如何推送两个视图控制器，但仅为第二个控制器设置动画转换？ [英] How to push two view controllers but animate transition only for the second one?

问题描述

我在storyboad中有三个控制器（FirstVC，SecondVC，ThirdVC），导航是顺序的：用户可以从FirstVC导航到SecondVC，然后导航到ThirdVC。现在，我需要制作一些按钮，它将从FirstVC打开ThirdVC，但也会将SecondVC放在导航堆栈上，所以当用户从ThirdVC按回来时，他将返回到SecondVC。因此，我不需要从FirstVC到SecondVC的动画，只需要在导航控制器堆栈上推送SecondVC，然后仅动画转换到ThirdVC。

I have three controllers (FirstVC, SecondVC, ThirdVC) inside storyboad, and navigation is sequential: a user can navigate from FirstVC to SecondVC, and then to ThirdVC. Now, I need to make some button that will open ThirdVC from FirstVC but will also put SecondVC on navigation stack, so when a user will press back from ThirdVC he will be returned to SecondVC. So, I don’t need animation from FirstVC to SecondVC, just need to push SecondVC on navigation controller stack and then animate only transition to ThirdVC.

我无法找到如何禁用performSegueWithIdentifier的动画，所以我想我应该手动从storyboard中实例化SecondVC，将它放在导航堆栈上，然后执行performSegueWithIdentifier for ThirdVC。任何想法如何做？

I was unable to find how disable animation for performSegueWithIdentifier, so I’m thinking I should instantiate SecondVC from storyboard manually, put it on navigation stack, and then perform performSegueWithIdentifier for ThirdVC. Any ideas how to do that?

推荐答案

如果你在第一个VC中，你正在寻找解决方案：

The solution you're looking for if you're in the firstVC:

NSMutableArray *controllers = [self.navigationController.viewControllers mutableCopy];
[controllers addObject:secondVc];
[controllers addObject:thirdVC];
[self.navigationController setViewControllers:controllers animated:YES];

这将在第三个VC中设置动画，而不会在此过程中显示第二个VC。当用户按下后退按钮时，它们将返回到secondVc

This will animate in the thirdVC without the secondVc becoming visible in the process. When the user press the back button, they will return to the secondVc
