<AGSInfoTemplateDelegate> Protocol Reference

---

Description

A protocol which must be adopted by any class wishing to display content for an AGSGraphic in the callout window. An instance of the class must then be set as the infoTemplateDelegate on the graphic.

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.

Defined in:

AGSInfoTemplateDelegate.h ( ArcGIS library)
