KeyboardMan

We may need keyboard infomation from keyboard notifications to do animation. However, the approach is complicated and easy to make mistakes. Even more, we need to handle the bug of system fire keyboard notifications.

But KeyboardMan will make it simple & easy.

Requirements

Swift 4.2, iOS 8.0

(Swift 3, use version 1.1.0)

Example

import KeyboardMan

Do animation with keyboard appear/disappear:

let keyboardMan = KeyboardMan()

keyboardMan.animateWhenKeyboardAppear = { [weak self] appearPostIndex, keyboardHeight, keyboardHeightIncrement in

    print("appear \(appearPostIndex), \(keyboardHeight), \(keyboardHeightIncrement)\n")

    if let self = self {

        self.tableView.contentOffset.y += keyboardHeightIncrement
        self.tableView.contentInset.bottom = keyboardHeight + self.toolBar.frame.height

        self.toolBarBottomConstraint.constant = keyboardHeight
        self.view.layoutIfNeeded()
    }
}

keyboardMan.animateWhenKeyboardDisappear = { [weak self] keyboardHeight in

    print("disappear \(keyboardHeight)\n")

    if let self = self {

        self.tableView.contentOffset.y -= keyboardHeight
        self.tableView.contentInset.bottom = self.toolBar.frame.height

        self.toolBarBottomConstraint.constant = 0
        self.view.layoutIfNeeded()
    }
}

For more specific information, you can use keyboardInfo that KeyboardMan post:

keyboardMan.postKeyboardInfo = { [weak self] keyboardMan, keyboardInfo in
    // TODO
}

Check the demo for more information.
