Step three: Making the connection

…The Photos Table View Controller needs to be…able to hold a reference to several photo objects,…and I'm going to do that all in code…rather than loading them in from some external file.…We'll load in the photos, but they're already saved in our asset catalogue.…So I'm going to jump to the implementation file for the Photos Table View Controller.…And up towards the top here, I'm going to create an array that can actually hold…these photo objects.…So I'll put some curly braces just after my @sign…interface, the class extension to make these just private instance variables.…

This'll just be a mutable array that we can add different objects to.…And while we're going to hold an array of…photo objects in the table view, we'll need to be…able to pass single photo objects, first to the…Display View Controller, and then to the Info View Controller.…So, what I'm going to do is just jump first into the display view…controller header file and inside its interface…part because this does need to be public.…I'm going to add just a reference to something called current photo.…
