title: IBOutlet UILabel do not get resized
body: <p>HI all,</p>
  
  <p>I have designed a view in Interface Builder and connected correctly with its controller.
  There some UILabel in it that are going to be filled with lot of text.
  But, even if I have declared "word wrap" and set line to 0 in IB, I can display only first line. I notice that if I increase the height of the UILabel in IB, all the text display properly in multi line, but I cannot do that because text may vary.</p>
  
  <p>Shouldn't the UILabel resize itself to fit all the text ?
  Also, if I built the UILabel programmatically I can succesfully accomplish a word wrap, why cannot do the same with IB ?</p>
  
  <p>What am I doing wrong ?</p>
  
  <p>thanks
  Leonardo</p>
