我使用AVAudioPlayer(不是AVPlayer)实现了一个音频播放器.我可以使用以下方法处理远程控制事件.它的工作原理相当好的,到目前为止,但是我看到两个以上subtypes这些事件:UIEventSubtypeRemoteControlEndSeekingForward和UIEventSubtypeRemoteControlEndSeekingBackward.

- (void)remoteControlReceivedWithEvent:(UIEvent *)event {
    //if it is a remote control event handle it correctly
    if (event.type == UIEventTypeRemoteControl)
    {
        if (event.subtype == UIEventSubtypeRemoteControlPlay)
        {

        {
            [self pauseAudio];
        }
        else if (event.subtype == UIEventSubtypeRemoteControlTogglePlayPause)
        {
            [self togglePlayPause];
        }
        else if (event.subtype == UIEventSubtypeRemoteControlBeginSeekingBackward)
        {
            [self rewindTheAudio]; //this method rewinds the audio by 15 seconds.
        }
        else if (event.subtype == UIEventSubtypeRemoteControlBeginSeekingForward)
        {
            [self …
