iOS 7视频未播放

Question

我使用MPMoviePlayerController播放视频，但这只显示黑屏。没有播放我的视频。这段代码是对的。哪里可能我错了....

我已经完成了这段代码来播放视频..

    NSString * str=[[NSBundle mainBundle]pathForResource:@"iGreet" ofType:@"m4v"];
    NSURL * url=[NSURL fileURLWithPath:str];
    MPMoviePlayerController * movieController=[[MPMoviePlayerController alloc]initWithContentURL:url];
    movieController.controlStyle=MPMovieControlStyleFullscreen;
    [movieController.view setFrame:self.view.bounds];
    [self.view addSubview:movieController.view];
    [movieController prepareToPlay];
    [movieController play];

任何帮助表示赞赏.. 提前谢谢..

Answer 1

如果您尝试从资源播放视频，则需要提及：

   [movieController setMovieSourceType:MPMovieSourceTypeFile];

Answer 2

这是我的代码。我有一个按钮，可以为我的视频显示图像。

@property (nonatomic,strong) MPMoviePlayerController* moviePlayer;

将此添加到您的.h文件中。

  

NSURL * url = [NSURL URLWithString：                     @ “http://www.mydomain/video/1.mp4”];

_moviePlayer =  [[MPMoviePlayerController alloc]
                 initWithContentURL:url];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:_moviePlayer];
CGRect frame = _btnVideo.frame;
[_moviePlayer.view setFrame:frame];
_moviePlayer.controlStyle = MPMovieControlStyleDefault;
_moviePlayer.shouldAutoplay = YES;
[self.view addSubview:_moviePlayer.view];
[_moviePlayer setFullscreen:NO animated:YES];

Answer 3

根据documentation，未提及.m4v扩展名。

Answer 4

我确实喜欢这个并且工作正常：

NSString *videoFileName = [[NSBundle mainBundle] pathForResource:videoName ofType:@"m4v" inDirectory:nil];

self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL: [NSURL fileURLWithPath:videoFileName]];
[self.moviePlayerController setShouldAutoplay:YES];
[self.moviePlayerController prepareToPlay];
[self.moviePlayerController setFullscreen:NO];
[self.moviePlayerController.view setFrame:self.infoViewController.view.bounds];
[self.view addSubview:self.moviePlayerController.view];
[self.moviePlayerController play];
