将子视图添加到选定的tableview单元格

I have this code as following. I am trying to add a subview with background color red to my selected tableView cell. But I am facing two bugs:

我有这样的代码如下。我正在尝试将背景颜色为红色的子视图添加到我选择的tableView单元格中。但我面临两个错误:

1: The height of the tableView Cell is 44, but when I set my subView's height to be 44, it seems to be half of the cell height. I can only make the two views equal when the subView frame height is set to be 88.

1:tableView Cell的高度为44,但是当我将subView的高度设置为44时,它似乎是单元格高度的一半。当subView框架高度设置为88时,我只能使两个视图相等。

2: The subView only shows up when I tab it twice. If I tab it for only once, The sub View doesn't show up.

2:当我选中它两次时,子视图才会显示。如果我只选择一次,则子视图不会显示。

BTW: I have two tableViews in one viewController, so please look at the tableView inside of "else".

顺便说一句:我在一个viewController中有两个tableView,所以请查看“else”中的tableView。

The problem in you code is that you try to add selectedBar view directly to selectedCell and this isn't valid you must add it to contentView of selectedCell

您的代码中的问题是您尝试将selectedBar视图直接添加到selectedCell,这是无效的您必须将其添加到selectedCell的contentView

like this

  selectedCell.contentView.addSubview(selectedBar)

Also selectedBar is shown when you tap twice because you must add this to the end of didSelectRowAt

当您点击两次时也会显示selectedBar,因为您必须将其添加到didSelectRowAt的末尾

  tableView.deselectRow(at: indexPath, animated: false)

// Edit -> add tag of 555 when you create the view

//编辑 - >创建视图时添加555的标记

add this code in cellForRowAt

在cellForRowAt中添加此代码

if(index == indexpath.row)
{
      // add the view here 

}
else
{
   for i in 0..<selectedCell.contentView.subviews.count
   {
     let cv = selectedCell.contentView.subviews[i]

     if cv.tag == 555
     {
        cv.removeFromSuperview()
     }

   }

}

Note: when you select didSelectCellAt update only the index to indexpath.row

注意:当您选择didSelectCellAt时,仅更新indexpath.row的索引

and reload the table

并重新加载表
