如何与自己叠加声音？

Question

我是Xcode的新手，我想重复播放声音，无论是否已经播放。例如。我有三个正在拍摄的激光器，我希望激光声能同时播放三次，而不是等待每一个完成播放。如何使用AVAudioPlayer实现此目的？

Answer 1

这样做：

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];
