#iPhone GeoSpoof ##What this is We all know the iPhone simulator is all but useless for testing location based code. To remedy this, I’ve created a simple simple Objective-C category that you can use to simulate location changes. It’s not over engineered. You don’t have to go figure out a weird file format then edit that file to get it to work. Just program your routes.

##How to use it There are two very simple approaches you can take. One is easier upfront, and one is better in the long run.

Quick & Dirty way

1. Import the the .h and .m files into your project.
2. Comment the #ifdef SPOOF and #endif directives when you want to spoof

Better

1. Import the .h and .m files into your project.
2. Duplicate one of your testing build configurations
3. Define SPOOF in the Preprocessor Macros section of the build settings of the newly duplicated configuration.

This way is better because you set it up once, and don't need to rely on your memory. You wouldn't want to have forgotten to uncomment the #ifdefs in a production app would you?

##How it works It replaces the startUpdatingLocation and startMonitoringSignificantChanges methods in the system's CLLocationManager class. The new implementations call locationManager:didUpdateToLocation:fromLocation: on the location manager's delegate.
