Detect button being tapped - iOS

I'm working with objective-c and I want to detect when the user is tapping a button (not when he tapped it, but the actual moment when is being taped until he stops). Is there any method? I'm not finding it if there's any. Thanks

Here (UIControlEvents) are all events of control/actions (with their brief description)

  • UIControlEventTouchCancel: A system event canceling the current touches for the control.
  • UIControlEventTouchDown: A touch-down event in the control; when button is tapped/pressed.
  • UIControlEventTouchDownRepeat: A repeated touch-down event in the control; for this event the value of the UITouch tapCount method is greater than one.
  • UIControlEventTouchDragEnter: An event where a finger is dragged into the bounds of the control.
  • UIControlEventTouchDragExit: An event where a finger is dragged from within a control to outside its bounds.
  • UIControlEventTouchDragInside: An event where a finger is dragged inside the bounds of the control.
  • UIControlEventTouchDragOutside: An event where a finger is dragged just outside the bounds of the control.
  • UIControlEventTouchUpInside: A touch-up event in the control where the finger is inside the bounds of the control.
  • UIControlEventTouchUpOutside: A touch-up event in the control where the finger is outside the bounds of the control.

Use Touch Down to get button tapping event.

Using touchDown event you can make an action while your button is pressed

enter image description here

Example

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var label: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

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

    @IBAction func testing(_ sender: Any) {
        label.textColor = UIColor.red
    }

    @IBAction func testingCancel(_ sender: Any) {
        label.textColor = UIColor.black
    }

    @IBAction func testingUpInside(_ sender: Any) {
        label.textColor = UIColor.black
    }


}
