I am having the error and it is AdMob crashes with [GADObjectPrivate changeState:]: unrecognized selector. I know I need to add -objC but if I add, the following consequences occur.
Consequence I am using Parse SDK and now I don't need to add facebook SDK (because I don't use -objC). If I add facebook SDK, there are many other problems occur and it might need not to support iphone 3gs, 4,etc.
As a result, I need to know a way to solve this problem without adding -objC and also -all_load. I would like to know how to do.
I have found out a way to do.
Instead of using -objC, I can set to the required library only by using this.
-force_load <library file name>
So, -objC isn't required.
