title: Add "...Read More" to the end of UILabel
body: <p>I have a <code>UILabel</code> and in some cases the text is longer then the <code>UILabel</code> itself, so I see the text as <code>"bla bla bla..."</code> I want to add a <code>...Read More</code> button text at the end of the <code>UILabel</code>..</p>
  
  <p>I've read some posts but they offer solutions that are not good to me, for example: to calculate how many characters will enter the <code>UILabel</code>, but with the font i'm using each character has a different width.</p>
  
  <p>How can I manage to do that?</p>
  
  <p>Thanks in advance!</p>
