Attached custom google tile layer codes work fine with Arcgis iOS SDK v2.x. When upgrade to SDK v10.1, compile error: AGSTileOperation and AGSTile not found. It seems that these class/protocol are removed from SDK v10.1. I have read custom tile layer sample at (, but I don't know How to revise attached file to make it work in v10.1. 

Any tips? thanks.
