title: Get currently selected value of UIPickerView
body: <p>I have been googling how to get the currently selected value in UIPickerView, but everywhere it's mentioned using row:0 and so on. </p>
  
  <p>I have a UIPickerView populated with string values like "One","Two", etc. </p>
  
  <p>Now when I select a value to let's say "Two", is there anyway I can get this text.</p>
  
  <p>Like in UITextView where it is _textview.text</p>
