更改标准视图控制器中的表格视图单元格 [英] Changing a table view cell in a standard view controller'

问题描述

我有一个 TableView，其中有一个需要更改背景颜色的单元格.我尝试寻找更改单元格背景颜色的答案，但问题是我找到的每个答案都与覆盖 tableview 函数有关，该函数不起作用，因为我没有 tableviewcontroller，而是一个嵌入了 UITableView 的普通视图控制器.

如何简单地更改单元格的背景颜色?

解决方案

首先通过故事板给你的表格视图单元一个标识符，如下所示:

然后另外

I have a TableView and in it I have a cell that I need to change the background color of. I've tried searching for an answer to change the background color of the cell but the problem is that every answer I find has to do with an override tableview function, which will not work because I do not have a tableviewcontroller, rather it is a normal view controller with a UITableView embedded.

How can I simply change the background color of the cell?

解决方案

First give your table view cell an Identifier via the storyboard like this:

Then additionally to vadian's answer access your cell in the tableView(_:cellForRowAt:) DataSource method like this and update the color, in the example I put the method in an extension:

extension ViewController: UITableViewDataSource {

  func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    cell.backgroundColor = UIColor.cyan

    return cell
  }

}

Also don't forget to add the tableView(_:numberOfRowsInSection:) method to conform the UITableViewDataSource protocol

Like rMickeyD mentioned in the comments, don't forget to set your table view as dataSource and delegate with Ctrl + Drag from the table view to the view controller like this:
