With this non-intrusive UIViewController extension, only a single line of code will make your scrollView auto resize when the keyboard appears. It literally cannot get easier than this, and you don't even need to subclass anything.

For a scrollView from nib or storyboard

@IBOutlet weak var scrollView : UIScrollView! override func viewDidLoad() { super.viewDidLoad() setupKeyboardNotifcationListenerForScrollView(scrollView) }

Just as simple if you want to use it with a tableView

@IBOutlet weak var tableView : UITableView! override func viewDidLoad() { super.viewDidLoad() setupKeyboardNotifcationListenerForScrollView(tableView) }

To remove observers for example in deinit

deinit { removeKeyboardNotificationListeners() }

SingleLineKeyboardResize is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "SingleLineKeyboardResize" 

It's only one file you need, 'UIViewController+Keyboard.swift', copy it into your project, and you are good to go.

Really good APIs should not need more than a single line of code to work and be as non intrusive as possible. This library is a part of my ongoing effort to build single line libraries for iOS. Check out the other ones on the list as well.
