I just included AWSIOSSDK.framework and Facebook SDK together in my project, then got a build error:

> 
> ld: duplicate symbol \_OBJC\_METACLASS\_$\_SBJsonParser in /Users/tom8/Desktop/site1/site1/facebook-ios-sdk/libfacebook\_ios\_sdk.a(SBJsonParser.o) and /Users/tom8/Desktop/AWSiOSSDK.framework/AWSiOSSDK(SBJsonParser.o) for architecture i386

I use iOS Facebook SDK Static Library, so i could not simply delete sbjson files in facebooksdk folder. I also tried to delete sbjson files in AWSIOSSDK folder, but it also did not work. Could someone give me some advice?
