Hi James,
I'd suggest that you're probably pushing the idea of decoupling things a bit
too far here.
View Controllers are inherantly tied to the behaviour of your application, and
your user's experience of the flow through it. In 95% of cases, it's
absolutely correct for the view controller to know "the user pushed this
button, therefore I should show them this other view controller".
For the 5% of remaining cases where (for example) you have a highly reusable
view controller that gets used in many different places in the app, and may
push a different child VC depending on its usage location, I'd suggest simply
using a delegate to that particular VC to allow you to separate out what gets
pushed.
Thanks
Tom Davie
