improper url causes app to crash

HamzaHaroon — Tue, 15 Jan 2013 13:20:59 GMT

When loading services, if the url is not case sensitive for the "MapServer" suffix, my app crashes if it tries to load the service. is there a way to try and catch failed map service load? or catch this error

You should adopt AGSLayerDelegate protocol, set layer's delegate to the class where you adopted the protocol and then try to listen to the methods, layerDidLoad: and layer:didFailToLoadWithError: to catch whether the layer is loaded successfully or there is any error.

i tried :

self.dynamicLayer.delegate = self; (dynamicLayer is of AGSDynamicMapServiceLayer)
and
self.tiledLayer.delegate = self; (AGSTiledMapServiceLayer)

but i get warnings saying incompatible pointer types.

i am adopting the AGSMapViewLayerDelegate, and the AGSLayerDelegate in my class header

it seems my error happens when i try to connect to a mapserver folder that is empty. I get an NSRange exception saying index range 0 out of bounds for empty array
