在tableFooterView中的自定义单元格上设置editingStyle [英] Setting editingStyle on custom cell in tableFooterView

问题描述

以下代码(位于我的-viewWillAppear中)成功地将一个单元实现为tableFooterView:

The following code (located in my -viewWillAppear) successfully implements a cell as a tableFooterView:

CGRect cellRect = [self.tableView rectForRowAtIndexPath:0];
    UITableViewCell *footerCell = [[UITableViewCell alloc] initWithFrame:cellRect];
    //footerCell.editingStyle = UITableViewCellEditingStyleInsert;
    footerCell.textLabel.text = @"Add New Class";
    self.tableView.tableFooterView = footerCell;

但是，注释掉的行返回此错误:无法设置对象-只读属性或未找到setter

However, the line that is commented out returns this error: object cannot be set - either readonly property or no setter found

如何设置要插入的此单元格的editingStyle?

How can I set the editingStyle of this cell to insert?

推荐答案

通常，UITableViewCell实例仅用于UITableView行，而不能用于页脚本身.但是，由于它是UIView的子类，所以我想它会起作用.

Normally UITableViewCell instances are meant to only go into UITableView "rows" and not into the footer itself. However since it is subclass of UIView I guess it will work.

您遇到的问题是它是一个只读属性.您尝试设置的信息通常由UITableView通过委托发现.因此，您正在尝试将方钉插入圆孔中.

The issue you are having is that it is a readonly property. The information you are trying to set is normally discovered by the UITableView through delegates. Therefore you are trying to put a square peg into a round hole.

我会创建一个自定义的UIView放在页脚中，而不是尝试在其中放置UITableViewCell.

I would create a custom UIView to put into your footer instead of trying to put a UITableViewCell in there.
