如何检测iPhone UITableView的编辑模式 [英] How to detect edit mode on iPhone UITableView

问题描述

对于我的iPhone应用程序，我有一个可编辑（删除）表视图。我想要能够检测到用户已经点击了编辑按钮。查看此图片： http://grab.by/It0

For my iPhone app, I have an editable (for delete) table view. I'd like to be able to detect that the user has clicked the "Edit" button. See this image: http://grab.by/It0

从文档，它看起来像是如果我实现：

From the docs, it looked like if I implemented :

- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath

然后我可以检测它（虽然从方法的名称，我不会这样认为）。这证明不工作。

then I could detect it (although from the name of the method, I wouldn't think that). This proved not to work.

有关检测此问题的任何想法吗？我想要的原因是我想在删除模式时在左上角连接一个全部删除按钮。

Any ideas on detecting this? The reason I want to is I want to hook up a "Delete all" button in the upper left hand corner when in delete mode.

感谢

推荐答案

它可能不能正常工作，因为 willBeginEditingRowAtIndexPath：

It is probably not working as you expect because willBeginEditingRowAtIndexPath: is called before the editing starts.

如果您想在另一种方法中检查您需要编辑属性：

If you want to check while in another method you need the editing property:

@property(nonatomic, getter=isEditing) BOOL editing

如果要在按下编辑按钮时执行某些操作，您需要实现setEditing方法：

If you want to do something when the 'Edit' button is pressed you need to implement the setEditing method:

 - (void)setEditing:(BOOL)editing animated:(BOOL)animated

这将在 UIViewController 中找到。 （嗯，这是最可能的地方;有其他人。）

Which you'll find in UIViewController. (Well, that's the most likely place; there are others.)
