iOS让push跳转动画像modal跳转动画那样效果

iOS让push跳转动画像modal跳转动画那样效果(从下往上推上来)，iOS核心动画有很多，转场啊，属性动画，基础动画，关键帧动画，弹簧动画，动画组，CoreAnimation类结构，今天讲的是CATransition实现的，废话不多说，上代码。
push

- (void)push
{
TestViewController *vc = [[TestViewController alloc] init];
    vc.view.backgroundColor = [UIColor redColor];
    CATransition* transition = [CATransition animation];
    transition.duration = 0.4f;
    transition.type = kCATransitionMoveIn;
    transition.subtype = kCATransitionFromTop;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
    [self.navigationController pushViewController:vc animated:NO];
}

pop

- (void)pop
{
CATransition* transition = [CATransition animation];
    transition.duration = 0.4f;
    transition.type = kCATransitionReveal;
    transition.subtype = kCATransitionFromBottom;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
    [self.navigationController popViewControllerAnimated:NO];
}
