Answer 1

Check if you have the FPS node on the screen, it might be rendering..

*edit - and check for audio playing

Answer 2

Technically, the last method you can make OpenGL calls from is this one:

- (void)applicationDidEnterBackground:(UIApplication *)application

Although it is often a good idea to suspend drawing after applicationWillResignActive, this is just a recommendation and some apps have requirements beyond this. What is actually enforced is that you cannot make any OpenGL calls once your app moves to the background.

From the docs:

Once your application exits its applicationDidEnterBackground: method, it must not make any new OpenGL ES calls. If your application makes an OpenGL ES call, it is terminated by iOS.

Also, remember to include glFinish() as your final GL call.

Answer 3

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]
