Use the CATransition class in the Core Animation Framework (Quartz Core Framework).

This is what push-like animation looks like.

 CATransaction begin;
    CATransaction setValue: (id)kCFBooleanTrue
                     forKey —kCATransactionDisableActions ;

    CATransition* transition= CATransition animation;
    transition.delegate=self;
    transition.duration=.4f;
    transition.timingFunction= [CAMediaTimingFunctionFunctionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type =kCATtransitionPush;
    transition.subtype=(isRight)?kCATtransitionFromLeft:kCATtransitionFromRight;
    targetView.layer addAnimation:transition
                                     forKey:nil];

    CATransaction commit ;
