- only
View Controller
has Storyboard ID
- other view (eg:
UIButton
) no Storyboard ID
how get id
of a normal view (in Storyboard) ?
two method:
use Referencing Outlet
= normally is weak reference ~= like pointer
in C
eg: add reference for UIButton
in Storyboard -> choose your UIButton -> Right Click UIButton
-> Referencing Outlets
->New Referencing Outlet
-> drag it to ViewController.h
-> got notice Insert Outlet
-> popup window -> set Name
to you want, eg deviceNameBtn
-> Connect
-> auto generated code into ViewController.h



@property (weak, nonatomic) IBOutlet UIButton *deviceNameBtn;
then in you (Objective-C) code, you can use deviceNameBtn
as the ID
of UIButton
, do whatever you want
use (int
type) tag
eg: your UILabel
view's tag = 1

get your view:
UILabel *label = (UILabel *)[self.view viewWithTag:1];
