快速点击手势不触发

Question

I want to trigger the tap gesture whenever I tap on an item in my UIPickeView.

I'm using the following code for LongPress Gesture which works fine. However if I switch to UITapGestureRecognizer, nothing is triggered.

FULL CODE UPDATE!

 @IBOutlet weak var showClaims: UIPickerView!

    override func viewDidLoad() {

        super.viewDidLoad()
showClaims.isUserInteractionEnabled = true
        let tapped = UITapGestureRecognizer(target: self, action: #selector(ClaimVC.SelectClaimInfo))

        showClaims.addGestureRecognizer(tapped)
}


func SelectClaimInfo() {
        GetClaimInfo()
}

I believe @dfd is correct in the comments.

Example:

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

private func setupTapGesture()
{
    let tapGesture = UITapGestureRecognizer(target: self,
                                            action: #selector(myVC.doStuff(_:)))
    view.addGestureRecognizer(tapGesture)
}

func doStuff(gesture: UITapGestureRecognizer) {}

You did miss the:

view.addGestureRecognizer(tapGesture)

Update: check touchesBegan from this SO: touchesBegan Swift 3.0 With it you can check if your UIPicker is reaciving touchers properly.

For who Tap Gesture not work for them until make everything as that:

let tap = UITapGestureRecognizer(target: self, action:#selector(self.handleTap(_:)))
myView.addGestureRecognizer(tap)

try to conforms UIGestureRecognizerDelegate and then mKE tap.delegate = self and you must implement this UIGestureRecognizerDelegate method make

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }
