NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:movieURL];
moviePlayer.useApplicationAudioSession=NO;
[[moviePlayer view] setFrame: CGRectMake(30,70,385,225)];
[self.view addSubview:moviePlayer.view];
[moviePlayer setContentURL:movieURL];
moviePlayer.shouldAutoplay=NO;
}
请帮助。为什么我没有得到输出。
谢谢，萨钦
