标题: ios - 如何使状态栏在 iOS 的 MPMoviePlayerController 中不消失？

在 MPMoviePlayerController 中，当控件消失时，甚至状态栏也会随之消失。由于我希望即使控件消失也能显示状态栏，所以我放置了以下代码

[[UIApplication sharedApplication] setStatusBarHidden:NO]; 但是上面的代码没有任何区别，状态栏随着播放器控件消失。如何解决这个问题呢。

请找到下面的代码，并告诉我如何纠正它。

- (void) readyPlayer {

 mp =  [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
 if ([mp respondsToSelectorselector(loadState)]) 
    {
        // Set movie player layout
        [mp setControlStyle:MPMovieControlStyleFullscreen];
        [mp setFullscreen:YES];

    // May help to reduce latency
    [mp prepareToPlay];

    // Register that the load state changed (movie is ready)
         [[NSNotificationCenter defaultCenter] addObserver:self selectorselector(moviePlayerLoadStateChanged name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
       } else {
        [[NSNotificationCenter defaultCenter] addObserver:self selectorselector(moviePreloadDidFinish name:MPMediaPlaybackIsPreparedToPlayDidChangeNotification 
                                                   object:nil];
       }
    // Register to receive a notification when the movie has finished playing. 
    [[NSNotificationCenter defaultCenter] addObserver:self selectorselector(moviePlayBackDidFinish name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
}

- (void) moviePlayerLoadStateChangedNSNotification*)notification {

    NSLog(@"moviePlayerLoadStateChanged");
    // Unless state is unknown, start playback
    if ([mp loadState] != MPMovieLoadStateUnknown)
      {
  // Remove observer
    [[NSNotificationCenter  defaultCenter] removeObserver:self  name:MPMoviePlayerLoadStateDidChangeNotification 
                                object:nil];
      [[UIApplication sharedApplication] setStatusBarHidden:NO];

      // Rotate the view for landscape playback
     [[self view] setBounds:CGRectMake(0, 0, 768, 1000)];

      // Set frame of movieplayer
       [[mp view] setFrame:CGRectMake(0, 0, 768, 1000)];

    // Add movie player as subview
    [[self view] addSubview:[mp view]];   

    // Play the movie
    [mp play];
   }
}

- (void) moviePreloadDidFinishNSNotification*)notification {
    // Remove observer
    NSLog(@"moviePreloadDidFinish");
    [[NSNotificationCenter  defaultCenter] removeObserver:nil   
                                                     name:MPMediaPlaybackIsPreparedToPlayDidChangeNotification 
                                                   object:nil];

    [[UIApplication sharedApplication] setStatusBarHidden:NO];
    // Play the movie
    [mp play];
}

- (void) moviePlayBackDidFinishNSNotification*)notification {    
    NSLog(@"moviePlayBackDidFinish");
    [[UIApplication sharedApplication] setStatusBarHidden:NO];
    // Remove observer
  [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification 
                            object:nil];
    [self dismissModalViewControllerAnimated:YES];  
}

Best Answer-推荐答案

这是一个众所周知的 MPMovieControlStyleFullscreen 问题。只需使用 MPMovieControlStyleEmbedded controlStyle 就可以了。

顺便说一句，对于嵌入式使用来说，这就是更合适的 controlStyle。
