问题描述

iOS 5.0，xCode 4.2

iOS 5.0, xCode 4.2

我正在做一个多步调查问卷。

I am doing a multistep questionnaire.

大约有10个问题在每个分支上，还有子分支。
但逻辑是相当线性的。大多数是/否答案，但有一些多项选择。
问卷将在结论页面上显示。

There are about 10 questions on each branch, and there are sub branches. But the logic is fairly linear. Mostly Yes/no answers, but some multi choice options. The questionnaire will come to a conclusion page.

在这个结论页面上，我想有一个按钮，上面写着HOME
用户到特定的起始页面，以便他们可以重新开始。

On this conclusion page, I would like to have a button that says HOME which takes the user to a specific start page so they can start again.

问题是我想要清除导航控制器堆栈，以便后退按钮不会循环过去选择。

The problem is that I want the navigation controller stack to be cleared so the back buttons will not loop through the past selections.

换句话说，我想清除导航堆栈上的所有视图控制器。有一种简单的方法吗？

Put another way, I want to clear out all of the view controllers on the navigation stack. Is there a simple way to do this?

推荐答案

popToRootViewControllerAnimated： on UINavigationController将清除堆栈并返回根控制器。

popToRootViewControllerAnimated: on UINavigationController will clear out the stack and return you to the root controller.
