MPMoviePlayerController:播放器仅在打击iOS6时永久隐藏播放器控件

Question

MPMoviePlayerController播放器在按下完成按钮后永久隐藏播放器控件.

我有一个带有moviePlayer.controlStyle = MPMovieControlStyleEmbedded的嵌入式播放器,当用户点击moviePlayerDidEnterFullscreen通知中的全屏模式时,我正在制作[moviePlayer setFullscreen:NO]; 并将播放器视频转换为横向模式

moviePlayer.view.transform = CGAffineTransformMakeRotation(degreesToRadians(-90));

和设置

moviePlayer.controlStyle =  MPMovieControlStyleFullscreen; 

然后,当我点击完成按钮并在moviePlayBackDidFinish中,我正在将视图转换回纵向模式并将controlStyle设置为Embedded.到目前为止它的工作正常.之后视频将暂停,当我点按播放按钮时,它开始播放,播放器将停留一段时间并永久隐藏.播放视频后播放器不再可见.我试图在延迟后将播放器控制设置为嵌入式.但没有任何工作.请帮忙解决这个问题.

此问题仅适用于iOS 6以下的版本

if (mpVideoPlayerController)

}


mpVideoPlayerController = nil;
mpVideoPlayerController = [[VideoPlayerViewController alloc] initWithContentURL: theURL];

                     } completion:^(BOOL finished) {

                     }];


}

- (void) setControlStyleFullscreen 
         mpVideoPlayerController.moviePlayer.controlStyle =  MPMovieControlStyleFullscreen;

- (void) setControlStyleEmbedded 

        mpVideoPlayerController.moviePlayer.controlStyle =  MPMovieControlStyleEmbedded;



- moviePlayBackDidFinish:

    NSLog(@"moviePlayBackDidFinish:");

    [self rotateToInterfaceOrientation:UIInterfaceOrientationPortrait frameForView:(viewController).videoContentView.frame];

    [[UIApplication sharedApplication] setStatusBarHidden:NO];

    [self performSelector:@selector(setControlStyleEmbedded) withObject:nil afterDelay:0.2];

您的代码有问题并会触发这些MPMoviePlayerController错误。

• 多余的 setFullscreen 因为我们已经处于全屏状态。
• 多余的 setControlStyle 因为我们已经处于全屏控制样式

一般来说，你不应该在 MPMoviePlayerController 上强制执行已经完成的事情。

- (void)moviePlayerDidEnterFullscreen :(NSNotification*)notification 
{
    //
    //remove both lines from this notification handler
    //
    [mpVideoPlayerController.moviePlayer setFullscreen:NO];
    [self performSelector:@selector(setControlStyleFullscreen) withObject:nil afterDelay:0.2];
    [...]
} 

您还可以通过检查当前模式来扩展 setControlStyleFullscreen / Embedded 实现。这可能看起来很奇怪，但确实有很大帮助。

- (void)setControlStyleEmbedded
{
    if (mpVideoPlayerController.moviePlayer.controlStyle != MPMovieControlStyleEmbedded)
    {
        mpVideoPlayerController.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
    }
}

- (void)setControlStyleFullscreen
{
    if (mpVideoPlayerController.moviePlayer.controlStyle != MPMovieControlStyleFullscreen)
    {
        mpVideoPlayerController.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
    }
}
