Detect long press on tableview

Question

I know how to simply detect a long press, but it detect after release. How can I detect the long press without releasing the finger?

This is the code I am using for long press now:

override func viewDidLoad() {
    super.viewDidLoad()
    setupLongPressGesture()
}

func setupLongPressGesture() {
    let longPressGesture:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: #selector(self.handleLongPress))
    longPressGesture.minimumPressDuration = 1.0 // 1 second press
    longPressGesture.delegate = self
    self.tableView.addGestureRecognizer(longPressGesture)
}

@objc func handleLongPress(_ gestureRecognizer: UILongPressGestureRecognizer){
    if gestureRecognizer.state == .ended {
        let touchPoint = gestureRecognizer.location(in: self.tableView)
        if let indexPath = tableView.indexPathForRow(at: touchPoint) {

        }
    }
}

Answer 1

Change .ended to .began.

From the documentation for UILongPressGestureRecognizer:

Long-press gestures are continuous. The gesture begins (UIGestureRecognizer.State.began) when the number of allowable fingers (numberOfTouchesRequired) have been pressed for the specified period (minimumPressDuration) and the touches do not move beyond the allowable range of movement (allowableMovement). The gesture recognizer transitions to the Change state whenever a finger moves, and it ends (UIGestureRecognizer.State.ended) when any of the fingers are lifted.
