Accessing an IBOutlet from another ViewController in objective-c

Question

I'm trying to access an IBOutlet from my other view controller, I have tried importing them both;

#import "CreateTest.h" #import "SecondViewController.h" But when I try to access the IBOutlet; _SubjectValue.text = @"hi"; It returns an error saying "Use of undeclared identifier _SubjectValue"

If you're trying to access one view controller IBOutlet from another view controller this is not a good practice and proper way. Check out [this](http://stackoverflow.com/questions/28344336/how-to-access-an-iboutlet-from-another-class) everything is well explained — Mahbub Ahmed, Mar 12 '17 at 17:10

Make first class to delegate of second class. Then define IBOUTLET in delegate protocol. Then access it via delegate like so:

_delegate.yourIBOutlet.someProperty

If your very new I'd recommend some basic tutorials.

Edit: An instance of second class is required though. Depending if you're working with storyboard or not you ca receive/instantinate it in different ways.

If you are trying to access another class IBoutlet, first you have to create object of that class.

You're trying to access IBOutlet like this _SubjectValue.text = @"hi"; which basically means self.SubjectValue.text = @"hi"; but you'r second class don't have a IBOutlet name SubjectValue.text.

You have to access IBOutlet of another class through its object.Create a object of the class and then use this object to access the property/IBOutlet of that class

Hope it helps..

I don't know what you mean - I'm very new to iOS – Mar 12 '17 at 19:00 — , Mar 12 '17 at 19:00
