Body
I've come across this 3MB malloc done by CoreVideo on my iPad app after releasing an MPMoviePlayerController object. I've made sure that the player is stopped before released, so it does actually release memory and deallocs properly. The thing is that instruments keeps showing this malloc that hasn't been released (and is not used directly by me in my code) This is the call that's shown in instruments as responsible caller for the 3.52MB Malloc that's never released. <pre><code>CVPixelBufferBacking::initWithPixelBufferDescription </code></pre> Here's the code where the players are stopped and the array that contains them released <pre><code>- (void)dealloc { ... [self stopAllPlayers]; [_moviePlayerViewControllerArray release]; [super dealloc]; } -(void)stopAllPlayers { for (MPMoviePlayerController *mp in _moviePlayerViewControllerArray) { [mp stop]; } } </code></pre> here's the method that adds the video <pre><code>-(void)addVideo:(NSString*) videoName onRect:(CGRect)rect { ...... MPMoviePlayerController * movieController= [[MPMoviePlayerController alloc]initWithContentURL:(NSURL *)videoURL]; // set frame for player movieController.view.frame = rect; // set auto resizing masks [movieController.view setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight]; // don't auto play. [movieController setShouldAutoplay:NO]; [pdfView addSubview:movieController.view]; [pdfView bringSubviewToFront: movieController.view]; [_moviePlayerViewControllerArray addObject:movieController]; [movieController release]; } </code></pre> EDIT: added image<img src="https://i.stack.imgur.com/hYL4w.png" alt="instruments zombies on simulator (obviously)">. the beautiful 3MB malloc in all it's glory. <img src="https://i.stack.imgur.com/1wzgT.png" alt="This other screenshot is the allocations instruments running on the ipad.e"> as you can see the other chunk of memory is no longer there but I still have a major problem. thanks in advance for your help

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
