4) Why does AGSPoint lack a spatial reference property? It would be helpful, if that or AGSLocator had a spatial reference. This way programmers would know the projection of coordinates coming back to them. Plus, IPoint in the ArcObjects model has a spatial reference property.
[Nimesh] I�??m not clear about your question. You mean to ask why the spatial reference property of the returned location points (AGSPoint) is null or AGSPoint itself does not have a spatial reference property based on the doc (http://help.esri.com/en/ArcGIsmobile/9.4/apis/iPhone/Reference/Classes/AGSPoint.html)?
The AGSPoint does have a spatial reference property. If you change the code line (127 and 172) as following then you will see the location point�??s spatial reference information.
NSLog(@"Address Candidate @ (%f,%f,%@)",[location x], [location y], [location spatialReference]);
