NSString *pathString = [[NSBundle mainBundle] pathForResource:@"音频文件" ofType:@"mp3"];
NSURL *fileUrl = [NSURL fileURLWithPath:pathString];
SystemSoundID soundID = 0;
AudioServicesCreateSystemSoundID((__bridge CFURLRef)(fileUrl), &soundID);
AudioServicesPlaySystemSoundWithCompletion(soundID, ^{
// 播放完成后的操作
});
AudioServicesPlaySystemSound(soundID);
这样声音只能受铃声音量控制，不受系统音量控制
