iPad Programming Tutorial
Hi All, Does anyone know of a resource that helps understand how to NOT use interface builder for developing applications? I am trying to create a iPad SplitView application and I dont quite understand if I want to put code to create additional interface elements in: - (void)configureView or - (void)viewDidLoad Say I wanted to add a UITextView and display it. Wouldn't I do something like: CGRect bounds = [[UIScreen mainScreen] applicationFrame]; UITextView *theTextView = [[UITextView alloc] initWithFrame:bounds]; [theTextView setContentView:theTextView]; [theTextView makeKeyAndOrderFront:nil]; [theTextView makeFirstResponder:theTextView]; [theTextView show]; But I dont know if it displays, I was thinking that maybe this is something to do with that fact the project uses Interface Builder and I dont want to. -ML ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Accessibility for NSTableView
Hi!
I have a table view which lists files. I would like to make the represented
objects available through Accessibility. I.e. I want to add
NSAccessibilityURLAttribute and NSAccessibilityFilenameAttribute to the table
rows.
So far, I have come up with this:
- (id)accessibilityHitTest:(NSPoint)point;
{
NSObject *row = [super accessibilityHitTest:point];
if (row != nil) {
@try {
NSNumber *rowNumber = [row valueForKey:@"row"];
NSObject *dataSource = [self dataSource];
ResultItem *resultItem = [dataSource tableView:self
objectValueForTableColumn:nil row:[rowNumber intValue]];
[row accessibilitySetOverrideValue:[resultItem pathURL]
forAttribute:NSAccessibilityURLAttribute];
[row accessibilitySetOverrideValue:[resultItem path]
forAttribute:NSAccessibilityFilenameAttribute];
}
@catch (NSException *exception) {
NSLog(@"exception: %@", exception);
}
}
return row;
}
Sadly, this is not working. Neither attribute is visible in the Accessibility
Inspector.
Best,
Pierre Bernard

Re: Temporarily enabling layer backing for NSView
Try calling -display after -setWantsLayer:
The view needs to be drawn once into the layer before being able to animate.
Another way of achieving the desired result is to draw the initial and target
view into images and then animate the swapping of image views.

Re: NSRuleEditor: Criteria for new row
I was able to fake it by subclassing a private method:
- (void)_addOptionFromSlice:(id)slice ofRowType:(unsigned int)type
{
int rowIndex = [(NSRuleEditorViewSlice*)slice rowIndex];
NSArray *criteriaForRow = [self criteriaForRow:rowIndex];
NSArray *displayValuesForRow = [self displayValuesForRow:rowIndex];
self.template = [NSArray arrayWithObjects:criteriaForRow,
displayValuesForRow, nil];
[super _addOptionFromSlice:slice ofRowType:type];
}
- (void)insertRowAtIndex:(NSInteger)rowIndex
withType:(NSRuleEditorRowType)rowType asSubrowOfRow:(NSInteger)parentRow
animate:(BOOL)shouldAnimate
{
[super insertRowAtIndex:rowIndex withType:rowType
asSubrowOfRow:parentRow animate:shouldAnimate];
NSArray *template = self.template;
if (template != nil) {
[self setCriteria:[template objectAtIndex:0]
andDisplayValues:[template objectAtIndex:1] forRowAtIndex:rowIndex];
}

NSDateFormatter formats from NSLocale
Hi! I am trying to format dates for display. So far I have been using this formatter: NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4]; [dateFormatter setDateStyle:NSDateFormatterShortStyle]; [dateFormatter setTimeStyle:kCFDateFormatterMediumStyle]; Now, I want to add leading zeros to days and month values. It seems there is no way of teaching the above formatter to do so. It goes with whatever format the user has set in System Preferences. Thus I am trying the below formatter: NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4]; [dateFormatter setDateFormat:@"dd/mm/yy hh:MM:ss a"]; This works fine, except for the fact that I have now hardcoded the fact that I display day/month/year rather than month/day/year. It would seem that NSLocale should know about the user's preferences. Yet I can find no way to query it for date format.

Hi Sean, I want to respect the user's locale, yet ignore his/her preferences as to formatting. I thought about modifying the format I get from the standard styles. I would however expect NSLocale to know the correct order of elements in the date format. Pierre So you want to use the user's preference and yet you don't.

Figured out one way to get the desired result. But really don't like it. I'd much rather have NSLocal tell me if day or months value should go first.

Re: CATiledLayer documentation
Hi Bill! I had indeed found your sample code. Which actually happens to be the only sample code I could find. Unfortunately, the sample code left me confused. Seems to me that your drawing method always does the same thing. I find no notion of tiling. Obviously there is: when I set a breakpoint on the drawing method I can clearly see the view being drawn bit by bit. I just don't understand how it works. Of course, I would have hoped for an example with multiple image source containing tiles. I wanted to access the web site of your book. I was hoping for an eBook to purchase. The server however hasn't been responding all day. Best, Pierre Bernard Houdah Software s.à r.l.

