Re: Subclassing UIWebview a show-stopper?
Hi Arri, Subclassing UIWebView is probably not going to get your app rejected (though I have no insight in to the approval process). However from a architecture point-of-view, it smells bad. UIWebView is one of those views that's not intended to be subclassed. Sure you can, since you can declare anything as your superclass, but I'd be highly surprised if the UIWebView authors are even expecting people to subclass it. If they're not, then that could mean that there's logic in there that operates on the assumption of none of the methods being overridden. There are certainly classes like that in all of the Cocoa (Touch) frameworks. This sounds like one of the things that I'd only go ahead with after I've proven that every other idea presented isn't possible.

However, as everyone emphasize everywhere i look, the docs say i should not subclass UIWebView. Perhaps this is more about the english language than about software development or Apple, but what does should exactlty mean in this context. Will Apple possibly reject the app if i use a UIWebView subclass? Or does it mean how i've always understood the word should and i could read the docs as such: …there shouldn't be a need to subclass…. In other words: subclassing UIWebview will not result in a rejection. thanks, arri ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

blocks and retaining CoreFoundation objects
I have a slow image conversion which I want to throw onto a background thread
using GCD. The actual method which does the conversion takes a CGImageRef and
the code looks like this
-(void)convert:(CGImageRef)image withBlock:(ImageResizedBlock)callbackBlock
{
dispatch_async( dispatch_get_global_queue(
DISPATCH_QUEUE_PRIORITY_DEFAULT, 0 ), ^{
CGImageRef converted = [ self createConvertedImage:image ];
callbackBlock( converted );
CGImageRelease( converted );
} );
};
I quickly found that whereas NSObject(s) are retained by the block,
CoreFoundation objects don't appear to be, so image can be, and usually is,
released before the block runs, causing an exception.
One way to fix this is to add a CFImageRetain() before the dispatch_async() and
a CFImageRelease() inside the block at the same place converted is released,
which works, but I for some reason don't like, probably because the retain is
outside the block and the release is inside it and it seems odd to me.
After a bit of googling I came across some posts which explained Block_Copy()
would treat a variable adorned with __attribute__((NSObject)) similarly to
NSObjects and retain them. So changing the method signature to this
-(void)convert:(__attribute__((NSObject))CGImageRef)image
withBlock:(ImageResizedBlock)callbackBlock
appears to do the right thing in my testing, the CGImageRef is CFRetain()ed
when the block is enqueued and I assume CFRelease()d later. I prefer this
syntax, as I find it self-documenting;
I can't find anywhere apart from blog posts and the block specification itself
which says this works. Does anyone know if it's officially supported, for gcc
and clang and something that apple is likely to support going forward into ARC
etc. ___

Lingering windows
I have a document-based application that uses garbage collection. It's straight-forward in terms of having subclasses of NSDocument, NSWindow, and NSWindowController, and documents have a single window (with drawer, if that makes any difference). But when I close a window/document, the window gets orderedOut, so it never closes. I can, for example, use the scripting interface after a document has been closed and make its window visible again. When I close I see performClose: being called, windowShouldClose: being called on the delegate (the window controller), then close on the window, followed by windowWillClose: on the delegate, and then orderOut on the window.

CGContextShowTextAtPoint doesn't show text
I am having a problem with rendering text on a CALayer.
AFAIK, it works just fine with all users ... except one, where the text just
does not show!
This is my code for printing the text:
@interface TextLayerDelegate : NSObject
{
// ...
}
- (void) drawLayer: (CALayer *) theLayer inContext: (CGContextRef) theContext;
@end
@implementation TextLayerDelegate
- (void) drawLayer: (CALayer *) theLayer inContext: (CGContextRef) ctxt
{
// ...
const char * str = [mesg cStringUsingEncoding: NSMacOSRomanStringEncoding];
// encoding must match with CGContextSelectFont() below
if ( str strlen(str) )
{
CGContextSetShouldAntialias( ctxt, TRUE );
CGContextSetRGBFillColor( ctxt, 1.0, 1.0, 1.0, 1.0 );
CGContextSelectFont( ctxt, AndaleMono, 14, kCGEncodingMacRoman ); //
Andale Mono doesn't work either
CGColorRef blue = CGColorCreateGenericRGB( 0.0, 0.0, 1.0, 1.0 );
CGContextSetShadowWithColor( ctxt, CGSizeMake(0,0), 10, blue );
CGContextShowTextAtPoint( ctxt, theLayer.bounds.origin.x + 7.0,
theLayer.bounds.origin.y + 7.0, str, strlen(str) );
CFRelease( blue );
}
}
I have checked that 'str' does actually hold a valid string at the user's
instance. (I logged it and had him send me the log file.)
I have also tried different font sizes.
I have also googled around.
All to no avail.
Does anybody have an idea what else might be wrong?
Thanks a lot in advance.

