问题
I have nearly completed my first app. In testing on the device, I am getting a crash when I press the home button, with the error message
libGPUSupportMercury.dylib`gpus_ReturnNotPermittedKillClient:
Based on these posts: https://stackoverflow.com/search?q=how+to+shut+down+OpenGL OpenGL ES crash on move background, iOS 5.1
I am pretty sure the problem is that my app is an extension of software that uses some sample code involving OpenGL (about which I have very little understanding) and that the OpenGL tasks are not shutting down properly on resignActive.
I tried the following in my AppDelegate with no luck:
- (void)applicationWillResignActive:(UIApplication *)application {
glFinish();
}
My app does not need to save any settings upon exit... it just needs to end. Can anyone suggest a solution?
回答1:
To finish program at user push home button ? on Xcode, choice Target and select Info tab. Custom iOS Target Properties, add a Key named
Application does not run in background
and set Value
YES
Try it!
p.s. Not necessary write glFinish().

I am now working on a Sprite Kit game and I had a similar problem.
Check if you have on the screen the node that tells the FPS, because that might be rendering and causing the crash.. It did for me.
In applicationWillResignActive method I call my pause method as all of you.
*edit - and check for audio playing
