How to "restart" application ios
提问by Szwedo
So I have an app where a user goes through 3 view controllers and then submits a picture to Facebook. After they submit it to Facebook, I want them to be able to choose to restart the process over again, as if they had re-launched the app.
所以我有一个应用程序，用户通过 3 个视图控制器然后将图片提交到 Facebook。在他们将其提交给 Facebook 后，我希望他们能够选择重新启动该过程，就好像他们重新启动了该应用程序一样。
How could I do this?

OK, because you haven't been clear about your navigation patterns, I'll show the two kinds of transitions and their opposites:
好的，因为你还没有清楚你的导航模式，我将展示两种过渡及其对立：
Push-Pop: Is created by pushing a new UIViewController onto the navigation stack using
Push-Pop：通过使用将新的 UIViewController 推送到导航堆栈上来创建
[self.navigationController pushViewController:exampleController animated:YES];
It is counteracted by
它被抵消
[self popToRootViewControllerAnimated:YES];
Modal View: Is created by presenting a new UIViewController over the current one.
模态视图：通过在当前视图上呈现一个新的 UIViewController 来创建。
[self presentModalViewController:exampleController animated:YES];
It is not on the navigation stack, so the possibility of presenting another modal view within the first modal view is not available. It is counteracted by calling
它不在导航堆栈中，因此无法在第一个模态视图中呈现另一个模态视图。它通过调用来抵消
[self dismissModalViewControllerAnimated:YES];
from within the modal view itself.
从模态视图本身。
