Is there away to use a UILongPressGestureRecognizer over a UITextField without triggering field edit while still being able to edit the textfield on a regular tap?
I have tried adding a long press gesture recognizer to the UITextField but the long press seems to only work a fraction of the time.
init(frame: CGRect, userCompany: WLUserCompany) {
super.init(frame: frame)
var textField: UITextField?
var longPress = UILongPressGestureRecognizer(target: self, action: #selector(self.longPress(gesture:)))
textField?.addGestureRecognizer(longPress)
self.addSubview(textField!)
}
@objc func longPress(gesture: UILongPressGestureRecognizer) {
if gesture.state == UIGestureRecognizerState.began {
print("Long Press")
}
}
Create subclass of UIGestureRecognizer
import UIKit.UIGestureRecognizerSubclass
class TouchGestureRecognizer: UIGestureRecognizer {
var isLongPress: Bool = false
fileprivate var startDateInterval: TimeInterval = 0
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent) {
super.touchesBegan(touches, with: event)
state = .began
self.startDateInterval = Date().timeIntervalSince1970
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent) {
super.touchesEnded(touches, with: event)
state = .ended
self.isLongPress = (Date().timeIntervalSince1970 - self.startDateInterval) > 1.0
}
}
Add gesture recognizer
to your textField
let gesture = TouchGestureRecognizer(target: self, action: #selector(ViewController.textFiledPressed(gesture:)))
self.textField?.addGestureRecognizer(gesture)
And now you can check in textFiledPressed(gesture:)
function if it's long press or not
func textFiledPressed(gesture: TouchGestureRecognizer) {
switch gesture.state {
case .ended:
if gesture.isLongPress {
//Do whatever you need
} else {
self.textField?.becomeFirstResponder()
}
default: break
}
}
After looking at similar SO here and here , and experimenting myself, I don't think this is possible -- at least the way you describe your intent.
I was able to add a background view with gesture control, but the gesture conflicts with the user interaction on the text field. Wouldn't a button to the side of the textfield create a better user experience?
FWIW, here is the code to add a background UIView
using a double tap. a long press gesture had the same result
@IBOutlet weak var backgroundView: UIView!
@IBOutlet weak var textField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.myTextFieldTapped))
tapGesture.numberOfTapsRequired = 2
backgroundView.addGestureRecognizer(tapGesture)
}
@objc func myTextFieldTapped() {
print("Double tapped on textField")
}
