title: UIPickerView get "Clicked" Element?
body: <p>im using a rotated UIPickerView to use it horizontal.
  This works fine so far.</p>
  
  <p>Now i want to get the View/Title of the "clicked" UIPickerView row.
  The Delegate gives me the opportunity to get the "selectedRow" when the Picker
  selects a row. I want no event while selecting it i need the event of clicking it.</p>
  
  <p>The funny thing is, i can already click the elements. i added no button or anything else.
  the "clicked" elements/row get highlighted like a button. But where should i attach the event listener? or how can i get any of this events?</p>
  
  <p>i also tried to add buttons as view to the uipickerview. This works so far, but i can not click any button.</p>
  
  <p>Do i need a button as View in a UIPickerView row to get the touchupinside-event or
  can i use the normal row-element of a UIPickerView to get such an event?</p>
  
  <p>thx for any help!</p>
