Keyboardy

Description

Keyboardy extends UIViewController with few simple methods and provides delegate for handling keyboard appearance notifications.

• Keyboardy is just wrapper on UIKeyboardWillShowNotification and UIKeyboardWillHideNotification notifications.
• Supports both AutoLayout and frame-based animations.
• Swift implementation.
• Without any hacks like method swizzling and magic numbers (ex., curve << 16).

Usage

• Import Keyboardy module

import Keyboardy

• Register for keyboard notifications

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

    registerForKeyboardNotifications(self)
}

• Unregister from keyboard notifications

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

    unregisterFromKeyboardNotifications()
}

• Implement KeyboardStateDelegate

extension ViewController: KeyboardStateDelegate {

    func keyboardWillTransition(_ state: KeyboardState) {
        // keyboard will show or hide
    }

    func keyboardTransitionAnimation(_ state: KeyboardState) {
        switch state {
        case .activeWithHeight(let height):
            textFieldContainerBottomConstraint.constant = height
        case .hidden:
            textFieldContainerBottomConstraint.constant = 0.0
        }

        view.layoutIfNeeded()
    }

    func keyboardDidTransition(_ state: KeyboardState) {
        // keyboard animation finished
    }
}
