Close iOS Keyboard by touching outside ( a smarter way)

Question

I have UIViewController with UITextfield and several other elements (several subviews and buttons). I want to close the keyboard when tapped somewhere outside of the UITextfield .

I know there is an answer Close iOS Keyboard by touching anywhere using Swift , but this way doesn't work if user taps on viewController's subviews or buttons. I can add the similar UITapGestureRecognizer for each subViews and buttons, but is there a smarter way to resolve this?

Answer 1

extension UIViewController{
    open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.view.endEditing(true)
    }
}

Also if you have elements in a UIScrollView, add this method too:

extension UIScrollView {
    open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.next?.touchesBegan(touches, with: event)
    }
}
