ios - 让推送像现在一样生动

Question

我正在尝试推送一个 viewController，我想更改推送的动画。原来的puch动画是从右/左翻转的，我需要从底部制作，就像present的动画一样。我尝试了以下代码，它可以工作，但是当 viewcontroller 设置动画时背景将是黑色的。我可以用它做什么？

CATransition *animation = [CATransition animation];
animation.duration = 2.0f;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
animation.fillMode = kCAFillModeForwards;
animation.type = kCATransitionPush;
animation.subtype = kCATransitionFromTop;
[[self.navigationController.view layer] addAnimation:animation forKey:@"animation"];
[self.navigationController pushViewController:controller animated:NO];

Answer 1

嘿，你可以使用下面的方法，同时在带有动画 NO 的导航 Controller 中推送 Controller

- (void)animateControllerFromBottomToTop
{
    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];
    [animation setType:kCATransitionPush];
    [animation setSubtype:kCATransitionFromTop];
    [animation setDuration:0.65f];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.navigationController.view layer] addAnimation:animation forKey:@"AnimationFromBottomToTop"];
}
