MPMoviePlayerController - 检测按下Next/Prev按钮

Question

我正在使用MPMoviePlayerController,我需要检测按下Next/Prev按钮.我尝试了几件事,但似乎都没有.

这是我尝试过的:

• 遥控事件

-(void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    [self becomeFirstResponder];
}  
-(void) viewWillDisappear:(BOOL)animated
{
    [[UIApplication sharedApplication] endReceivingRemoteControlEvents];
    [self resignFirstResponder];
    [super viewWillDisappear:animated];
}  
-(BOOL)canBecomeFirstResponder
{
    return YES;
}  
-(void)remoteControlReceivedWithEvent:(UIEvent *)receivedEvent
{
    // stuff
}

问题是remoteControlReceivedWithEvent方法永远不会被调用.我已经读过,这在iOS版本高于6时无效 - 我正在iOS 7上工作

• 通知

我尝试使用MPMoviePlayerPlaybackStateDidChangeNotification并检查MPMoviePlaybackStateSeekingForward或者MPMoviePlaybackStateSeekingBackward- 不幸的是,拖动播放栏时设置了这些播放状态,而不是按下"下一个/上一个"按钮时.

有任何想法吗？

抱歉，我不太了解您的问题，但是如果您想在控制中心使用应用程序的控件，您可以使用：

\n\n

      // You need cath the singleton\nMPRemoteCommandCenter *myRemote = [MPRemoteCommandCenter sharedCommandCenter];\n//And add the selector you can fire depends on the button, a couple of examples:\n[myRemote.playCommand addTarget:self action:@selector(myPlayMethods)];\n[myRemote.nextTrackCommand addTarget:self action:@selector(myNextTrackMethods)];\n

\n
