Using object from one class in another

I have a two UIViewControllers, on one of which I want a custom button to be displayed. I have written the code for this. I have also written the code for a popover segue to the other ViewController, and as both controllers belong to my 'ViewController' class, the button is also displayed on the second ViewController, which I do not want.

Obviously I can create another class and make my second ViewController a member of this class, however I want the code for my second ViewController to change the colour of the button in the first ViewController, so how can I use an object from my first class in the second class implementation file?

Why don't you make few property private in first cass so that it doesn't get inherited.

Your main problem is to access object of ClassA from ClassB.

Here are a lot of ways, and answers here, to do :

Update a label through button from different view

Xcode - update ViewController label text from different view

Setting label text in another class

Set label on another view to stored NSDate
