one of my view controllers has several UISwitches, and I want another view Controller to be able to access the values of the UISwitches for If/and statements. How do I do this in Objective-c?
You probably don’t want to do that. If you want a second ViewController to have different behavior based on switches thrown in the first, you should just bind the switches to User Defaults, which you can read anywhere in your app.
