Releasing a MPMoviePlayerController...

[Johanovski]

Hi all!

I'm using a MPMoviePlayerController just at the beginning of my app to show an intro, and after that I want to release the instance. I've tried calling a function with a timer and I thought this should did the trick, but after doing some tests and traces I've found that instance isn't being fully released and a some leaks appeared in the instruments. I'm showing you what I do:

// GameAppDelegate.h

(...some code...)

@interface OGLGameAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    EAGLView *glView;
	MPMoviePlayerController *theMovie;
}

(...some code...)

// GameAppDelegate.m

(...some code...)

- (void)applicationDidFinishLaunching:(UIApplication *)application {
    
	[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];
	
	NSBundle *bundle = [NSBundle mainBundle];
	
	NSString *moviePath = [bundle pathForResource:@"test" ofType:@"m4v"];
	NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
	theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
	
	//NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
	//MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
	
	theMovie.movieControlMode = MPMovieControlModeHidden;
	
	[theMovie play];
	
	[NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:@selector(endVideo) userInfo:nil repeats:NO];
	
	glView.animationInterval = 1.0 / 60.0;
	[glView startAnimation];
}

- (void) endVideo
{
	[theMovie stop];
	[theMovie release];
	NSLog(@"RT:%d",[theMovie retainCount]);
}
(...some code...)

What trace show when movie should be released is the following:

...[1163:207] RT:2

But if I try to release theMovie 2 more times, after the function has ended seems that something tries to access the instance and it throws an error, which is the following with NSZombieEnabled:

...[1028:207] *** -[MPMoviePlayerController release]: message sent to deallocated instance 0x9438480

And, working with Instruments, 9 leaks appeared:

Leaked Object: NSCFString
#: 9
Address: <multiple>
Size: 1,62 KB
Responsible Library: Foundation
Responsible Frame: -[NSCFString

Does anyone knows what can be happening and what can I do to prevent this? I don't want to keep theMovie living during all game life, but I don't know how to make theMovie release itself or be released when it stops (I've also tried calling the "moviePlayBackDidFinish" method, but it never gets called...

Thanks in advance!
