I'm following this tutorial to create a project with ArcGIS API for iOS:

When I want choose the AGSMapView class , this doesn't appear in the list of class. Finaly when I built de project this failed.

This is the message of error: Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_AGSTiledMapServiceLayer", referenced from:
      objc-class-ref in ViewController.o

Anyone know what happening? Maybe a library is not linked?
