(void)popup
{
    UIView *AView1=[[UIView alloc] initWithFrame:CGRectMake(self.view.frame.size.width/2,self.view.frame.size.height/2, 0, 0)];
    [AView1 setBackgroundColor:[UIColor redColor]];
    [UIView animateWithDuration:2.5 animations:^{AView1.frame = CGRectMake(35, 10, self.view.frame.size.width-70, self.view.frame.size.height-100);}];
}

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];
}
