Get currently selected value of UIPickerView

I have been googling how to get the currently selected value in UIPickerView, but everywhere it's mentioned using row:0 and so on.

I have a UIPickerView populated with string values like "One","Two", etc.

Now when I select a value to let's say "Two", is there anyway I can get this text.

Like in UITextView where it is _textview.text
