detect if user touch outside keyboard

Question

I implemented this function to detect touches outside keyboard and hide the keyboard

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }

but how can I do callback when a user touches outside the keyboard? I want another action to happen. I don't want only the keyboard to be hidden.I want to do other function including hiding keyboard everytime the keyboard is hidden I wa=ish to have more actions.

It's super easy. just need to create a function inside the viewcontroller that you want to call and add UIViewController.dismissKeyboard() in it

@objc func dismissKeyboardAndOtherStuff(){
 UIViewController.dismissKeyboard()
 // do other stuff

}

in you extension change the selector to reflect your new function

        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboardAndOtherStuff))

I did this but the other stuff will be executed once. – AlmoDev Dec 13 '17 at 07:04
Will be executed once every time you tap outside. Your wording is ambiguous explain what you want to achieve – Andras M. Dec 13 '17 at 07:31

I usually create an extension for this case:

extension UIViewController {
    func hideKeyboard() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }

    func dismissKeyboard() {
        view.endEditing(true)
    }
}

Basically you add a gesture to the view

and you can call it from any ViewController like this:

hideKeyboard()
