Ios4 iphone sdk按钮声音

我想为按钮添加声音，请帮助我。

您可以使用

UIDevice

类中的方法

-（void）playInputClick

。您可以使用静态方法

+（UIDevice*）currentDevice

访问此类的实例。使用此方法将默认输入声音附加到您自己的自定义UI。

您不能仅复制和粘贴代码。必须使用堆栈溢出的格式选项。请更正。

- (IBAction)startPlayback:(UIButton *)sender {
   
       NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
       resourcePath = [resourcePath stringByAppendingString:@"/grabbag.m4a"];
       NSLog(@"Path to play: %@", resourcePath);
       NSError* err;

     
       player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:resourcePath] error:&err];

       if( err ){
           //bail!
           NSLog(@"Failed with reason: %@", [err localizedDescription]);
       }
       else{
           player.delegate = self;
           [player play];
       }
   
}
