How to get UIButton name in swift5?

Question

I am currently making a pin-code. I want to incorporate all the functions into one function, in order to integrate the button event function into one So I want to get the name of UIButton, but I don't know how.

@IBOutlet weak var oneButton: UIButton!
@IBOutlet weak var twoButton: UIButton!
...
var pinCodeNum : String! = ""
...

  @IBAction func OneButton(_ sender: UIButton) {
        pincodeLogic(sender)
    }

    func pincodeLogic(_ sender: UIButton) {
         // I want get value is (example : 'oneButton' or 'twoButton' or 'threeButton' more )
    }

As you can see from my code, I'm getting a 'sender' as a parameter I want to know the name of oneButton or twoButton using this parameter. How do I know?

My number button consists of a button and a label.

EDit

  @IBAction func OneButton(_ sender: UIButton) {

        pincodeLogic(sender)
    }

    func pincodeLogic(_ sender: UIButton) {
         if let number = sender.currentTitle {
            print(number)
        }
    }

I can't see the print log.

Hi @Fogmeister What do you mean by adding different functions to each button? — iosbegindevel, Sep 17 '19 at 09:34
create the common method for each button and get directly sender.currentTitle using touchup action. — Anbu.Karthik, Sep 17 '19 at 09:34
@Anbu.Karthik is right, you should use `sender.currentTitle` — Sagar Chauhan, Sep 17 '19 at 09:37
Hi @Anbu.Karthik I can't see the print log when I click one Button, Please look at the modified question. — iosbegindevel, Sep 17 '19 at 09:38
Hi @SagarChauhan I can't see the print log when I click one Button, Please look at the modified question. — iosbegindevel, Sep 17 '19 at 09:38
@iosbegindevel, `My number button consists of a button and a label.` What that means ? — Sagar Chauhan, Sep 17 '19 at 09:47
@iosbegindevel you have 10 buttons. So have ten functions `@IBAction buttonOnePressed() {}` etc... — Fogmeister, Sep 17 '19 at 09:47
Ah ~ @Fogmeister I understand what you mean. I know I have to make ten of them. I just want to use a function as a function in a function. Is it impossible for me to do what I'm trying to do? — iosbegindevel, Sep 17 '19 at 09:50
Even with ten functions you can call out to a single function that does the logic. `addNumberToPin(1)` etc... — Fogmeister, Sep 17 '19 at 09:53
@SagarChauhan The circle is the button and the number is the label. — iosbegindevel, Sep 17 '19 at 10:04
@iosbegindevel, that's why `sender.currentTitle` is not work for you, because button haven't a title. — Sagar Chauhan, Sep 17 '19 at 10:11
@SagarChauhan My button is an image, can I put in a number? I didn't know it, so I had to use the label uncomfortably. — iosbegindevel, Sep 17 '19 at 10:24

You can compare the sender with your button instances.

func pincodeLogic(_ sender: UIButton) {
    switch sender {
    case oneButton:
        print("oneButton pressed")
    case twoButton:
        print("twoButton pressed")
    default:
        print("unknown button pressed")
    }
}

if you want to access the button action to perform some specific task.Just put a tag with your each button and add the same target to all.

@IBAction func btnAction(_ sender: UIButton) {
switch sender.tag {
case 1:
    print("oneButton pressed")
case 2:
    print("twoButton pressed")
default:
    print("unknown button pressed")
 }
}

If you need just to print the button title the do the following.

@IBAction func btnAction(_ sender: UIButton) {
   print(sender.titleLabel?.text! as! String)
}

To access the contents of the label present in the button using the sender, this is an example:

@IBAction func OneButton(_ sender: UIButton) {
   print(sender.titleLabel?.text)
}

so you could do this:

@IBAction func OneButton(_ sender: UIButton) {

        pincodeLogic(sender)
  }

  func pincodeLogic(_ sender: UIButton) {
         if let number = sender.titleLabel?.text {
            print(number)
        }
  }

I hope I've been there for you. Let me know.

it also I can't see the print log when I click one Button, – iosbegindevel Sep 17 '19 at 09:51 — iosbegindevel, Sep 17 '19 at 09:51
