know how to wait until it fires?

that is what i have so far...
and help would be appreciated greatly...

thanks,
Jon.

Re: wait for the event?

2009-10-05 Thread jon

I had a bunch of arguments in the method and a returning boolean  
value,   which hampered the effort...  I'm in the process of making  
them variables in the class,  so i can get it down to a void method  
with no arguments,  and am putting the rest of the method into the  
selector as you suggested...


now i've got a new problem,   i have two methods that are similar,  
that run for different webpages,  but use the same offscreen  
webView,   so i need to have the notification select two different  
method/selectors (or one with a flag)  (because the code that ends up  
in them is vastly different)..  so i'm going to have to have yet  
another flag that says, "go off and do two different things" at the  
selector method  i'm trying to figure that out now too.  If anyone  
has a suggestion on that,  that would be great too...


sorry for terminology,  i'm still trying to wrap my brain around what  
to call things (how they work)...


interestingly,  i tried to put the


URLToLoad = [NSURL URLWithString:theUrlString];
[offScreenWebView setFrameLoadDelegate:self];
 	 [[offScreenWebView mainFrame] loadRequest:[NSURLRequest  
requestWithURL:URLToLoad]];


code into a secondary thread,   and let it run,  then had the thing  
exit to the main thread when it was done,  or so i thought,  but it  
appears to load
 it into it's own thread,  because the way i had it set up,  it  
immediately exited the secondary thread,  and then the notification  
fired sometime later


 i'm reverting to doing it in the main thread as you suggested...

here is what i was using as an example,   which does not work in the  
case of loading a webView for anyone thinking of doing it.  (or  
atleast i couldn't get it to work)

(last comment has the code example that i followed...)

Re: wait for the event?

2009-10-05 Thread jon


well there seems to be a problem,   I do the main Method like so,

- (void)loadThePage
{
URLToLoad = [NSURL URLWithString:theUrlString];
[offScreenWebView setFrameLoadDelegate:self];
	[[offScreenWebView mainFrame] loadRequest:[NSURLRequest  
requestWithURL:URLToLoad]];

}

@end

and i put the rest in the selector method like so...  to be executed  
when the page is fully loaded,  which works...  but the thing is,  the  
code immediately following the main call to "loadThePage" isn't  
waiting, it keeps on executing... which defeats the purpose,  the  
whole program needs that data.


//  
---

- (void) webViewProgressFinished:(NSNotification*)notification
{
didChange = NO;
	DOMDocument *myDOMDocument = [[offScreenWebView mainFrame]  
DOMDocument];

... etc

 if the webpage was quick to load it works   in reality the page  
takes a while to load,  and in the mean time,  the rest of my  
application  (the code after the "loadThePage" keeps on executing so i  
have not successfully controlled the running of the app.,  it is  
executing methods left and right,  without the finishLoadingTheWebPage  
ever being called until half the application has already executed...


putting the loading into another thread results in the same thing,
the rest of the application needs the data,  so it can not be running  
until the webPage is fully loaded...


so i have to use a combination,  i need to put in a flagging type of  
thing, and have the runLoop wait for that flag,  the flag needs to be  
in the "webViewProgressFinished"  to work (it was not before)..  yet i  
still need that flag



thanks,
Jon.

In general you don't want to wait for, uh what did you say? a  
selector to fire? You start an asynchronous operation (like  
loadRequest) and let the current run loop notify you. Exit the  
method after you do your loadRequest. When you get the notification,  
do your thing to finish it in webViewProgressFinished -- do the  
thing that you were waiting to do.


I could be wrong but I think you might actually be blocking the  
notification by doing the sit 'n spin bit with [[NSRunLoop  
currentRunLoop] runUntil... we get that darn message?];


Is there a reason you have to loop and wait for it to finish instead  
of doing more work in the notification method? If there is then  
maybe you should use a lock to synchronize the threads instead of  
waiting.


You might want to tell us more about what you're trying to do.


Matt

oh you've got that right,  I unfortunately have it ingrained for 25  
years of straight pascal in MacOS...  i could destroy a runloop with  
the best of them...


I wish i started cocoa 7 years ago, but it was not to be.  My  
brain is trying to refactor,  and it is fighting mightily... trying to  
keep up with the young-uns who have no such baggage...


I'll look into NSLock thanks,
Jon.
