You won't be able to open like a popup a UIViewController.

For that you will have to use a simple UIView

Add the UIview (popup shape like) to your current view.

- (void) initPopUpView {
  popup.alpha = 0;
  popup.frame = CGRectMake (160, 240, 0, 0);
  [self.view addSubview:popup];
}

- (void) animatePopUpShow {
  [UIView beginAnimations:nil context:NULL];
  [UIView setAnimationDuration:0.3];
  [UIView setAnimationDelegate:self];
  [UIView setAnimationWillStartSelector:@selector(initPopUpView)];

  popup.alpha = 1;
  popup.frame = CGRectMake (20, 40, 300, 400);

  [UIView commitAnimations];
}
