我在iOS 7中面临MPMoviePlayerController的问题.我进入全屏,然后在寻找前进按钮(>> |)上单击(只需点一下),视频播放结束,并给出一个带有文本“加载“标题.
我注册了“MPMoviePlayerPlaybackStateDidChangeNotification”的通知.
**[[NSNotificationCenter defaultCenter] addobserver:self
selector:@selector(moviePlayerPlaybackStateDidChange:)
name:MPMoviePlayerPlaybackStateDidChangeNotification
object:self.player];**
只需点击一下寻找前进按钮就不会被解雇.
还注册了“MPMoviePlayerPlaybackDidFinishNotification”
**[[NSNotificationCenter defaultCenter] addobserver:self
selector:@selector(moviePlayerPlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];**
我获得“MPMovieFinishReasonPlaybackEnded”事件触发了单击寻找前进按钮.
任何人都知道为什么？这是苹果的错误吗？
我需要停止这种单击时显示黑色屏幕的行为,或者只是禁用单击“寻找前进”按钮,这样就不会发生任何事情.
任何人都知道如何实现这一点？
解决方法
我通过完全删除MPMoviePlayer对象来修复此问题,将其设置为nil,将其从超级视图中删除,并使用原始视频Url重新添加.代码如下：
- (void)addplayerForUrl:(NSURL *)url {
self.player = [[MPMoviePlayerController alloc] initWithContentURL:url];
self.player.view.frame = self.videoView.bounds;
self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.player.controlStyle = MPMovieControlStyleDefault;
[self.videoView insertSubview:self.player.view atIndex:0];
[[NSNotificationCenter defaultCenter] addobserver:self
selector:@selector(moviePlayerLoadStateDidChangednotification:)
name:MPMoviePlayerReadyFordisplayDidChangeNotification
object:self.player];
[[NSNotificationCenter defaultCenter] addobserver:self
selector:@selector(moviePlayerPlaybackStateDidChangeNotification:)
name:MPMoviePlayerPlaybackStateDidChangeNotification
object:self.player];
}
#pragma mark - Notifications
- (void)moviePlayerLoadStateDidChangednotification:(NSNotification *)notification {
self.isVideoPreloaded = YES;
self.videoPlayButton.hidden = YES;
self.photoImageView.hidden = YES;
self.videoLoadingImageView.hidden = YES;
}
- (void)moviePlayerPlaybackStateDidChangeNotification:(NSNotification *)notification {
NSURL *url = self.player.contentURL;
switch (self.player.playbackState) {
case MPMoviePlaybackStateSeekingBackward:
case MPMoviePlaybackStateSeekingForward:
break;
case MPMoviePlaybackStatePlaying:
self.videoPlayButton.hidden = YES;
if (!self.isVideoPreloaded) {
self.videoLoadingImageView.hidden = NO;
[self.videoLoadingImageView startAnimating];
} else {
self.videoLoadingImageView.hidden = YES;
}
break;
case MPMoviePlaybackStatePaused:
case MPMoviePlaybackStateStopped:
self.videoPlayButton.hidden = NO;
self.videoLoadingImageView.hidden = YES;
[self.player endSeeking];
[self.player.view removeFromSuperview];
[self.player setFullscreen:NO];
self.player = nil;
[self addplayerForUrl:url];
break;
default:
break;
}
}
注意我如何保持NSURL,就在moviePlayerPlaybackStateDidChangeNotification中的switch语句之前.这样,我可以重新初始化并重新添加MPMoviePlayer对象.
Btw,我的mpmovieplayer是在tableviewCell,如果你想知道.希望这有帮助,让我知道如果你有问题.祝你好运！
