如何使用html url IOS播放mp4文件

Question

我一直在尝试播放mp4文件，我从服务器接收网址，我已经将其提供给MPMoviePlayerController，播放器正在加载，但文件没有播放。这是代码......

    NSURL *url = [NSURL URLWithString:obj->msg_url]; // obj->url is a html php url not a direct file url.
    moviePlayer =  [[MPMoviePlayerController alloc]
                    initWithContentURL:url];

    moviePlayer.controlStyle = MPMovieControlStyleDefault; 
    moviePlayer.shouldAutoplay = YES;
    [self.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];

所以在这种情况下如何使用MPMoviePlayerController从html url播放。有什么想法吗？

感谢

Answer 1

尝试 [moviePlayer play]; 看起来应该不会总是产生预期效果。

Answer 2

我先下载并立即开始工作。

        NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString  *documentsDirectory = [paths objectAtIndex:0];

        NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"sample.mp4"];
        [urlData writeToFile:filePath atomically:YES];


        NSURL *file_url = [NSURL fileURLWithPath:filePath];
        moviePlayer =  [[MPMoviePlayerController alloc]
                        initWithContentURL:file_url];

        moviePlayer.controlStyle = MPMovieControlStyleDefault;
        moviePlayer.shouldAutoplay = YES;
        [self.view addSubview:moviePlayer.view];
        [moviePlayer setFullscreen:YES animated:YES];
