Hide label when UITableView Cell is tapped
提问by user3746428
I have a label within my cells that I would like to show/hide when tapped. I know that I have to get the index path of the cell that was tapped from within didSelectRowAtIndexPath. But I am unsure of how I then show/hide the label in that particular cell.
我的单元格中有一个标签，我想在点击时显示/隐藏。我知道我必须获取从didSelectRowAtIndexPath. 但我不确定如何在该特定单元格中显示/隐藏标签。
Am I able to show/hide it from within didSelectRowAtIndexPath, or is there a way to deal with it in cellForRowAtIndexPathand then update it?
我可以从内部显示/隐藏它didSelectRowAtIndexPath，还是有办法处理它cellForRowAtIndexPath然后更新它？
I did some research into this but I really couldn't find a whole lot.
我对此进行了一些研究，但我真的找不到很多。
Here is all I have so far:
这是我到目前为止的所有内容：
var selectedRowIndex: NSIndexPath = NSIndexPath(forRow: -1, inSection: 0)
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
selectedRowIndex = indexPath
}

Here is how you get to the cell from the index path:
以下是从索引路径到达单元格的方法：
let cell = tableView.cellForRowAtIndexPath(indexPath) as MyCustomCell
cell.myTextLabel.hidden = true
Also, depending on your needs, you might want to deselect the cell as well.
此外，根据您的需要，您可能还想取消选择单元格。
tableView.deselectRowAtIndexPath(indexPath)
