如何在iphone应用程序中播放来自http url的视频

Question

我想在iphone app中播放来自网址的视频，但是我在使用以下代码的应用中无法播放

-(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

看起来像这样：

NSURL *videoURL = [NSURL fileURLWithPath:videoFilepath];

你的问题。您的“http：//”样式网址不是文件网址。文件URL（在本地设备/文件系统上）以“file:///”开头。

尝试：

NSURL * videoURL = [NSURL URLWithString: videoFilepath];

看看它是否更好。

Answer 2

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];
