Simplifies iOS keyboard handling.

To use KeyboardController, simply initialize it with an array of UITextField objects.

let fields = [field1!, field2!, field3!, field4!, field5!]
self.controller = KeyboardController(fields: fields)

You can interact with KeyboardController directly via the following methods:

func moveToNextField()
func moveToPreviousField()
func closeKeyboard()

KeyboardController, depending on a returnKeyType property of an UITextField instance, will:

• UIReturnKeyNext - move to next text field
• UIReturnKeyDone - close keyboard

You could also take advantage of delegation methods:

func controllerDidHideKeyboard(controller: KeyboardController)
func controllerDidShowKeyboard(controller: KeyboardController)
func controllerWillHideKeyboard(controller: KeyboardController)
func controllerWillShowKeyboard(controller: KeyboardController)

by setting a delegate property of a KeyboardController:

self.keyboardController.delegate = self;

There is also an option of setting a textFieldDelegate property of all textFields that are under control of KeyboardController:

self.keyboardController.textFieldDelegate = self;

This could be particulary useful if you would like to add individual behaviour to UITextFields objects.

func textFieldDidBeginEditing(_ textField: UITextField) {
    if (textField == self.field4) { self.moveViewBy(-10) }
    if (textField == self.field5) { self.moveViewBy(-200) }
}

func textFieldDidEndEditing(_ textField: UITextField) {
    if (textField == self.field4) { self.moveViewBy(10) }
    if (textField == self.field5) { self.moveViewBy(200) }
}
