如何利用声音本身来演绎声音？

Question

我刚接触Xcode中的声音，我希望重复播放一个声音，无论它是否已经在播放。例如：我有三个正在拍摄的激光，我希望激光声音同时播放三次，而不是等待每一个都播放完。如何使用AVAudioPlayer实现这一点？

Answer 1

执行以下操作：

AVAudioPlayer *laserSound1  = .........
laserSound1.numberOfLoops = 2; //plays three times simultaneously
[laserSound1 play];

 AVAudioPlayer *laserSound2  = .........
laserSound2.numberOfLoops = 2;//plays three times simultaneously
[laserSound2 play];

AVAudioPlayer *laserSound3  = .........
laserSound3.numberOfLoops = 2;//plays three times simultaneously
[laserSound3 play];
