如何從HTP網址在iPhone應用程序播放視頻

Question

我想在iphone應用程序從URL播放視頻，但它並沒有在應用程序中扮演我用下面的代碼

-(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

這樣做：

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

如下：

NSURL *videoURL = [NSURL fileURLWithPath:videoFilepath]; 

是你的問題。您的「http：//」樣式的網址不是文件網址。文件URL（在本地設備/文件系統上）以「file:///」開頭。

嘗試：

NSURL * videoURL = [NSURL URLWithString: videoFilepath]; 

，看看是否能更好地工作。
