Hey all,

I have some json data to parse in my project. I downloaded the json-framework from Google and imported it into my project (Classes\JSON). When compiling the project, I received the following error message:

ld: duplicate symbol .objc_category_name_NSObject_NSObject_SBJSON in /Users/GeoPlanner/Library/SDKs/AGSiPhone/iphonesimulator.sdk/usr/local/lib/libAGSiPhone.a(NSObject+SBJSON.o) and /Users/GeoPlanner/Documents/MyFirstMapApp/build/

Has anybody experienced a similar problem? I guess AGS sdk is using the same json framework, but I can't figure out how to refer to the existing header file. I am fairly new to the iphone development. Any comment or suggestion would be appreciated.
