MPMoviePlayerViewController隐藏状态栏

刚意识到这个问题是针对iPad的。我的代码是为iPhone编写的,但有些代码可能会对你有所帮助。

我不得不这样做几天前,我想你的问题只是没有呼吁隐藏状态栏后,视频开始播放。无论哪种方式,我这里都有经过测试的代码,从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, 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];
}

_player = nil;
[_player release];

这些应该颠倒过来:

[_player release];
_player = nil;

发布消息nil无效。

您可以在plist中设置UIStatusBarHidden,这应该可以解决它:)
