MPMoviePlayerController全屏模式问题 [英] MPMoviePlayerController fullscreen mode issue

问题描述

我的代码播放视频文件时遇到问题。每当我以全屏模式播放文件时，播放都不会占用我的所有屏幕。以下是相关代码：

I have a problem with my code that plays a video file. Whenever I play the file in fullscreen mode the playback doesn't occupy all of my screen. Here is the relevant code:

     NSURL *url = [NSURL fileURLWithPath:@"Somefile.mov"];
     moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
    [moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
    [moviePlayer setFullscreen:YES];
    moviePlayer.view.frame = self.switchView.frame;
    [self.switchView addSubview:moviePlayer.view];

    [[NSNotificationCenter defaultCenter] 
    addObserver:self
    selector:@selector(movieFinishedCallback:)                                                 
    name:MPMoviePlayerPlaybackDidFinishNotification
    object:moviePlayer];

    [[NSNotificationCenter defaultCenter] 
     addObserver:self
     selector:@selector(playbackStateDidChange:)                                                 
     name:MPMoviePlayerPlaybackStateDidChangeNotification
     object:moviePlayer];

    [moviePlayer prepareToPlay];
    [moviePlayer play];

这是我得到的输出：

推荐答案

选项A：改为使用 MPMovieViewController 并使用 presentMoviePlayerViewControllerAnimated：以模态方式显示它。

Option A: Use the MPMovieViewController instead and display it modally using presentMoviePlayerViewControllerAnimated:.

选项B：确保你的switchView（你用来添加moviePlayer的视图）实际上占据了整个屏幕。

Option B: Make sure your switchView (which you use for adding the moviePlayer's view to) actually occupies the entire screen.

选项C：使用负垂直偏移重新调整moviePlayer视图的帧，直到它适合 - 例如： moviePlayer.view.frame = CGRectMake（0.0f，-20.0f，320.0f，480.0f）;

Option C: Readjust the frame of the moviePlayer's view with negative vertical offsets until it fits - eg.: moviePlayer.view.frame = CGRectMake(0.0f, -20.0f, 320.0f, 480.0f);

注意：MPMoviePlayerController 始终在使用控件样式时显示状态栏 MPMovieControlStyleFullscreen ，无论你的应用程序的其余部分如何处理状态栏。

Note: MPMoviePlayerController always displays a status bar when using the control style MPMovieControlStyleFullscreen, no matter how the rest of your app handles the status-bar.
