一次解除多个模态视图控制器？ [英] Dismissing multiple modal view controllers at once?

问题描述

所以有一个带有三个视图控制器的堆栈，其中A是root，B是第一个模态视图控制器，C是第三个模态vc。我想立刻从C到A。我试过此解决方案解雇。它工作但不是以正确的方式。也就是说，当最后一个视图控制器被解除时，它将在显示第一个视图控制器之前完全显示第二个视图控制器。我正在寻找的是一种从第三个vc到第一个vc的方法在一个不错的动画中没有注意到第二个视图。任何有关这方面的帮助都非常适合。

So have a stack with three view controllers where A is root, B is first modal view controller and C is third modal vc. I would like to go from C to A at once. I have tried this solution to dismiss.It does work but not in a correct way. That is when the last view controller is dismissed it will breifly show the second view controller before the first is shown. What I'm looking for is a way to get from the third vc to the first in one nice animation without noticing the second view. Any help on this is greatly appriciated.

推荐答案

请确保您只是在调用 dismissModalViewControllerAnimated：一次。

Be sure that you're only calling dismissModalViewControllerAnimated: once.

我发现要求关闭每个堆叠的模态视图控制器将导致它们都有动画。

I have found that asking to dismiss each stacked modal view controller will cause both of them to animate.

您有： A =模态> B =模态> C

你应该只调用 [myViewControllerA dismissModalViewControllerAnimated：YES]

如果您使用 [myViewControllerB dismissModalViewControllerAnimated：YES] ，它将关闭C，而不是B.在正常（未堆叠）使用中，它会解雇B（由于响应者链将消息冒泡到A）。在您描述的堆叠方案中，B是父视图控制器，这优先于作为模态视图控制器。

If you use [myViewControllerB dismissModalViewControllerAnimated:YES], it will dismiss C, and not B. In normal (unstacked) use, it would dismiss B (due to the responder chain bubbling the message up to A). In the stacked scenario that you describe B is a parent view controller and this takes precedence over being a modal view controller.
