<AGSGPSInfoTemplateDelegate> Protocol Reference

---

Description

A protocol which must be adopted by any class wishing to display content in the callout window for the GPS location symbol . An instance of the class must then be set as the infoTemplateDelegate on the map's gps object.

The methods are optional. If the custom view method is implemented and does not return nil, then the other methods will not be called. This is because if a custom view is displayed in the callout then it is the only content in the callout.
