MPMoviePlayer 控制器不播放视频答案

【问题描述】：

我正在开发一个需要使用 Xcode 4.5.2 和 iOS 6.0 播放视频的应用。

我正在使用 MPMoviePlayerController 播放视频。我关注了this tutorial。但是，我仍然无法在模拟器中播放视频。

这是我的代码：

- (IBAction)playVideo:(id)sender {
 NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"Movie-1" ofType:@"mp4"];
 NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
 MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
 moviePlayerController.shouldAutoplay =YES ;
 moviePlayerController.controlStyle = MPMovieControlStyleDefault ;
 moviePlayerController.scalingMode = MPMovieScalingModeFill ;
 [moviePlayerController.view setFrame:CGRectMake(0, 0, 360, 200)];
 [self.view addSubview:moviePlayerController.view];
 [[NSNotificationCenter defaultCenter] addObserver:self
                                          selector:@selector(moviePlaybackComplete:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayerController];
[moviePlayerController play ] ;

}

- (void)moviePlaybackComplete:(NSNotification *)notification
{
    MPMoviePlayerController *moviePlayerController = [notification object];
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:moviePlayerController];

    [moviePlayerController.view removeFromSuperview];
}

我已经看过很多 SO 问题，但没有一个能解决我的问题。我还尝试创建一个 containerView 并将我的 MPMoviePlayerController添加到我的 containerView 中。我没有让它工作。

我也试过MPMoviePlayerViewController，到目前为止我能够让它工作。另一个问题，我不能setFrame 到MPMoviePlayerViewController。但是，我想将 setFrame 设置为我的视频播放器。它的大小不可能是全屏的。因为，我需要在我的视频播放器下方显示一些按钮。

你们知道我该怎么做吗？

【问题讨论】：

添加 [moviePlayerController prepareToPlay ] ; [moviePlayerController 播放]之前；如果它不起作用，请检查文件的路径
我已经尝试过prepareToPlay方法，它没有效果，只是两次控制台输出。文件路径也正确。

【解决方案1】：

我终于完成了这项工作。在 iOS 5.0 之后，MPMoviePlayerController 需要声明为属性。因此，我将其添加为属性并且它起作用了。

【讨论】：

没有声明的属性你可以使用它:)

【解决方案2】：

你能试试这个代码吗：

MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:_urlToLoad];
[self presentModalViewController:mp animated:YES];

而不是：

[self.view addSubview:moviePlayerController.view];

希望这会有所帮助。干杯。

【讨论】：

不可能，如果我这样做，应用程序将崩溃，因为你不能将moviePlayerController作为参数提供给presentModalViewController。测试，崩溃
哦，我明白了，因为您使用的是 MPMoviePlayerController 而不是 MPMoviePlayerViewController，所以它对我的答案不起作用。我将编辑我的答案。最好的。
你可以试试 MPMoviewPlayerController 吗？我用这个类来处理 youtube 视频，这对我来说很好。希望它能有所帮助。
谢谢，我找到了解决方案并在我的回答中进行了解释。教程很旧，所以这就是问题所在。 MPMoviePlayerController 需要声明为属性。
