ipad – MPMoviePlayerViewController隐藏状态栏

我有一个iPad应用程序创建和显示与MPMoviePlayerViewController的视频.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,它会显示顶部的状态栏(连接,电池,小时),即使我在主窗口中停用了它.

我试过：

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

没有什么似乎工作,不过如果我也放：

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];

状态栏消失！但是电影控制器仍然会像状态栏那样调整大小(即使我已经使用了-setWantsFullScreenLayout :).

有人可以指出一个简单(经过验证)的方式来显示没有状态栏的视频吗？

谢谢.

解决方法

只是意识到这个问题是iPad特有的.我的代码是针对iPhone,但有些可能会帮助你.

几天前我不得不这样做,我认为你的问题在视频开始播放后根本就不会在状态栏上调用隐藏.无论哪种方式,我都有经过验证的代码,其工作范围为3.0到4.2：

- (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,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];
}
