For one particular text field, I need it to show a picker from which the user can pick state names, once the user has picked a state by clicking on the states name, the picker should disappear. I am not quite sure how to do this, I have made the Nib file which looks like this.

I've already seen two similar questions to mine, but the answers for those questions do not work for me. I have an old project with a list of countries manually typed out inside a set of square brackets. I can easily use this in my pickerView but I'm wondering if there is a more efficient way to do this? I will be using the list of countries in a UIPickerView.
