MPMoviePlayerViewController隐藏状态栏

Question

我有一个iPad应用程序,用于创建和显示视频MPMoviePlayerViewController.这是我的代码:

MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:URLEncode(uri)]];
[mpvc setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[mpvc setWantsFullScreenLayout:YES];
[<MainViewController> presentModalViewController:mpvc animated:YES];

电影加载/播放工作正常,但是,当电影控制器出现时,它会在顶部显示状态栏(连接,电池,小时),即使我在主窗口上取消激活它也是如此.

我试过做:

[mpvc setWantsFullScreenLayout:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES];

似乎没有任何工作,但是如果我也放了:

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];

状态栏消失了!但电影控制器仍然会调整大小,好像状态栏在那里(即使我已经使用过-setWantsFullScreenLayout:).

有人能指出一种简单(经过验证)的方式来显示没有状态栏的视频吗？

谢谢.

刚刚意识到这个问题是针对 iPad 的。我的代码是针对 iPhone 的，但其中一些代码可能会对您有所帮助。

几天前我不得不这样做，我认为你的问题只是在视频开始播放后没有在状态栏上调用隐藏。不管怎样，我这里有经过尝试和测试的代码，它可以在 3.0 到 4.2 之间运行：

- (IBAction) playIntroVideo
{
    NSString *videoString = [[NSBundle mainBundle] pathForResource:@"intro" ofType:@"mp4"];
    NSURL *videoURL = [NSURL fileURLWithPath:videoString];
    _player = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];

    if
    (
        [_player respondsToSelector:@selector(view)] &&
        [_player respondsToSelector:@selector(setFullscreen:animated:)] &&
        [_player respondsToSelector:@selector(setControlStyle:)]
    )
    {
        [[_player view] setFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT_FULL)];
        [_player setFullscreen:YES animated:YES];
        [_player setControlStyle:MPMovieControlStyleNone];
        [self.view addSubview:[_player view]];
    }

    [_player play];

    [[NSNotificationCenter defaultCenter]
     addObserver:self
     selector:@selector(terminateVideo)
     name:MPMoviePlayerPlaybackDidFinishNotification
     object:nil];   

    [[UIApplication sharedApplication] setStatusBarHidden:YES];
    self.navigationController.navigationBarHidden = YES;
}

- (void) terminateVideo
{
    [[UIApplication sharedApplication] setStatusBarHidden:NO];
    self.navigationController.navigationBarHidden = NO;

    if ([_player respondsToSelector:@selector(view)])
    {
        [[_player view] removeFromSuperview];   
    }

    _player = nil;
    [_player release];
}
