AudioToolbox循环播放本地音频，简单使用

导入AudioToolbox.framework

• (void)playSoundEffect:(NSString*)name {

     //获取文件的路径
     NSString *audioFilePath = [[NSBundle mainBundle] pathForResource:name ofType:@"wav"];
      NSURL *fileUrl = [NSURL fileURLWithPath:audioFilePath];
      SystemSoundID soundID = 0;
      AudioServicesCreateSystemSoundID((__bridge CFURLRef)(fileUrl), &soundID);
      
      //播放并且监听是否播放完成
      AudioServicesPlaySystemSoundWithCompletion(soundID, ^{
        NSLog(@"播放完成回调");
        //设置播放完成之后外部回掉，不能直接播放，需配合AudioServicesPlaySystemSound（soundID）使    用
        AudioServicesAddSystemSoundCompletion(soundID, NULL, NULL,systemAudioCallback, NULL);
        AudioServicesPlaySystemSound(soundID);
    });
  

}

void systemAudioCallback(){
NSLog(@"播放完成2");
}
