Question

in my code I have created a Category over UIViewController, so that every of my UIViewControllers has a error handling method. Unfortunatey now whenever I call this method from the category I get the following warning in XCode:

 'MainWindowViewController' may not respond to '- (...method name...):'

We try to have our code without any warnings, so I wonder if there is any clever way to keep the Category and get rid if the “may not respond to” warning”.

Thanks for your help!

Answer 1

Importing the header where your category is declared to implementation file where methods from that category are used should eliminate that warning.
