How to disable keyboard on specific textField but allow picker view as input Swift?

Question

I have 2 textFields in a view controller one uses a pickerView as input and the other uses a keyboard, the problem is the keyboard is still enabled under the pickerView. I have it set up that when the textfield in the bottom is being used the keyboard moves the view up to make the textField visible but when i click on the top textField which uses the pickerView it also moves the view up and you can't see the input on that textField. I need to only use the pickerView on top textField so the view won't move up when that textfield is being used. Here is what i'm using to move view up:

func keyboardWillShow(notification: NSNotification) {

    bottomConstraint.constant = 200
    topConstraint.constant = -200
    UIView.animateWithDuration(0.3) {
        self.view.layoutIfNeeded()
    }
}



func keyboardWillHide(notification: NSNotification) {

    bottomConstraint.constant = 8
    topConstraint.constant = 10
    UIView.animateWithDuration(0.3) {
        self.view.layoutIfNeeded()
    }
}

Here is my setup for the pickerView in viewDidLoad: (colorCodePicker is the textField with pickerView as input)

let pickerView = UIPickerView()

    pickerView.delegate = self

    pickerView.backgroundColor = UIColor.whiteColor()

    colorCodePicker.inputView = pickerView

I have tried most of the solutions here but haven't got any to work i.e. if i disable user input than i can't call the pickerView, also tried inserting a clear button over the textField like one of the suggestions with no luck. Or maybe a solution to only move view up when bottom textField is active, any ideas?

Answer 1

In both keyboardWillShow and keyboardWillHide check if colorCodePicker.isFirstResponder() to decide whether to change the constraint.
