问题描述

我正在使用带有导航控制器的应用程序。我知道在视图最初加载时如何设置标题。我推了一个新的视图控制器并设置了它的标题。现在的问题是，当我按下后退按钮时，原始视图控制器的标题不再存在。我试图做...

I am working on an app with a navigation controller. I know how to set the title when the view loads initially. I push a new view controller and set it's title. Now the problem is when I press the back button, the title for the original view controller is not there anymore. I tried to do...

- (void)viewWillAppear:(BOOL)animated {
    self.navigationController.title = @"Some Title";
}

虽然这没有设置标题。有人知道我能做什么吗？

This did not set the title though. Does anyone know what I can do?

推荐答案

UINavigationController从当前的UIViewController获取标题的值。

The UINavigationController gets the value for the title from the current UIViewController.

要设置视图控制器的标题，只需执行以下操作：

To set a the title for a view Controller, simply do the following:

- (void)viewDidLoad {

   [super viewDidLoad];
   self.title = @"Some Title";
}

对于每个View Controller，包括根控制器。

For each of your View Controllers, including the root one.
