好的,大家好,我一直在开发一个应用程序,其中有一个NSMutableDictionary对象,并且其中包含了一个SKAction对象,该对象用于播放声音。
这一切都很顺利,但是...当进入后台时,应用程序会崩溃,并显示以下堆栈跟踪:

由于显示“EXC_BAD_ACCESS”,我怀疑是僵尸对象,但在方案中启用它们并没有帮助理解此崩溃。
即使在最简单的项目设置(仅有两行代码)中也会发生这种情况,位于MyScene.m中:
self.arrSounds = [[NSMutableDictionary alloc] init];
[self.arrSounds setObject:[SKAction playSoundFileNamed:[NSString stringWithFormat:@"70.caf"] waitForCompletion:NO] forKey:[NSString stringWithFormat:@"1"]];
这怎么可能呢?
