While searching forums i found, that it could be a problem of CoreData, that Apptentive SDK uses, but as i write, i'm new in iOS developing, so i didn't use CodeData till now.
The code to start connection:
ATConnect *connection = [ATConnect sharedConnection];
connection.apiKey = @"myApiKey";
[connection presentMessageCenterFromViewController:self];
When i uncomment a line with apiKey assign, there is no error.
Please help me if You can.
The problem is that Apptentive uses categories, like setup on NSManagedObject, but in your system those categories are not getting loaded. This issue is a somewhat difficult issue to understand, and the solution is murky and dependent on the version of Xcode you are using.
To force categories to load using a sledge hammer, add this to your "Other linker flags":
-all_load
If that works, then try this much better solution (changing "" to its real name:
-force_load $(BUILD_PRODUCTS_DIR)/<apptentive_library_name>.a
If that works, then you can try just using this flag:
-ObjC
If you search on this site for the terms "all_load", "force_load", and "-ObjC" you'll find oodles of posts.
