如何“重新启动"应用ios [英] How to "restart" application ios

问题描述

因此，我有一个应用程序，用户可以通过3个视图控制器，然后将图片提交到Facebook.在他们将其提交到Facebook之后，我希望他们能够选择重新启动该过程，就像他们重新启动了该应用程序一样.

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.

我该怎么办?

谢谢

推荐答案

好吧，因为您对导航模式的了解并不明确，所以我将展示两种过渡及其对立:

OK, because you haven't been clear about your navigation patterns, I'll show the two kinds of transitions and their opposites:

Push-Pop :通过使用

[self.navigationController pushViewController:exampleController animated:YES];

它被

[self popToRootViewControllerAnimated:YES];

模式视图:通过在当前视图上显示一个新的UIViewController来创建.

Modal View: Is created by presenting a new UIViewController over the current one.

[self presentModalViewController:exampleController animated:YES];

它不在导航堆栈上，因此无法在第一个模态视图中显示另一个模态视图.通过调用

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

[self dismissModalViewControllerAnimated:YES];

从模式视图本身内部.
