找出MPMoviePlayerController是否正在播放

我有关于MPMoviePlayerController的一个小问题，我有一个链接，播放电影，当我点击该电影button，但是当我点击另一个button应用程序崩溃，我需要find如何确定电影播放或获得任何forms的回应

Answer 1

要扩大@ Saurabh的答案，你可以检查video是否正在播放

if(player.playbackState == MPMoviePlaybackStatePlaying) { // is Playing } 

MPMoviePlaybackState被定义为

 enum { MPMoviePlaybackStateStopped, MPMoviePlaybackStatePlaying, MPMoviePlaybackStatePaused, MPMoviePlaybackStateInterrupted, MPMoviePlaybackStateSeekingForward, MPMoviePlaybackStateSeekingBackward }; typedef NSInteger MPMoviePlaybackState; 

Answer 2

有两个部分，通常组合使用;

像这样注册MPMoviePlayerPlaybackStateDidChangeNotification ：

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(MPMoviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil]; 

在通知处理程序中，您可以详细检查实际状态 – 例如：

 - (void)MPMoviePlayerPlaybackStateDidChange:(NSNotification *)notification { //are we currently playing? if (movieController_.playbackState == MPMoviePlaybackStatePlaying) { //yes->do something as we are playing... } else { //nope->do something else since we are not playing } } 

您当然也可以使用playbackState属性，而不处理发出信号更改的通知。 尽pipe如此，在大多数情况下，这是正确的。

当删除/杀死你的电影播放时，不要忘记删除通知处理程序，例如像这样：

 [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; 

Answer 3

您可以检查MPMoviePlayerController的playbackState属性。 参考这个链接 –

Answer 4

迅速实现@ ZKV7的答案是：

 if(player.playbackState == MPMoviePlaybackState.Playing) { // is Playing } 

其中MPMoviePlaybackState枚举是：

 enum MPMoviePlaybackState : Int { case Stopped case Playing case Paused case Interrupted case SeekingForward case SeekingBackward }

Answer 5

检查video播放器是否处于播放状态或不在SWIFT中

 @IBAction func btnPressPlay(sender: AnyObject) { if videoPlayerViewController.moviePlayer.playbackState == MPMoviePlaybackState.Playing { self.videoPlayerViewController.moviePlayer.stop() } else { self.videoPlayerViewController.moviePlayer.play() } } 

Answer 6

 typedef NS_ENUM(NSInteger, AVPlayerTimeControlStatus) { AVPlayerTimeControlStatusPaused, AVPlayerTimeControlStatusWaitingToPlayAtSpecifiedRate, AVPlayerTimeControlStatusPlaying } NS_ENUM_AVAILABLE(10_12, 10_0); if(self.player.timeControlStatus == AVPlayerTimeControlStatusPlaying) { // is Playing }
