ios - Add a view on top of the keyboard using InputAccessoryView

Question

I'm trying to add a uiview to be on top of the keyboard always. I did it first with KeyboardWillShow/Hide, but it dosen't cover all cases and I'm trying to use inputAccesoryView. this is what I tried:

private var accessoryView = UIView(frame: CGRectZero)

class ViewController : UIViewController {

    var myView: customUIView

    override var inputAccessoryView: UIView {
        return accessoryView
    }

    override func canBecomeFirstResponder() -> Bool {
        return true
    }

    override func viewDidLoad() {
       super.viewDidLoad()
       accessoryView = myView
    }
}

I get the following error :

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:UICompatibilityInputViewController should have parent view controller:MyViewController but requested parent is: UIInputWindowController: '

any help will be appreciated!

To get a view to stick above the keyboard, the code itself is pretty simple. The code you posted is not correct, try this (note that you must connect textField to the UITextField in your storyboard):

@IBOutlet weak var textField: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()

    let customView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 44))
    customView.backgroundColor = UIColor.red
    textField.inputAccessoryView = customView
}
