Label on all markers?

Hi all, I am writing a function in the app which shows POI. I would like the name of the POI (e.g. restaurant name) appear on the markers. As far as I know there are only 2 ways to shows the balloon (i.e. can only shows balloon one at a time):

  • Automatically, if the annotation is tapped on the map.
  • Calling the Marker#select() method.

I would like to know if there are any ways to achieve it ?

Thank you