Thank you, Kevin. That seems to work; at least, it has worked for a day.
As usual when dealing with NSDocument, the answer is to override as high as

Here's the revised code for anyone else playing with customized autosave. Now
simpler and safer, because we're only dealing with autosave…

Insert code here to queue an operation or block to be run when other

Re: [Lion] IBOutlets, strong or weak?
Thanks a lot Josh and Sean. I never remember to read the release notes but I just went through AppKit's. I'm going back to the straight iVar style for Mac OS X for now. I was putting them all in the class continuation category anyway since they shouldn't be exposed externally.

This is true for outlets generated in new projects as well as when adding new outlet declarations from Interface Builder.

Hide Quicktime logo when using MPMoviePlayerController to play audio
Reference my iOS TabController app...
Apple docs state that the AVAudioPlayer class does not provide support for
streaming audio based on HTTP URL's. AVAudioPlayer plays only music embedded in
the iApp.
Given that, I do use MPMoviePlayerController to play these web stored audio/mp3
files which it can handle.
This definitely works. I start out with a UIView with the lyrics for the song.
At the very bottom of this lyrics UIView is a Play button. The user taps this
button and the audio/mp3 plays; however, the audio/QuickTime (( Q )) graphic
comes to the foreground and the lyrics disappear and will stay away until the
user taps Done.
What I want to happen is that the audio/mp3 is played, but the lyrics stay in
front.
BTW, I really don't think I need the Done button to be seen because the user
can stop the audio by simply selecting another Tab.
Obviously this coming to the foreground for the AV Quicktime graphic makes
sense because the MPMoviePlayerController object is primarily designed to play
video and the video ought to come to the front. Therefore, it is consistent in
that the Quicktime graphic also comes to the foreground.
BUT, I really do need a way to defeat the audio/QuickTime (( Q )) graphic
coming to the front and keep the lyrics there.
I did insert code to determine if it was an audio file (mp3), versus a video
file (mp4). So far so good ... and then if it was an audio file, within my
actual playing segment, I have:
if ( NSClassFromString(@MPMoviePlayerViewController) )
{
if (!isAudioFile)
{
[senderViewController
presentMoviePlayerViewControllerAnimated:moviePlayerViewController_];
}
}
[moviePlayerController_ play];
It actually works, that is, I actually hear the mp3 in the background, with the
lyrics staying in front and the audio/QuickTime (( Q )) graphic does not show …
**BUT, what does happen is horrible, that is, the Done button shows over the
lyrics** I talked about with some sort of unknown ??? letters there. The
gibberish that appears looks line the Done label for the UIButton
superimposed on which is the time remaining to finish the song.
FWIW, I really don't think I need a Done button because as soon as I go to
another tab, either new music or a video, the music initially playing stops and
the new AV file starts. If I press the Home button, the music stops playing,
so I think I can get along without the Done button being around.
Any ideas to cover over the Done button ?? ... because right now I don't have a
clue what to do.

Verify my Understanding
I think I get it re: printing but would like some verification of my understanding. When printing, the printing context coordinate system is measured in points (pt = 1/72 inch). When getting paper size it is returned in points. The printing context is device independent. So, to print an exact size bitmap of mine I just need to convert its dimensions to points. So if my bitmap is measured in tenths of a millimeter I set its rect to be drawn in to (bitmap width * 72/254) and (bit map height * 72/254).

