ios - 在表格 View 中点击标签？

Question

我有一个标签，我想使用 addGestureRecognizer 点击。我把它放在 cellForRowAtIndexPath 中，但是当我执行 print(label.text) 时，它会打印来自另一个单元格的标签。但是当我将它放入 didSelectRowAtIndexPath 时，它会打印出该单元格的正确标签。

解决此问题的最佳方法是什么？

代码如下:

var variableToPass: String!

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell : MainCell! = tableView.dequeueReusableCellWithIdentifier("MainCell") as! MainCell

        variableToPass = label1.text

        cell.label1.userInteractionEnabled = true
        let tapLabel = UITapGestureRecognizer(target: self, action: #selector(ViewController.tapLabel(_:)))
        cell.label1.addGestureRecognizer(tapLabel)



        return cell as MainCell
    }

func tapCommentPost(sender:UITapGestureRecognizer) {
    print(variableToPass)
    }

我想你忘记设置 tap.tag = indexPath.row 来识别你为 Find 选择的单元格，例如

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell : MainCell! = tableView.dequeueReusableCellWithIdentifier("MainCell") as! MainCell

        variableToPass = label1.text

        cell.label1.userInteractionEnabled = true
        let tapLabel = UITapGestureRecognizer(target: self, action: #selector(ViewController.tapLabel(_:)))
        cell.label1.tag = indexPath.row
        tapLabel.numberOfTapsRequired = 1
        cell.label1.addGestureRecognizer(tapLabel)



        return cell as MainCell
    }

func tapLabel(sender:UITapGestureRecognizer) {

    let searchlbl:UILabel = (sender.view as! UILabel)
    variableToPass =  searchlbl.text!
    print(variableToPass)
    }
