We may need keyboard infomation from keyboard notification to do animation. However, the approach is complicated and easy to make mistakes.

But KeyboardMan will make it simple & easy.

Swift 2.0, iOS 8.0

(Project with Swift 1.2 can still use version 0.4)

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 strongSelf = self {

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

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

keyboardMan.animateWhenKeyboardDisappear = { [weak self] keyboardHeight in

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

    if let strongSelf = self {

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

        strongSelf.toolBarBottomConstraint.constant = 0
        strongSelf.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.

Feel free to drag KeyboardMan.swift to your iOS Project. But it's recommended to use CocoaPods or Carthage.

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.3.16 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ [sudo] gem install cocoapods

To integrate KeyboardMan into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'KeyboardMan', '~> 0.5'

Then, run the following command:

$ pod install

You should open the {Project}.xcworkspace instead of the {Project}.xcodeproj after you installed anything from CocoaPods.

For more information about how to use CocoaPods, I suggest this tutorial.

Carthage is a decentralized dependency manager for Cocoa application. To install the carthage tool, you can use Homebrew.

$ brew update
$ brew install carthage

To integrate KeyboardMan into your Xcode project using Carthage, specify it in your Cartfile:

github "nixzhu/KeyboardMan" >= 0.5

Then, run the following command to build the KeyboardMan framework:

$ carthage update

At last, you need to set up your Xcode project manually to add the KeyboardMan framework.

On your application targets’ “General” settings tab, in the “Linked Frameworks and Libraries” section, drag and drop each framework you want to use from the Carthage/Build folder on disk.

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script with the following content:

/usr/local/bin/carthage copy-frameworks

and add the paths to the frameworks you want to use under “Input Files”:

$(SRCROOT)/Carthage/Build/iOS/KeyboardMan.framework

For more information about how to use Carthage, please see its project page.
