How to set action in label?

Question

Here is my code:

added gesture in viewDidLoad

let tap = UITapGestureRecognizer(target: self, action: #selector(tapLabel(tap:)))
            toastLabel.addGestureRecognizer(tap)
            toastLabel.isUserInteractionEnabled = true

func showLongToast( message: String) {        
    toastLabel = UILabel(frame: CGRect(x: controller.view.frame.origin.x + 20, y: controller.view.frame.size.height-200, width: controller.view.frame.size.width - 40, height: 125))
    toastLabel.numberOfLines = 0
    toastLabel.textAlignment = .center
    toastLabel.contentMode = .center
    toastLabel.backgroundColor = UIColor.white.withAlphaComponent(0.7)
    toastLabel.textColor = UIColor(red: 74/255, green: 74/255, blue: 74/255, alpha: 1)
    toastLabel.font = UIFont(name: "Montserrat-Medium", size: 15.0)
    let trimmedString = message.trimmingCharacters(in: .whitespacesAndNewlines)
    let string = NSMutableAttributedString(string: trimmedString)
    string.setColorForText("Enter Manually", with: #colorLiteral(red: 1, green: 0.4196078431, blue: 0.1812392979, alpha: 1))
    toastLabel.attributedText = string
    toastLabel.layer.cornerRadius = 25
    toastLabel.clipsToBounds = true
    controller.view.addSubview(toastLabel)
    controller.view.bringSubviewToFront(toastLabel)
  }

I have call the function from viewController :

showLongToast(message: "Please Hold the lens or choose you can Enter Manually.", controller: self)

But toast message could not set action anymore? Have any idea please post in comment. Thanks.

You are adding the tap gesture recognizer to toastLabel in viewDidLoad(), but then you are creating a new UILabel inside showLongToast()

Change:

toastLabel = UILabel(frame: CGRect(x: controller.view.frame.origin.x + 20, y: controller.view.frame.size.height-200, width: controller.view.frame.size.width - 40, height: 125))

in showLongToast() to:

toastLabel.frame = CGRect(x: controller.view.frame.origin.x + 20, y: controller.view.frame.size.height-200, width: controller.view.frame.size.width - 40, height: 125)
