UITableViewCell，滑动时显示删除按钮

问题描述

如何在 UITableViewCell 上滑动时显示删除按钮?永远不会引发该事件，也永远不会出现删除按钮.

How do I get the delete button to show when swiping on a UITableViewCell? The event is never raised and the delete button never appears.

推荐答案

在 (-viewDidLoad or in storyboard) 中启动时执行:

self.tableView.allowsMultipleSelectionDuringEditing = NO;

覆盖以支持表格视图的条件编辑.仅当您要为某些项目返回 NO 时才需要实施.默认情况下，所有项目都是可编辑的.

Override to support conditional editing of the table view. This only needs to be implemented if you are going to be returning NO for some items. By default, all items are editable.

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    // Return YES if you want the specified item to be editable.
    return YES;
}

// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        //add code here for when you hit delete
    }
}
