undefined methods

I'm using the b开发者_StackOverflow中文版ignerdranchguide and having similar issues witha lot of my projects.

I'm trying to figure out why my code [mp setRegion:region] says "Method '-setRegion' not found (return type is 'id'). I have used the and I used the same library for another project that used it to identify map information.

In another project, I'm using the accelerometer. In the delegate method (there is only one) it says my [accel x] message is undefined. The accelerometer should be part of the UIKit framework but doesn't seem to work. I copied it off a book but it might have something to do with the new ios.

Thanks for you help.
