title: IOS8. Close UIPickerView on selection click swift
body: <p>I do have a UIPicker view populated with selection options. I select on of them and click but <code>UIViewPicker</code> doesn't close. How do I close it or at least fire the event so that I could hide it programatically? </p>
  
  <p>I looked at <code>UIPickerViewDelegate</code> but haven't found any suitable method which would execute not on item selection but only when I click selected item.</p>
  
  <p>Thanks for any help!</p>
