Question

I have a little issue about my application iOS.
When i’m using the iOS simulator 5.1 ipad/iphone the application is working, but when i use a real iOS device (iPad and iPhone 5.1 too)

the application crashes when moving on background after clicking on home button…
with this error:

libGPUSupportMercury.dylib`gpus_ReturnNotPermittedKillClient:
0x33240094:  trap   
0x33240096:  nop 

I found out that it’s was OpenGL ES that was still calculating and making the application crash and found this function: glFinish();

But that still not working here a sample of my code:

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [[CCDirector sharedDirector] resume];
}

- (void)applicationWillResignActive:(UIApplication *)application {
    glFinish();
    [[CCDirector sharedDirector] pause];
}

I think the problem is just here
Is there someone who have an idea of my problem ?
Thanks

EDIT:

Problem solved with that:

- (void)applicationDidEnterBackground:(UIApplication *)application
{
[[CCDirector sharedDirector] stopAnimation];
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
[[CCDirector sharedDirector] startAnimation];
}

maybe that can help someone x)

In iOS 5.1 it is enforced that you cannot make a call to OpenGL after you have been requested to resign active.

- (void)applicationWillResignActive:(UIApplication *)application

Is the place to stop everything, whether it be a CADisplayLink or a [[CCDirector sharedDirector] stopAnimation]
