MQMapKit (MapQuest) IOS 6 crashing

I had a working MKMapKit working in an app Im working on and decided to convert it to MapQuest's MQMapKit which is supposed to be a drop-in replacement from what I understand. After doing so (and checking for any 'MK' map stuff...which I dont believe I have any now, they are all 'MQ' map references), Im getting the following crash when the app tries to start up. Im not sure where 'prepareKeyForNewAnimation' comes from. It seems to me to be a MapQuest Library issue (which is version 1.0.1). Any ideas what is causing this or how to fix it? Thanks for any help on this!

[EDIT] Very bizarre. This was happening in the simulator on ipad. I tried plugging in my iphone 5 and I got a provisioning error (even though it worked earlier and shouldnt have been an issue. When I edited the dev profile and added a couple other users that I had and re-downloaded it, it still didnt work. When I went into the settings and changed the debug/release/distro settings to the generic 'Developer profile' for all three it now worked fine without crashing. Bizarre!

[EDIT] NOT so solved....still crashing on and off, mostly on. Any help would be appreciated.

[SOLVED] Found this article where I missed adding -ObjC to 'Other Linker Flags': mapquest developer site
