我通过使用此代码在 iPhone 中播放视频

-(IBAction)btnNew_clicked:(id)sender {  

NSURL *url = [NSURL URLWithString:@"http://www.businessfactors.de/bfcms/images/stories/videos/defaultscreenvideos.mp4"];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
[[mp moviePlayer] prepareToPlay];
[[mp moviePlayer] setShouldAutoplay:YES];
[[mp moviePlayer] setControlStyle:2];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[self presentMoviePlayerViewControllerAnimated:mp];}

-(void)videoPlayBackDidFinish:(NSNotification*)notification  {       
[self dismissMoviePlayerViewControllerAnimated];  }

通过使用此代码电影播放器打开 1 秒，然后自动关闭，而不播放文件。

我检查了视频文件，它是正确的，但它无法在 iphone sdk 4.0 中播放。

提前致谢。

I played video in iphone by using this code

-(IBAction)btnNew_clicked:(id)sender {  

NSURL *url = [NSURL URLWithString:@"http://www.businessfactors.de/bfcms/images/stories/videos/defaultscreenvideos.mp4"];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
[[mp moviePlayer] prepareToPlay];
[[mp moviePlayer] setShouldAutoplay:YES];
[[mp moviePlayer] setControlStyle:2];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[self presentMoviePlayerViewControllerAnimated:mp];}

-(void)videoPlayBackDidFinish:(NSNotification*)notification  {       
[self dismissMoviePlayerViewControllerAnimated];  }

by using this code movie player opens for 1 second and then close automatically, without playing the file.

I checked the video file it is correct but it is not playing in iphone sdk 4.0.

Thanks in Advance.

请参阅这个问题 -

播放视频在 Iphone 应用程序中从服务器获取文件

尝试以下代码，不要忘记添加 MediaPlayer.framework 并且必须导入


- (void)viewDidLoad {
    [super viewDidLoad];

    NSURL *url = [NSURL URLWithString:@"http://www.businessfactors.de/bfcms/images/stories/videos/defaultscreenvideos.mp4"];
    MPMoviePlayerController *player =[[MPMoviePlayerController alloc] initWithContentURL: url];
    [[player view] setFrame: [self.view bounds]];  // frame must match parent view
    [self.view addSubview: [player view]];
    [player play];

}

please see this question-
