问题描述
有没有办法让一个按钮回到特定的视图控制器?例如，假设我有 ViewController A 和 B.两者都模态地转至 ViewController C.现在我了解如何转回之前的视图控制器之一(正如这里所解释的)但我如何返回到呈现 VC C 的特定视图控制器?
Is there a way to have one button unwind back to a specific view controller? For example suppose I have ViewController A and B. Both modally segue to ViewController C. Now I understand how to segue unwind back to one of the previous view controllers (As was explained here) but how do I go back to the specific view controller that presented VC C?
总而言之，我想弄清楚的是......如果 A segued 到 C 那么我想在选择按钮时回到 A .如果 B 转到 C，那么我想在选择按钮时回到 B.
So to sum it up, what I'm trying to figure out is...If A segued to C then I want to unwind back to A when the button is selected. If B segued to C then I want to unwind back to B when the button is selected.
推荐答案
您应该使用标准方式从模态转场返回.把它放在你的后退"按钮...
You should use the standard way to return from a modal segue. Put this in your 'back' button...
[[self presentingViewController] dismissViewControllerAnimated:YES];
这不使用 storyboard 或 segue 来返回，只使用代码.
This doesn't use the storyboard or a segue for the return, just code.
