swift - AddGestureRecognizer 不适用于 tableViewCell 中的 UILabel

Question

我正在尝试在 tableView 单元格内的 UILabel 中添加点击事件，如下所示。

let tap = UITapGestureRecognizer(target: self, action: #selector(downloadFile(_:)))
let msgLabel = cell.viewWithTag(1000) as! UILabel
msgLabel.isUserInteractionEnabled = true
msgLabel.addGestureRecognizer(tap)

这是我的downloadFile函数。

@objc func downloadFile(_ sender:Any){
    print("tapped")
}

谁能帮我解决这个问题

Answer 1

tap.delegate =self;
tap.numberOfTapsRequired = 1;

将上述代码添加到 UITapGestureRecognizer 对象中。这样就可以了:

let tap = UITapGestureRecognizer(target: self, action: #selector(downloadFile(_:)))
tap.delegate =self;
tap.numberOfTapsRequired = 1;
let msgLabel = cell.viewWithTag(1000) as! UILabel
msgLabel.isUserInteractionEnabled = true
msgLabel.addGestureRecognizer(tap)
