的MPMoviePlayerController - 黑色畫面切換時的觀點

背景圖像是動畫天空的MPMoviePlayerController - 黑色畫面切換時的觀點

當設置頁面（靜態圖像）和主頁（動畫圖像）的屏幕的動畫經常脫落，併成爲一個單一的黑色圖像之間的切換

有人可以提出一個理由或解決方案嗎？

謝謝！

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    self.mp = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"iPhone4" ofType:@"mov"]]]; 
    mp.repeatMode = MPMovieRepeatModeOne; 
    [mp.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; 
    mp.scalingMode = MPMovieScalingModeFill; 
    [mp setFullscreen:YES]; 
    mp.controlStyle = MPMovieControlStyleNone; 
    [self.view addSubview:mp.view]; 
    [self.view sendSubviewToBack:mp.view]; 
    [mp prepareToPlay]; 
} 

- (void)viewWillAppear:(BOOL)animated 
{ 
    [super viewWillAppear:animated]; 

    [self.mp play]; 
}

嘗試觀察者添加到您的播放器。就像這樣：

- (void)viewDidLoad 
{ 
    ///... 
    self.mp = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"iPhone4" ofType:@"mov"]]]; 
    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(moviePlaybackComplete:) 
               name:MPMoviePlayerPlaybackDidFinishNotification 
              object:self.mp]; 
    ///... 
}

然後你就可以得到了什麼問題：

- (void)moviePlaybackComplete:(NSNotification *)notification 
{ 
    NSLog(@"Movie Finished."); 

    int reason = [[[notification userInfo] valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue]; 
    if (reason == MPMovieFinishReasonPlaybackError) { 
     NSDictionary *notificationUserInfo = [notification userInfo]; 
     NSError *mediaPlayerError = [notificationUserInfo objectForKey:@"error"]; 
     if (mediaPlayerError) 
     { 
     NSLog(@"playback failed with error description: %@", [mediaPlayerError localizedDescription]); 
     } 
     else 
     { 
     NSLog(@"playback failed without any given reason"); 
     } 
    }  

    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:self.mp];

}
