Hi,

Several approach possible. The most easy is to give each pushpin an exclusive name, then you can use FindPushPin();. If you know the location and want to see if a pushpin is there you can use ObjectsFromPoint() or FindNearby(). Also you can keep a list of all the pushpins in an array in your application. Using the latter you have it all in control yourself, and it will be probably faster also.
