Is there some way to get UIKeyboard size programmatically. 216.0f height and 162.0f height in landscape.

Answer 1

On swift 4

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self, selector: #selector(getInfo(notif:)), name: .UIKeyboardDidShow , object: nil)
}

and then:

@objc func getInfo(notif: NSNotification) -> Void {  
    guard let userInfo = notif.userInfo else {return}

    if let myData = userInfo["UIKeyboardFrameBeginUserInfoKey"] as? CGRect {
        print(myData.width)
        print(myData.height)
    }
}
