Using Parse and Google Maps in the same app - conflict at linker flags -- iOS 7.1, Xcode 5.1

Question

I have an app where first time I used PARSE. Then for second update, client requested GoogleMaps . When setup GMS, it said: " Choose your project, rather than a specific target, and open the Build Settings tab. In the Other Linker Flags section, add -ObjC. If these settings are not visible, change the filter in the Build Settings bar from Basic to All. "

If I set -ObjC to linker flags, I have this kind of errors from parse:

Undefined symbols for architecture i386: "_FBTokenInformationExpirationDateKey", referenced from:

-[PFFacebookTokenCachingStrategy cacheTokenInformation:] in Parse(PFFacebookTokenCachingStrategy.o) -[PFFacebookTokenCachingStrategy expirationDate] in Parse(PFFacebookTokenCachingStrategy.o) -[PFFacebookTokenCachingStrategy setExpirationDate:] in Parse(PFFacebookTokenCachingStrategy.o) "_FBTokenInformationTokenKey", referenced from:

I found a solution to do not add Facebook in app and to use this kind of flag: -force_load

And after using this, I have also error: ld: file not found: clang: error: linker command failed with exit code 1 (use -v to see invocation)

I tried different types of using this, like : -force_load - the same error -force_load pathOfFramework/ - the same error

It is possible to give me a solution for this ?

Thanks a lot !

The problem is that parse has classes that it doesn't load if it doesn't need. For example, it only imports the Facebook classes if FacebookSDK is installed. -ObjC loads all of these, but they are dependent on FacebookSDK. When it can't find the files it needs, it throws errors:

Change:

-ObjC

To:

-force_load $(PROJECT_DIR)/GoogleMaps.framework/GoogleMaps
