不能暂停循环，因为的MPMoviePlayerController

Question

错误的电影，我成立了电影播放这样的：

self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:@"whatever.mp4"]; 
    self.moviePlayer.controlStyle = MPMovieControlStyleNone; 
    self.moviePlayer.shouldAutoplay = YES; 
    [self.moviePlayer prepareToPlay]; 
    self.moviePlayer.repeatMode = MPMovieRepeatModeOne; 
    self.moviePlayer.view.frame = self.container.bounds; 
    self.moviePlayer.view.userInteractionEnabled = NO; 
    [self.container addSubview:self.moviePlayer.view]; 

    [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(moviePlayBackDidFinish:) name: MPMoviePlayerPlaybackStateDidChangeNotification 
               object: self.moviePlayer]; 

的通知是必要的，以保持玩家的循环，因为REPEATMODE是几乎无用的（视频会重复一次或两次，也许几次取决于中国大米的价格，然后停止）。所以要保持视频循环，你必须这样做：

- (void)moviePlayBackDidFinish:(NSNotification *)note { 
    if (note.object == self.moviePlayer) { 
     NSInteger reason = [[note.userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue]; 
     if (reason == MPMovieFinishReasonPlaybackEnded) { 
      [self.moviePlayer play]; 
     } 
    } 
} 

现在的问题是，我需要能够暂停视频。出于某种原因，到

[self.moviePlayer pause]; 

结果通知调用与理由解雇== MPMovieFinishReasonPlaybackEnded即使文档中明确指出这一点：

Constants 
MPMovieFinishReasonPlaybackEnded 
The end of the movie was reached. 
Available in iOS 3.2 and later. 
Declared in MPMoviePlayerController.h. 

在电影的结尾没有达到。我只是叫暂停：。所以通知被触发，因此电影再次播放，否定了暂停动作。

所以你可以看到问题。如何成功暂停循环视频？

Answer 1

在你的类中创建一个BOOL并初始化为NO，

@property (nonatomic, assign) BOOL isTriggeredByPause; 

调用

[self.moviePlayer pause]; 

将其值设置之前，

self.isTriggeredByPause = YES; 

在它的方法检查

，

(void)moviePlayBackDidFinish:(NSNotification *)note { 
if (note.object == self.moviePlayer) { 
    NSInteger reason = [[note.userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue]; 
    if (reason == MPMovieFinishReasonPlaybackEnded) { 
if(!self.isTriggeredByPause) 
{ 
    [self.moviePlayer play]; 
} 
} 
} 
} 

修改self.isTriggeredByPause在手动播放时的值，否则循环不起作用。
