Facebook Like Button - can´t build archive with the new feature FBLikeControl - ios

Question

I want to integrate Facebook like Button with the new feature FBLikeControl. On the facebook page they have written it is only for developement and not for publication on the AppStore.
Here is the Tutorial from facebook https://developers.facebook.com/docs/ios/like-button/
When I want to build an archive with my code I get the error message "Use of undeclared identifier FBBetaFeaturesLikeButton".
Is there a way to solve this problem or if there's any other alternative solution, I would appreciate that.
Here is my code:
[FBSettings enableBetaFeature:FBBetaFeaturesLikeButton];
[FBSettings enablePlatformCompatibility:NO];
FBLikeControl *like = [[FBLikeControl alloc] init];
like.frame = CGRectMake((self.frame.size.width-like.frame.size.width)/2, facebookY, 60, 20);
like.objectID = #"https://www.facebook.com/pages/abcdefgh/123456789?ref=tn_tnmn";
[self addSubview: like];

This link says:
FBLikeControl is a preview feature and may not be deployed to the App
Store. Only developers and testers of your Facebook app will be able
to use the Like Button.
is the reason you are unable to built the archive.
There are several ways to implement like, the one which worked for me is as follows:
[FBRequestConnection startWithGraphPath:#"/object-id_to_like/likes"
parameters:nil
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
// Handle error here
}];
Here is the Link
EDIT: It is pretty simple, you just have to replace FBLikeControl code in your project with the above method call replacing object-id_to_like to the actual post-id/ object-id. What the method does is it POSTS a like on corresponding object/post.
In case you have problem to fetch the object id of the object/post you can fetch it using same method with the HTTPMethod parameter set to #"GET". Following code will return posts from your timeline:
[FBRequestConnection startWithGraphPath:#"/me/home"// you can change this to #"/me/feed" if required
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error ) {
if (!error){
// Fetch Post-id/Object-id here
}else{
// handle error here
}
}];
