the code start connection:
atconnect *connection = [atconnect sharedconnection]; connection.apikey = @"myapikey"; [connection presentmessagecenterfromviewcontroller:self]; when uncomment line apikey assign, there no error.
please me if can.
the problem apptentive uses categories, setup on nsmanagedobject, in system categories not getting loaded. issue difficult issue understand, , solution murky , dependent on version of xcode using.
to force categories load using sledge hammer, add "other linker flags":
-all_load if works, try better solution (changing "" real name:
-force_load $(build_products_dir)/<apptentive_library_name>.a if works, can try using flag:
-objc if search on site terms "all_load", "force_load", , "-objc" you'll find oodles of posts.
