UITableview 编辑/完成按钮

UITableview edit/done button(UITableview 编辑/完成按钮)

问题描述

我在顶部有一个表格视图和导航栏.

I have a tableview and navigation bar on the top.

我的导航栏左侧有一个编辑按钮，其中包含以下代码行.

I have a Edit button on the left of my navigation bar with the following line of code.

self.navigationItem.leftBarButtonItem = self.editButtonItem;

当我点击编辑按钮时，它变为完成按钮.到目前为止一切都很好.

When i click on the edit button, it changes to done button. All is fine so far.

如果我想在点击完成按钮时做一个小操作，我应该在哪里添加代码?

Where do i add code, if i want to do a small operation when the Done button is clicked.?

推荐答案

一旦你用 self.editButtonItem.action = @selector(editClicked:);

你应该做的是在你自己的控制器类中重写 UIViewController 的 setEditing 方法:

What you should do is override UIViewController's setEditing method in your own controller class:

- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];

    if(editing == YES) 
    {
        // Your code for entering edit mode goes here
    } else {
        // Your code for exiting edit mode goes here
    }
}

您还需要在情节提要中将 UIBarButtonItem 设置为编辑"，或者如果您更喜欢在代码中执行此操作，请使用以下代码:

You also need to set your UIBarButtonItem to "Edit" in storyboard or if you prefer doing it in code use the following:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

editButtonItem 是系统已经为您设置的辅助属性.

editButtonItem is a helper property already set by the system for your comfort.
