Swift version: 5.6
The iOS UITapGestureRecognizer
class has a built-in way to detect a double tap on any view. All you need to do is create the recognizer, set its numberOfTapsRequired
property to 2, then add it to the view you want to monitor.
Here's an example:
override func viewDidLoad() {
super.viewDidLoad()
let tap = UITapGestureRecognizer(target: self, action: #selector(doubleTapped))
tap.numberOfTapsRequired = 2
view.addGestureRecognizer(tap)
}
@objc func doubleTapped() {
// do something here
}
