ios - Use UILabel in Class Method -

so have this:

@interface viewcontroller : uiviewcontroller{     iboutlet uilabel *screen; }  +(void)num:(int)number;

and want access screen in class in num method so:

+(void)num:(int)number{     screen.text = @"test"; }

but xcode says

"instance variable 'screen' accesses in class method"

is there way this?

yes, reason not letting because + sign in method denotes class method aka called on viewcontroller class don't have reference specific screen outlet.

change + - , able call method like

[self num:7]

and access screen outlet in method

hope helps!
