title: Add a picker view at the bottom of the screen in a tableview controller
body: <p>I have a tableview controller with many statics cells. When i click on one field, i want to display a UIPicker to pick a value. </p>
  
  <p>My table is big, so it's scrollable. </p>
  
  <p>How can i add a subview on my tableviewController to display this UIPicker at the bottom of the ipad screen, i mean not at the bottom of the tableview.</p>
  
  <p>Thank you.</p>
