title: iPhone: How to make a tip balloon programmatically?
body: <p>Please provide the code to make a tip balloon programmatically, like Grindr has.</p>
  
  <p>I want it to be sized automatically, based on the text &amp; font-size.
  And, I want to be able to change the location of the arrow.
  If it's on an end, it should be a right triangle. Otherwise, it should be an eqilateral triangle.</p>
