如何在iphone应用程序中播放来自htp url的视频

Question

我想在iphone应用程序中播放来自url的视频，但它在应用程序中不播放，我使用以下代码

-(IBAction)play
{
     NSString*videoFilepath=@"http://myserver.com.pk/Specticle_Revision_v1.mov";
     NSLog(@"Filepath is: %@", videoFilepath);
     NSURL *videoURL = [NSURL fileURLWithPath:videoFilepath];   
     MPMoviePlayerController *movie = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:movie];
     [movie play];
}

Answer 1

这样做：

NSURL *url = [NSURL URLWithString:@"http://myserver.com.pk/Specticle_Revision_v1.mov"];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
                                 selector:@selector(moviePlaybackDidFinish:)
                                     name:MPMoviePlayerPlaybackDidFinishNotification
                                   object:mp];    
mp.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
[self presentMoviePlayerViewControllerAnimated:mp];
[mp release];

Answer 2

看起来像这样：

NSURL *videoURL = [NSURL fileURLWithPath:videoFilepath];

是你的问题。您的"http://"样式URL不是文件URL。文件URL（在本地设备/文件系统上）以"file:///"开头。

尝试：

NSURL * videoURL = [NSURL URLWithString: videoFilepath];

看看效果是否更好。
