UITapGestureRecognizerにパラメーターを送りたい

In this post, I send String parameter to Gesture, but actually you can send all types of parameter.

#Purpose
Personal Note

#Development Environment

• OS X El Captain 10.11.2
• Xcode Version 8.0

#Language
Swift 3.0

1.You have to create class

class MyTapGestureRecognizer: UITapGestureRecognizer {
    var targetString: String?
}

2.Call that class

let gesture = MyTapGestureRecognizer(target: self, action: #selector(self.tapText(tap:)))
gesture.targetString = "Hello Qiita"

func tapText(sender: MyTapGestureRecognizer) {
     print(sender.targetString)
}

Source Code

ViewController.swift

import UIKit

class MyTapGestureRecognizer: UITapGestureRecognizer {
    var targetString: String?
}

class ViewController: UIViewController {
   
    @IBOutlet weak var label: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        let gesture = MyTapGestureRecognizer(target: self, action: #selector(self.tapText(sender:)))
        gesture.targetString = "Hello Qiita"
        label.addGestureRecognizer(gesture)

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

/* Function */
extension ViewController{
    func tapText(sender: MyTapGestureRecognizer) {
        print(sender.targetString!)
    }
}
