For Push:

MainView *nextView=[[MainView alloc] init];[UIView  beginAnimations:nil context:NULL];[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];[UIView setAnimationDuration:0.75];[self.navigationController pushViewController:nextView animated:NO];[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];[UIView commitAnimations];[nextView release];

TwoDView *twoD  =[[TwoDView alloc]init];    CATransition *animation = [CATransition animation];    [animation setDuration:0.4];    [animation setType: kCATransitionPush];    [animation setSubtype: kCATransitionFromLeft];    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];    [self.navigationController pushViewController:twoD animated:NO];    [self.navigationController.view.layer addAnimation:animation forKey:nil];    [twoD release];

For Pop:

方法一：

[UIView  beginAnimations:nil context:NULL];[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];[UIView setAnimationDuration:0.75];[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];[UIView commitAnimations];[UIView beginAnimations:nil context:NULL];[UIView setAnimationDelay:0.375];[self.navigationController popViewControllerAnimated:NO];[UIView commitAnimations];

方法二：

可实现左右滑动动画，可设置滑动方向。

CATransition* transition = [CATransition animation];transition.duration = 0.5;transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade//transition.subtype = kCATransitionFromTop; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom[self.navigationController.view.layer addAnimation:transition forKey:nil];[[self navigationController] popViewControllerAnimated:NO];
