title: IPhone MapKit - Drop multiple pins simultaneously
body: <p>In my app i'm adding alot of pins and in <code>viewForAnnotaion</code> I set <code>animatesDrop=TRUE</code> on my <code>MKPinAnnotaionView</code>. The problem is that when having 200+ pins dropping one by one takes a long time. I have seen Apps that drops all pins at once and wonder how to do that. </p>
  
  <p>Let me know if i'm not clear.</p>
  
  <p>Thanks!</p>
