Change view with navigation controller

Question

我有一个viewBased项目，有两个视图“ A”和“ B”，并在视图A上放置了一个按钮，并希望在用户按下按钮时显示视图B。我如何使用导航控件显示视图B（即通过按钮显示）使用下面的代码，但在此代码之前我不知道该怎么办（表示如何设置UINavigation控件，...）

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

Answer 1

Just pop view B from the nav controller.

So when you press the button in view B just do this:

[self.navigationController popViewControllerAnimated:YES]
