Answer 1

if (movieExists) 
{ 
    NSURL *url = [NSURL fileURLWithPath:moviePath]; 
    player = [[MPMoviePlayerViewController alloc]initWithContentURL:url]; 
    player.moviePlayer.fullscreen = YES; 
    player.moviePlayer.scalingMode = MPMovieScalingModeAspectFill; 
} 

Answer 2

 self.moviePlayerController = [[MPMoviePlayerController alloc] init]; 

     [self.moviePlayerController.view setFrame:CGRectMake(0, 70,self.view.frame.size.width, self.view.frame.size.height)]; 

     [self.moviePlayerController setShouldAutoplay:NO]; 

     [self.moviePlayerController setContentURL:self.videoURL]; 

     [self.moviePlayerController setFullscreen:YES animated:YES]; 

     self.moviePlayerController.controlStyle=MPMovieControlStyleFullscreen; 

     [self.moviePlayerController play]; 

     [self.view addSubview:self.videoController.view];
