title: How to word wrap text in annotation subtitle
body: <p>I tried to insert return and newline chars into the subtitle string, but they ended up as "spaces" and not line breaks. Since subtitle is simply an NSString I must look at the container, which likely means I'll have to roll my own annotation views.</p>
  
  <p>The NSString do become f.ex. "90510\nHollywood, CA", but maybe I have to 'encode' the newlines instead, or use a subclass of NSString to send to subtitle?</p>
  
  <p>What baffles me is that surely, subtitle should be able to "be wrappable", as the MKAnnotation(view) handles too long text by resizing the bubble and adding "...", et cetera.</p>
  
  <p>I do need proper word wrap (and not hard line breaks) for a paragraph of text I'm adding later, but I could possibly do that as a separate alert or modal box type, if you know which ones support word wrap I'd be grateful if you could suggest them.</p>
  
  <p>A hunch is that something could be possible by adding a UILabel as a subview, or somehow access the UILabel(?) that is used to display the subtitle, and set its numberOfLines to 0, but I don't know how to do the latter.</p>
