Question

使用AudioToolbox按一个按钮后，我播放了这个声音。

-(void) onButtonPressSound {
    NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"sound" ofType:@"m4a"];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath: soundPath], &soundID);
AudioServicesPlaySystemSound (soundID);

}

按下此按钮后，如何让它播放2个声音而不是一个，一个接一个？

谢谢，

有两种方法可以做到这一点：第一个：像我这样懒惰的人:) 发出一个接一个播放2个声音的声音。另一个：

SystemSoundID receiveMessageSound1;
SystemSoundID receiveMessageSound2;
NSString *sendPath1 = [[NSBundle mainBundle] pathForResource:@"Music1" ofType:@"wav"];
            CFURLRef baseURL = (__bridge CFURLRef)[NSURL fileURLWithPath:sendPath];
            AudioServicesCreateSystemSoundID(baseURL, &receiveMessageSound1);
            AudioServicesPlaySystemSound(receiveMessageSound1);
NSString *sendPath2 = [[NSBundle mainBundle] pathForResource:@"Music2" ofType:@"wav"];
            baseURL = (__bridge CFURLRef)[NSURL fileURLWithPath:sendPath2];
            AudioServicesCreateSystemSoundID(baseURL, &receiveMessageSound2);
            AudioServicesPlaySystemSound(receiveMessageSound2);

希望这有帮助。
