Access to an IBOutlet in a modal view's parent view

问题

I have an iOS app where my architecture is:

VC1 => MVC1

I want to access to an VC1's IBOutlet (aboutBtn). I tried making a delegate in MVC1 and setting VC1 as delegate, but I still can't access it. How would I do it?

回答1:

I would just create an instance variable in MVC1 and pass the IBOutlet variable you're trying to access from VC1 to MVC1. For example, you could call something like MVC1.referenceToSomeIBOutlet = self.someIBOutlet from VC1. That will give MVC1 access to the passed in IBOutlet object.
