ios - 如何自定义模态视图 Controller 呈现动画？

Question

我不想设置 uiviewcontroller 的 modalTransitionStyle，而是想添加一个 CAAnimation(或其他东西)。此代码可以在 navigationController 中执行自定义动画

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];

如何将它实现到模态视图 Controller ？

Answer 1

您只需要将过渡添加到窗口层，并呈现您的 Controller 而不是推送它:

     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];
