MPMoviePlayerController iPhone導航欄問題

Question

我有一個視圖控制器，其中包括一個MPMoviePlayer裏面。我隱藏了導航欄，並希望在視頻暫停時顯示它。

當視頻加載時，它工作得很好。在我暫停後，視頻導航欄出現，但它將整個播放器視圖稍微向下。如何讓導航欄出現而不影響播放器視圖。

這裏是我使用的代碼：

在viewDidLoad中（）：

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; 
moviePlayer.controlStyle = MPMovieControlStyleFullscreen; 

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

[self setWantsFullScreenLayout:YES]; 
[moviePlayer prepareToPlay]; 
//For viewing partially..... 
moviePlayer.view.backgroundColor = [UIColor blackColor]; 
//[moviePlayer.view setFrame:CGRectMake(0, 0, 320, 410)]; 
[moviePlayer.view setFrame:[self.view bounds]]; 
moviePlayer.fullscreen = YES; 
moviePlayer.scalingMode = MPMovieScalingModeAspectFill; 

[self.view addSubview:moviePlayer.view]; 

[moviePlayer play]; 

- (void) videoPlayerPlaybackStateChanged:(NSNotification*) aNotification 
{ 
MPMoviePlayerController *player = [aNotification object]; 

if(player.playbackState == MPMoviePlaybackStatePaused){ 

    self.navigationController.navigationBar.tintColor = [UIColor blackColor]; 
    self.navigationController.navigationBarHidden = NO; 

} 
else if(player.playbackState == MPMoviePlaybackStatePlaying){ 
    self.navigationController.navigationBarHidden = YES; 
} 

[player autorelease];  
} 

預先感謝您...

在你的病情

if(player.playbackState == MPMoviePlaybackStatePaused) 
{ 
    self.navigationController.navigationBar.tintColor = [UIColor blackColor]; 
    self.navigationController.navigationBarHidden = NO; 

}

試試吧唱歌

[self.navigationController.navigationBar setTranslucent:YES];
