Question

好的，所以我的项目（确实有Cocos2d）有3个UITableViews。到目前为止，我只关心第一个，这就是为什么我只粘贴第一个代码的原因。问题是，每当我使用应用程序时，表格视图都会显示，并显示所有内容。编辑/完成按钮也会显示在右下角。但是，每当我尝试按下编辑按钮时，按钮切换到完成，但单元格附近没有删除图标，也无法删除单元格。我尝试了很多解决方案，但似乎都没有。提前谢谢。

Answer 1

将tableView的属性“editing”设置为“YES”。像：

questionTableView.editing = YES;

删除此行：

questionTableView.allowsMultipleSelectionDuringEditing = YES;

选择时

或将allowsMultipleSelectionDuringEditing设置为“NO”。

Answer 2

在edit按钮操作中，您需要将setEditing设为YES。

[tableView setEditing:YES animated:YES];

Answer 3

你在- (void)setEditing之前错过了几个结束大括号，而不应该是你的init方法return self;

Cocos2d UITableView编辑按钮显示但不显示删除图标
