iPhone view architecture question

So I have (for instance) three views:

A: root view

B: a view functionally identical to root

C: a data entry v开发者_StackOverflowiew which collects a few piece of info

What I'm trying to do is reuse C to supply the data it collects to either A or B. It should supply the data to whichever of the two it is pushed onto. The data for A is similar, but functionally distinct, to what collects for B.

Right now, I'm passing data from C to A or B via a singleton class. What I'm trying to avoid is having two instances of C, one to supply data to A and B (because, in actuality, the program will have 5 total views like C.

Does the question make sense?

use protocol/delegates. on the save of your viewcontroller c, call the delegate that initially pushed c and passed the data along with it. In the implementation of the protocol in a or b, do your saving with the passed in value.

Firstly it should be your view controllers getting data and not your views, the view controllers will feed in data to their views accordingly...Now assuming root view controller A knows of the rest of the view controllers (B C D E) then i would suggest to define a protocol in view controller C that root view controller A can conform to, that way u can pass data to A, and from A you can distribute the data onto to B since A is your root controller which knows of all the other controllers... hope that helps