CoreData mystery: configuration used to open the store is incompatible...
Hi! I am puzzled! I have run into this weirdest problem. It only happens if I target Tiger. I am working on an update to HoudahGeo and suddenly, my current build refuses to open documents. This includes both existing documents and documents created by the running application. The error is: Error Domain=NSCocoaErrorDomain Code=134020 UserInfo=0x2b7b10 "The model configuration used to open the store is incompatible with the one that was used to create the store." NSUnderlyingException = Can't find table for entity MovieReference in database at URL file://localhost/Users/pierre/Desktop/HoudahGeo-Leopard.hgeo ; There is no MovieReference entity in the model.

When I target Leopard with the same code all works fine. It occurs on both 10.5.5 and 10.5.6 When I compile an older version of the project, it works just fine. Thus I broke something with my recent changes. Yet I have no idea what. I did not touch the model.

Re: NSNetService & NSURLConnection on Tiger
Hi!
This is what I came up with:
@implementation NSNetService (ipv4)
- (NSArray*)ipv4addresses
{
NSMutableArray * ipv4addresses = [NSMutableArray array];
NSArray *addresses = [self addresses];
int aCount = [addresses count];
char addr[256];
for (int i = 0; i < aCount; i++) {
struct sockaddr *socketAddress = (struct sockaddr *)[[addresses
objectAtIndex:i] bytes];
if (socketAddress && socketAddress->sa_family == AF_INET) {
if (inet_ntop(AF_INET, &((struct sockaddr_in *)socketAddress)-
>sin_addr, addr, sizeof(addr))) {
uint16_t port = ntohs(((struct sockaddr_in *)socketAddress)-
>sin_port);
[ipv4addresses addObject:[NSString stringWithFormat:@"%s:%d",
addr, port]];
}
}
}
return ipv4addresses;
}
@end

See the documentation for -[NSNetService addresses]. You can use that
to go from NSNetService -> NSData -> sockaddr_in -> NSURL ->

Re: NSInMemoryStoreType: Not really "persistent", is it?
(I did a little demo app at one point long ago that used an in memory store to cache results from Amazon's web services API. The front end was all pure Cocoa / bindings / CD with a minimal amount of additional code to pull data from amazon and push it into the local store). Is that demo available some place?

NSRuleEditor/NSPredicateEditor selected rows
Hi! NSRuleEditor has the concept of selected rows in its API. I however see no visual clues of which rows are selected. Is it possible to subclass whatever cell view is used by the rule editor to add such a visual clue?

Window title bar accessory view
Hi! I would like to replicate the accessory views found in the top right of window title bars. Examples include Coda, iCal, Safari,... How can I add subviews to the window's title bar?

Re: Window title bar accessory view
Hi Andrew, No I am not talking about the toolbar. I am referring to the lock icon and the new green certificate information text displayed by Safari in the window's title bar. iCal displays a pop-up menu where one can pick the time zone.

Pierre Greetings, Pierre, I think that what you're referring to is the toolbar (class NSToolbar), as I don't see anything besides that at the top of my iCal or Safari windows. (On Leopard, the Unified Title/Toolbar setting in Interface Builder, or through code, makes the title bar, which is actually separate, look connected to the toolbar.) If you can afford to target Leopard-only and are willing to put up with a slightly buggy interface, you can use Interface Builder to set up the toolbar in the window itself and store it in the nib or xib that way. Otherwise, if for whatever reason that won't work for you*, you may wish to use a toolbar delegate to handle the configuration of the toolbar. The docs have much more info, as well as "dos" and "dont's" of toolbars (for instance: anything in a toolbar, last I checked, should have a menu item equivalent; thus if you have a Reset button or a Send button or whatnot in your toolbar, there should be a Reset or Send menu item, accessible from the menu bar). Hope this helps! * Selectable toolbar items are one example of why the Interface Builder approach may no work for you -- such items are not currently configurable in IB. (They're the sort of item used in the iTunes preferences window, where they act like push-buttons of which only one can be selected at a time.)

Re: Window title bar accessory view
Hi Kyle! Thanks a lot. This sounds like a great idea. I will give it a try ASAP.

If so, use -[NSWindow standardWindowButton:] to get an NSButton instance, and then use -[NSView superview] to get at the window frame view. Then use -[NSView addSubview:] to add your custom view and position it accordingly. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Drag & Drop: PREVENT file move
Hi! My application shows a list of files in a table view. I have implemented drag and drop so that users may drag files from the list. I could envision them dragging the files onto other applications for viewing or dragging them on a removable media to create archive copies. The problem occurs when the user drags the file to another folder on the same disk. By default, the Finder then wants to move the file. I need to prevent just that as it will cause havoc. For one, I would lose track of the file. Is there a way for the originating application to control the allowed drag operations?
