Showing UIPickerView with selected row
<p>I am trying to figure out how to show the selected row when i open <code>UIPickerView</code> after it has been selected last time.</p>

<p>When I open my PickerView again, I want my <code>UIPickerView</code> to set selected row which I choose at last time.</p>

<p>Is there any way in Swift?</p>
