当tableView的allowsMultipleSelectionDuringEditing属性为YES时，如何进行滑动到删除工作？

问题描述

在iOS 5中，如果我在UITableView上将 allowsMultipleSelectionDuringEditing 设置为YES，则滑动到删除不再有效。内置的Mail应用程序支持在编辑模式下滑动到删除和多个选择，我也想这样做。我如何实现这一目标？

In iOS 5, if I set allowsMultipleSelectionDuringEditing to YES on a UITableView then swipe-to-delete no longer works. The built-in Mail app supports both swipe-to-delete and multiple selections in edit mode, and I'd like to do likewise. How do I achieve this?

推荐答案

诀窍是设置 allowsMultipleSelectionDuringEditing 进入编辑模式时为YES，退出编辑模式时将其设置为NO。这样，在编辑模式下滑动到删除和多个选择都可以正常工作。

The trick is to set allowsMultipleSelectionDuringEditing to YES on entering edit mode and set it back to NO on exiting edit mode. This way, both swipe-to-delete and multiple selections in edit mode work.

如果你已经子类 UITableViewController （你可能有），然后你可以这样做：

If you've subclassed UITableViewController (which you probably have), then you can simply do this:

- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
    // Set allowsMultipleSelectionDuringEditing to YES only while
    // editing. This gives us the golden combination of swipe-to-delete
    // while out of edit mode and multiple selections while in it.
    self.tableView.allowsMultipleSelectionDuringEditing = editing;

    [super setEditing:editing animated:animated];
}
