I am trying to set ontouch listener on UITextField but it not working at all here is my code:
class SettingsVC: BaseVC {
@IBOutlet weak var languageField: SkyFloatingLabelTextField!
@IBOutlet weak var btnburgerMenu: UIButton!
@IBOutlet weak var headerLbl: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
languageField.addTarget(self, action: "myTargetFunction:", for: UIControlEvents.touchDown)
}
func myTargetFunction(textField: SkyFloatingLabelTextField) {
print("test")
}
}
Here is the error I have
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[IFO.SettingsVC myTargetFunction:]: unrecognized selector sent to instance 0x7fac8b61ff30'
What's the reason of the exception?
It should be like so -
languageField.addTarget(self, action: #selector(YourViewController.myTargetFunction(sender:)), for: UIControlEvents.touchDown)
or use like
languageField.addTarget(self, action: #selector(self.myTargetFunction(_:)), forControlEvents: .touchDown)
and call the function like
func myTargetFunction(_ textField: SkyFloatingLabelTextField) {
print("test")
}
.touchDown is actually quite useless as it doesn't always fire. I needed a way for dialog to appear every time UITextField was touched. I used this instead:
class DateTextField: DefaultTextField, UITextFieldDelegate {
...
override init() {
super.init()
self.delegate = self // delegate to handle textFieldShouldBeginEditing below
inputView = UIView() // disable the input view
}
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
// Code to display my date picker dialog
return false // return false to disable textfield editing
}
}
