如何在界面生成器中添加条形按钮项? [英] How to add a bar button item in interface builder?

问题描述

我真的是iPhone开发的新手，我需要帮助设置我的观点.

I am really new to iPhone development and I need help setting up my views.

我有一个名为FirstViewController.xib的视图和该视图的控制器类.

I have a view that is named FirstViewController.xib and a controller class for this view.

在我的MainWindox.xib中，我设置了具有moveToNextView功能的根控制器，该功能连接到选项栏按钮项.

In my MainWindox.xib I have setup a root controller with a moveToNextView function that is connected to the options bar button item.

因此，当我单击此项目时，当前视图将切换到第一个视图，并且可以切换回原来的视图.到目前为止，一切正常.

So when I click on this item the current view switches to the first view and I am able to swticht back. That works fine so far.

MainWindow.xib中位于屏幕顶部的导航栏也显示在第一个视图中.但是当我打开FirstViewController.xib时，没有定义任何导航栏(但是在build&运行时会显示出来).

The navigation bar at the top of the screen from the MainWindow.xib is displayed in the first view, too. But when I open FirstViewController.xib there isn't any navigation bar defined (but on build&run it is displayed).

这对我来说是个问题，因为我想在第一个视图中添加一个保存栏项.我该怎么解决?

This is a problem for me because I want to add a save bar item to the first view. How do I solve that?

推荐答案

您必须通过代码来完成.添加到您的FirstViewController类viewDidLoad方法:

You have to do it from code. Add to your FirstViewController class viewDidLoad method:

  UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Save" style:UIBarButtonItemStyleDone target:self action:@selector(doSave:)];
  self.navigationItem.rightBarButtonItem = anotherButton;
  [anotherButton release];
