如何自定义Modal View Controller呈现动画? [英] How to custom Modal View Controller presenting animation?

问题描述

我想添加一个CAAnimation(或其他东西)，而不是设置uiviewcontroller的modalTransitionStyle.这段代码可以在navigationController中执行自定义动画

Instead of setting uiviewcontroller's modalTransitionStyle, I want to add an CAAnimation(or some other thing). This code can perform an custom animation in navigationController

CATransition* transition = [CATransition animation];
          transition.duration = 0.4;
          transition.type = kCATransitionFade;
          transition.subtype = kCATransitionFromBottom;
          [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
          [self.navigationController pushViewController:adjustViewController animated:NO];

如何将其实现到Modal View Controller?

推荐答案

您只需要将过渡添加到窗口的层，并提供您的控制器即可，而不是推送它:

You just need to add the transition to the window's layer, and present your controller rather than pushing it:

     CATransition* transition = [CATransition animation];
     transition.duration = 1;
     transition.type = kCATransitionFade;
     transition.subtype = kCATransitionFromBottom;
     [self.view.window.layer addAnimation:transition forKey:kCATransition];
     [self presentViewController:adjustViewController animated:NO completion:nil];