Are Strings defined using #define good enough as String constants? Or Should I be doing this another way? When working with a framework like Cocoa, I'd follow its lead. In this case, that's to define global constant NSString pointers: // --- in MWSService.h /*! Default endpoint URL for MWSService. */ MWS_EXPORT NSString * const MWSServiceDefaultEndpointURL; // --- in MWSService.m NSString * const MWSServiceDefaultEndpointURL = @http://www.example.com/endpoint;; The macro MWS_EXPORT should be the typical extern without C++ name mangling macro: #if defined(__cplusplus) #define MWS_EXPORT extern C #else #define MWS_EXPORT extern This is needed because if you compile some of your code as Objective-C and other as Objective-C++, without the C part of 'extern C' your global can wind up with C++ name mangling. The NSString * const means the pointer is constant, so the optimizer can assume it's unchanging. That'll be the case because you'll wind up with only one copy of the string in your built product (whether it's a library or executable). That won't necessarily be the case for a #define - if you used a #define in a framework header, and built an OS X app that embeds the framework, you'd actually have separate copies of the string in the app and the framework. (And -isEqual: implementations are generally smart about immediately returning YES when passed self, but falling back when not.) In short: Do like Apple, use an NSString * const global. -- Chris ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Lingering windows
On Aug 9, 2011, at 05:24 , Shane Stanley wrote: I have a document-based application that uses garbage collection. It's straight-forward in terms of having subclasses of NSDocument, NSWindow, and NSWindowController, and documents have a single window (with drawer, if that makes any difference). But when I close a window/document, the window gets orderedOut, so it never closes. I can, for example, use the scripting interface after a document has been closed and make its window visible again. When I close I see performClose: being called, windowShouldClose: being called on the delegate (the window controller), then close on the window, followed by windowWillClose: on the delegate, and then orderOut on the window. It's not entirely clear what it is you're expecting here. AFAICT -- and I have spent some time pondering the documentation and APIs on this -- there really *isn't* anything that you could call closing a window other than the sequence you describe above. Again AFAICT, window closing and ordering-out are indistinguishable, for all practical purposes at least. The only difference that might happen at close time, which you'd normally want for a document window, is that the window might get released. (In GC terms, there might be no strong references and so the NIB objects can get garbage collected.) That's where things can get a little murky, because there are sometimes unexpected strong references. The most obvious cause of this kind of lingering is the NIB mechanism itself. Normally, top level objects in a NIB receive an extra retain when loaded (have an extra strong reference, in the GC case). For windows specifically, there is a checkbox in IB that says release when closed. For a document window, you should check this box so that (presumably) when the window is closed the extra strong reference is discarded. I suspect this is the cause of your window's lingering. If that's not it, then use the debugger's 'info gc-roots' command (having set a breakpoint somewhere after the window has been closed and the collector has had time to run, preferably) to find out what's keeping the window alive.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Lingering windows
On Aug 10, 2011, at 3:51 AM, Quincey Morris wrote: It's not entirely clear what it is you're expecting here. What I'm expecting is that when I close a document, the document, the window controller and the window will disappear. AFAICT -- and I have spent some time pondering the documentation and APIs on this -- there really *isn't* anything that you could call closing a window other than the sequence you describe above. Again AFAICT, window closing and ordering-out are indistinguishable, for all practical purposes at least. I only noticed the problem from the scripting interface. Let's say I have two documents open: the (pretty standard) scripting interface shows two documents and two windows. If I close the documents, it shows no documents but still two windows -- which I can make reappear by setting their isVisible property. The only difference that might happen at close time, which you'd normally want for a document window, is that the window might get released. (In GC terms, there might be no strong references and so the NIB objects can get garbage collected.) That's where things can get a little murky, because there are sometimes unexpected strong references. The most obvious cause of this kind of lingering is the NIB mechanism itself. Normally, top level objects in a NIB receive an extra retain when loaded (have an extra strong reference, in the GC case). For windows specifically, there is a checkbox in IB that says release when closed. For a document window, you should check this box so that (presumably) when the window is closed the extra strong reference is discarded. I have Release when closed checked, but the docs say: Release when closed, however, is ignored for windows owned by window controllers. Elsewhere it says: The general behavior is as follows: • When the last window of a document is closed, the document is also closed. The window, window controller, and document are all released. I'm trying to understand what might stop that from happening. If that's not it, then use the debugger's 'info gc-roots' command (having set a breakpoint somewhere after the window has been closed and the collector has had time to run, preferably) to find out what's keeping the window alive.

[SOLVED] Re: CoreData I/O error for database: no such table
On Aug 8, 2011, at 4:35 AM, Nick Shore wrote: I was in fact using existing databases - actually the update I'm working on has a migration involved in it too. I didn't mention it originally as I'd ruled it out as the cause, but that actually helped fix the problem. Since I was already migrating the data (with custom entity migration policies) it was trivial to rename the relationships at the same time. And that worked - the migration can read the existing database and it fixed my issue when attempting to read the new one. And that turned out to be the solution. I was already working on a new data model at the time, so I turned it on and made a mapping model, and the migrator created a database that doesn't generate any I/O errors when the app tries to access the object with the many-to-many relationship. The really strange part is, I did not rename the many-to-many relationship between database versions, and in the migrated database, the many-to-many table is not called Z_16PARENTS as I expected would happen after the migration.

NSTableView: move rows through drag and drop?
I implemented drag and drop in an NSTableView by writing the row indexes of the rows to be copied/moved to the pasteboard, which works. Now I want to allow drag and drop from one document to another, and my first guess was to write the row data to the pasteboard. What puzzles me, is how to delete the row data from the source data, in case of a move. That is, my acceptDrop inserts the row data into the destination data source, but the indexes of the source rows are not available at this point. Of course, I can add row numbers to the row data on the pasteboard, but this is a bit double. What is the standard approach to this? --- Grinnikend door het leven... ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Lion's new Resume feature, document restoration, and splash screens
I just got back to this problem (after watching the WWDC11 Resume and Automatic Termination video).
