播放视频

播放视频方法一：

MPMoviePlayerController *moviePlayer;
moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:[coursewareRow objectForKey:@"网址"]]];
//    moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"movie" ofType:@"mp4”]]];//本地文件
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES];
[moviePlayer prepareToPlay];
[moviePlayer play];

 
播放视频方法二：该方法有时候会莫名其妙加载其他视图控制器里边的图片

MPMoviePlayerViewController *moviePlayerViewController;
    moviePlayerViewController=[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:[coursewareRow objectForKey:@"网址"]]];
    [self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
