documentation - How to find out designated initialiser from Objective-C docs -

i'm extending uitableviewcontroller , want override designated initialiser might perform custom code.

i'm unable find reference designated initialiser in docs. how once find out information?

edit

i'm inferring docs - (id)initwithstyle:(uitableviewstyle)style designated initialiser, not explicitly state in terms. normal?

you can information in uitableviewcontroller.h. contains following code:

ns_class_available_ios(2_0) @interface uitableviewcontroller : uiviewcontroller <uitableviewdelegate, uitableviewdatasource>  - (instancetype)initwithstyle:(uitableviewstyle)style ns_designated_initializer; - (instancetype)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil ns_designated_initializer; - (instancetype)initwithcoder:(nscoder *)adecoder ns_designated_initializer; 

the ns_designated_initializer indicates it's designated initializer.
