Master/Detail 应用程序中的 NavigationItem [英] NavigationItem in Master/Detail application

问题描述

我使用 XCode 的 Master/Detail 模板编写了一个 Master/Detail 应用程序.启动应用程序后，主视图的导航按钮的标题只是主".现在我想重命名那个按钮，但不幸的是我不知道如何访问这个按钮.在 appdelegate.m 中有以下代码来初始化视图:

I wrote a Master/Detail Application by using the Master/Detail template of XCode. After starting the app, the title of the navigation button for the master view is just "Master". Now I waant tio rename that button, but unfortunately I don't know how to access this button. In appdelegate.m there is the following code to initialize the views:

MasterViewController *masterViewController = [[MasterViewController alloc] init];
UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];

DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController]

我尝试了这些方法都没有成功:

I tried these ways without success:

masterViewController.navigationItem.title = @"newTitle";

或

masterNavigationController.navigationItem.title = @"newTitle";

因为我不确定，如果按钮的名称只是 idt 后面的视图的标题，我也尝试过:

As I wasn't sure, if the name of the button is just the title of the view behind idt, I also tried that:

masterViewController.title = @"newTitle";

masterViewController.title = @"newTitle";

没有任何效果.但是由于按钮的标题是Master"，我绝对没有设置它，我相信一定有某种方法可以设置它.有人知道怎么做吗?

Nothing worked. But as the title of the button is "Master" and I definitely didn't set it, I believe there must be some way to set it. Does anyone know how to do it?

只是为了显示按钮:

推荐答案

如果您想使用 Master/Detail Template 创建 Master/Detail 应用程序，请转到您的 "MasterViewController.m" 文件并根据需要更改字符串Master".见下图，它在你的 MasterViewController.m 中是这样的.

If you would have created Master/Detail application using Master/Detail Template, then go to your "MasterViewController.m" file and change the string "Master" as you wanted. See the below image it would be like this in your MasterViewController.m.

更新:并更改 DetailViewController.m 中的 barButtonItem 名称，如下所示.这将解决问题.

UPDATE: and also change the barButtonItem name in the DetailViewController.m as like below. This will do the trick.
