MPMoviePlayer完成按鈕單擊更改UIView高度

Question

我正在使用MPMoviePlayer來顯示視頻。我進入全屏，當完成按鈕被點擊時，我希望它從我的視圖中移除整個電影播放器​​。

現在當我點擊完成按鈕它關閉MPMoviePlayer但它改變了我的UIView高度的大小。有沒有解決方案刪除MPMoviePlayer而不影響我的視圖大小。

創建一個videoPlayer視圖控制器（MPMoviePlayerViewController子類）並將其添加到您的根視圖控制器。

videoPlayerViewController = [[VideoViewController alloc] initWithContentURL:[NSURL fileURLWithPath:resourcePath]]; 
[rootViewController presentMoviePlayerViewControllerAnimated:videoPlayerViewController]; 
videoPlayer.controlStyle = MPMovieControlStyleFullscreen; 

然後添加通知：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stopVideo:) name:MPMoviePlayerPlaybackDidFinishNotification object:[videoPlayerViewController moviePlayer]]; 
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stopVideo:) name:MPMoviePlayerDidExitFullscreenNotification object:[videoPlayerViewController moviePlayer]];       

那麼你的方法收到通知時調用。

- (void) stopVideo:(NSNotification*) aNotification { 
    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:[videoPlayerViewController moviePlayer]]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerDidExitFullscreenNotification object:[videoPlayerViewController moviePlayer]]; 
    MPMoviePlayerController *player = [aNotification object]; 
    [player stop]; 
}
