This is a similar post about the same problem. @Jason Harwig suggests that you try:

Try using self.view.superview in the animation transition view of the showMoreInfo:

EDIT: Looking at another post, it seems as though adding the subview BEFORE commiting the animations is the problem. Why don't you try that?

Hope that Helps!

dont use

[frontImageView removeFromSuperview];

in this function. What happens is before the animations happen, your view gets removed from superview. Hence, no animation. Instead use this.

[UIView setAnimationDidStopSelector:@selector(removeImageView)];

and make another method,

-(void) removeImageView
{
        if([yourImageView superview])
            [yourImageView removeFromSuperview];
}

Set containerView's frame properly.You have set it to frontImageView.bounds that is not right.
