use this code inside button action ,in this code viewcontroller is removed, and the "home" viewcontroller is added, with a pageflip like transition

[UIView beginAnimations:@"Flip" context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.base.view cache:YES];

[user.view removeFromSuperview];
[base.view addSubview:home.view];

[UIView commitAnimations];

You can use UIAnimation block, initially set the UIImageView frame to (0,480,320,480). So that it will be out of screen i.e it won't be visible then on button click change the Y coordinate to zero using animation block.

[UIView animateWithDuration:0.5
                      delay:1.0
                    options: UIViewAnimationCurveEaseOut
                 animations:^{
                     self.yourImageView.frame = CGRectMake(0,0,320,480);
                 } 
                 completion:^(BOOL finished){
                     NSLog(@"Done!");
                 }];

Here's a suggestion. Instead of using a UIImageView, use another UIViewController. From your main UIViewController, create a Modal Segue to another UIViewController.

In the attributes inspector of your segue - set the animation to Partial Curl.

In that UIViewController, add your UIImageView with the GIF file - and a back button to dismiss the modal view controller.
