如何播放声音文件“OnTouch”

Question

触摸屏幕时我需要播放文件。

我尝试了以下方法，但它无效：

-(IBAction)play;
{
    CFBundleRef mainBundle = CFBundleGetMainBundle();

    CFURLRef soundFileURLRef;

    soundFileURLRef =CFBundleCopyResourceURL(mainBundle, 
    (CFStringRef) @"sound1", CFSTR ("wav"), NULL);

    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

您是否在窗口或主视图上添加了触控处理程序？

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesBegan:touches withEvent:event];
    [yourObject play];
}
