iOS 7 MPMoviePlayerController搜索转发按钮将视频带到结束并显示黑屏 [英] iOS 7 MPMoviePlayerController seek forward button brings the video to the End and displays Black screen

问题描述

我在iOS 7中遇到MPMoviePlayerController的问题。我进入全屏，然后在搜索转发按钮（>> |）上单击（只需点击一下），视频播放结束并给出带有文本的黑屏标题上的正在加载。

I am facing an issue with MPMoviePlayerController in iOS 7. I enter the fullscreen and then click (just a single tap) on seek forward button (>>|) , and the video playback ends and gives a black screen with a text "Loading" on the header.

我注册了 MPMoviePlayerPlaybackStateDidChangeNotification 的通知。

**[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(moviePlayerPlaybackStateDidChange:)
                                                 name:MPMoviePlayerPlaybackStateDidChangeNotification
                                               object:self.player];**

它不会被解雇单击向前搜索按钮。

It does not get fired on a single click of seek forward button.

同时注册 MPMoviePlayerPlaybackDidFinishNotification

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

我得到 MPMovieFinishReasonPlay backEnded 事件在单击向前搜索按钮时触发。
任何人都知道原因吗？这是苹果中的一个错误吗？

I get "MPMovieFinishReasonPlaybackEnded" event fired on that single click of seek forward button. Any one knows the reason why? Is this a bug in apple?

我需要停止这种在单击时显示黑屏的行为，或者只是禁用单击向前搜索按钮以便不显示任何内容发生。

I need to either stop this behavior of showing a black screen on single click , or just disable single click of seek forward button so that nothing happens.

任何人都知道如何实现这个目标吗？

Any one knows how to achieve this?

推荐答案

单击快进或快退按钮时，将调用MPMoviePlayerLoadStateDidChangeNotification。你应该检查一下loadState，然后再给它一个你的视频和prepareToPlay的路径。

MPMoviePlayerLoadStateDidChangeNotification will be called when you single tap on the fast-forward or rewind button. You should check the loadState and just give it the path to your video and prepareToPlay again.

- (void)moviePlayerLoadStateChanged:(NSNotification *)notification {

    MPMoviePlayerController *moviePlayer = notification.object;
    MPMovieLoadState loadState = moviePlayer.loadState;

    if(loadState == MPMovieLoadStateUnknown) {
        moviePlayer.contentURL = [NSURL fileURLWithPath:videoPath]
        [moviePlayer prepareToPlay];
    }

    .....
}
