Detect button being tapped - iOS

Question

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

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

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
    }


}
