所以我有一个 UITableViewController 推送一个 UIViewController ，其中有一个 MPMoviePlayer 对象。我发现当我将 MPMoviePlayer 作为子视图加载时，它会创建一个状态栏。此状态栏将导航栏向下推到顶部，从而产生空白。我在 stackoverflow 上查看了一堆不同的主题，但似乎没有任何效果：

iPhone：UINavigationController 顶部的奇怪空间

不知道为什么 UIView 被推高了大约 10px

从全屏模式关闭 MPMoviewPlayer 后 UITableView 下的空（白）行

从 MPMoviePlayerController 隐藏状态栏

UIViewController 使用以下代码 (PresetViewController.m) 推送：

-(void)tableView:(UITableView *)tableView 
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSUInteger row = [indexPath row];
    //PresetNode *tempNode = [appDelegate.presetData objectAtIndex:row];

   ..... SOME DATA IS LOADED HERE

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
    MoviePlayer *player = [[MoviePlayer alloc] initWithNibName:nil bundle:nil andVideoArray: presetVideoURLs];
    [self.navigationController pushViewController:player animated:NO];
    [player playVideoAtIndex:0];
    [player release];

[tableView deselectRowAtIndexPath:indexPath animated:YES];
}

当视图控制器加载时，由于某种原因，即使我在 MoviePlayer.m 中使用此代码，它也会加载到其视图顶部的状态栏中：

- (void)viewDidAppear:(BOOL)animated{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[super viewDidAppear:animated];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];
}

我将电影设置为横向模式并播放。然后我检查是否按下了完成按钮。如果按下完成按钮，我会弹出视图。出于某种原因，当视图被弹出时，它后面的 uitableviewcontroller 会被向下推几个像素。电影播放器​​创建的状态栏将所有内容向下推。这是电影播放器​​代码（MoviePlayer.m）：

-(void) playVideoAtIndex: (NSInteger)index{

NSString *rootPath = [[NSBundle mainBundle] resourcePath];
NSString *filePath = [rootPath stringByAppendingPathComponent: [self.movieArray objectAtIndex:index]];
NSURL *fileURL = [NSURL fileURLWithPath:filePath isDirectory:NO];
self.yourMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: fileURL];

[yourMoviePlayer setControlStyle:MPMovieControlStyleFullscreen];



[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
[[UIApplication sharedApplication] setStatusBarHidden:YES];

[[self navigationController] setNavigationBarHidden: YES];

yourMoviePlayer.scalingMode = MPMovieScalingModeFill;
[[yourMoviePlayer view] setTransform:CGAffineTransformMakeRotation(M_PI/2)];
self.yourMoviePlayer.view.frame = self.view.frame;

[yourMoviePlayer setFullscreen:YES animated:NO];

[[NSNotificationCenter defaultCenter] 
 addObserver:self
 selector:@selector(checkForNextMovie:)                                                 
 name:MPMoviePlayerPlaybackDidFinishNotification
 object:yourMoviePlayer];

[[self view]addSubview:yourMoviePlayer.view];
//[[self navigationController] presentMoviePlayerViewControllerAnimated:self];
//---play movie---
[yourMoviePlayer play];    

}

-(void) checkForNextMovie:(NSNotification*) aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter] 
 removeObserver:self
 name:MPMoviePlayerPlaybackDidFinishNotification
 object:player];

NSNumber *reason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];

[yourMoviePlayer release];
if((currentIndex+1) == [self.movieArray count] || [reason intValue] == MPMovieFinishReasonUserExited){
    [[NSNotificationCenter defaultCenter] removeObserver:self];
    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
    [player.view removeFromSuperview];
    [[self navigationController] setNavigationBarHidden: NO];
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
    //self.wantsFullScreenLayout = YES;

    [[self navigationController] popViewControllerAnimated:NO];
    if ([UIApplication sharedApplication].statusBarOrientation != self.interfaceOrientation) {
        [[UIApplication sharedApplication] setStatusBarOrientation:self.interfaceOrientation animated:NO];
    }
}
else{
    currentIndex++;
    [self playVideoAtIndex: currentIndex];
}
}

尝试将 viewController.view 的框架（viewController.view.frame）设置为占据整个屏幕的 CGRect：

viewController.view.frame = CGRectMake( 0, 0, 320, 480);

手动设置大小应该可以消除空白。
