terminating uncaught exception of type NSException - ios

Question

My game is constantly crashing after pressing a certain button after restarting the game.
An animation is always running during the game in the ViewController I'm running the game on.
Here is the crash log. Is there any way to detect how is this crash related to my animation?

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)
When I press buttons in the view , the app crashes. Here is the animation code:
CABasicAnimation *fullRotation = [CABasicAnimation animationWithKeyPath:#"transform.rotation"];
fullRotation.fromValue = [NSNumber numberWithFloat:0];
fullRotation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
fullRotation.duration = 4;
fullRotation.repeatCount= 1000;
[[stick layer] addAnimation:fullRotation forKey:#"60"];}
I'm sorry if the code is messed up , I'm still learning and building small apps and games to get a better practice. Thanks.

Answer 1

You should remove the lines with fullRotation.fromValue, since it ought not to have a CALayer assigned to itself.
fullRotation.fromValue = self.view.layer.presentationLayer;
