How to pass variables between a complex navigational stack?

One common way is to define a protocol in the sub view controller for callbacks, and have each of the main view controllers implement that... when they create or call up the sub view controller, they tell it that they are the selection delegate to be called when a change is made. Then they can also choose to dismiss the sub view controller.

I need to look into callbacks as its not something I have done before. – C. Johns Sep 8 at 22:59 You usually pass information on which cell initiated the call into the sub-vc (either an object or the row that called up the sub view).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
