title: MKMapView detect when click in annotation balloon
body: <p>There is any way to detect the click in the annotation balloon? I wanted that when user do click in a annotation, it will show some information and if the user want to see all the information he should do click again in the balloon (like Android). I have found how to implement</p>
  
  <pre><code>-(void)mapView:MKMapView*)mapView didSelectAnnotationView:MKAnnotationView *)view
  </code></pre>
  
  <p>but nothing about what I want to do, so is it possible?</p>
