KeyboardObserver

public protocol KeyboardObserver

Subspec: Utility/KeyboardObserver

override func viewDidLoad() {
    super.viewDidLoad()
    addRecognizerForKeyboardDismissal()
}

To hide the keyboard when the user taps on the view add the addRecognizerForKeyboardDismissal to the viewDidLoad function.

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    addKeyboardObservers()
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    removeKeyboardObservers()
}

Add the keyboard observer functions to viewWillAppear and viewWillDisappear respectively. Adding them will allow the view controller to call the functions below when the keyboard is shown or hidden.

override func keyboardWillShow(notification: Notification) {
    // Handle keyboard will show action
}

override func keyboardWillHide(notification: Notification) {
    // Handle keyboard will hide action
}

The functions above will be called when the keyboard is shown or hidden.
