推荐答案

使用以下代码

-(void)movieReceived{
{
       NSString *strVideoUrl = @"abc.com/xyz" // your VideoUrl in String
       strVideoUrl = [strVideoUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
       NSURL *url = [NSURL URLWithString:strVideoUrl];
       moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];

       [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
       [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDonePressed:) name:MPMoviePlayerDidExitFullscreenNotification object:moviePlayer];

       moviePlayer.controlStyle=MPMovieControlStyleDefault;
       //moviePlayer.shouldAutoplay=NO;
       [moviePlayer play];
       [self.view addSubview:moviePlayer.view];
       [moviePlayer setFullscreen:YES animated:YES];
}

- (void) moviePlayBackDonePressed:(NSNotification*)notification
{
       [moviePlayer stop];
       [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerDidExitFullscreenNotification object:moviePlayer];


       if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)])
       {
              [moviePlayer.view removeFromSuperview];
       }
       moviePlayer=nil;
}

- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
      [moviePlayer stop];
      [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];

     if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)])
     {
          [moviePlayer.view removeFromSuperview];
