Can't link connector from UIImageView declared as an IBOutlet in a class to the corresponding UIImageView on the View Controller in storyboard

问题

This question is a follow up to: Can't link connector from IBOutlet to View Controller

I would now like to link another object of UIImageView called image, defined in class B to the same UIImageView on the ViewController. I wasn't able to do this using the same method. I imagine this is because, the UIImageView on the ViewController is now of custom class B, and the object image is an instance of UIImageView. I tried to cheat xcode by changing back the custom class of the UIImageView to UIImageView; doing that not only gave me an exception but I also couldn't see the object 'image' in the black box anymore. Any suggestions?
