//利用CATransition來作類比

 

//類比Push- (void)pushView:(UIView *)pushView inView:(UIView *)inView{    CATransition *animation = [CATransition animation];    animation.duration = 0.2f;    animation.timingFunction = [CAMediaTimingFunction                                functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    animation.fillMode = kCAFillModeForwards;    animation.type = kCATransitionPush;    animation.subtype = kCATransitionFromRight;    [inView.layer addAnimation:animation forKey:nil];    [inView addSubview:pushView];}//類比pop- (void)navPopView:(UIView *)popView{    CATransition *animation = [CATransition animation];    animation.duration = 0.2f;    animation.timingFunction = [CAMediaTimingFunction                                functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    animation.fillMode = kCAFillModeForwards;    animation.type = kCATransitionPush;    animation.subtype = kCATransitionFromLeft;    [self.view.layer addAnimation:animation forKey:nil];    [popView removeFromSuperview];}
