OSSpinLockLock이 반복적으로 발생했으며 lldb가 이에 대한 적절한 callStackSymbols를 표시하지 않습니다.SpriteKit iOS7을 사용하여 게임을 프로그래밍 할 때 OSSpinLockLock 문제를 해결할 수있는 사람이 있습니까?
다음은 내가
내가 [NSThread callStackSymbols]하여 더 많은 문자를 얻기 위해 시도했지만이 경우에는 효과가 없습니다 Xcode의 버전 5.0.1 (5A2034a)의 lldb에서 가져온 것입니다.
이것은 SpriteKit (iOS7)에서만 발생합니다. SKEmitterNodes 주변에서 수십 번 확인했지만 내부에는 버그가 없습니다. Birzarrely 충분히 때때로 copyWithZone는 : 메시지는 다음과 같은 고속 발사체에 정상적으로 작동하지 않을 수
SKEmitterNode * 템플릿 = NSKeyedUnarchiver unarchiveObjectWithFile [[NSBundle mainBundle] pathForResource "cannonball_flame"ofType @ @ "SKS" ]]; .... ... [템플릿 사본]; // -> 어떤 경우에는 좋지 않음
이 문제를 해결할 사람이 있습니까? SpriteKit 버그 때문입니까?
