i need save value of uiswitch in viewcontroller b.

any appreciated.

don't try access view controller's view hierarchy directly. should treat view controllers views (and switch kind of view) private.

set ibaction on switch points owning view controller. in action save sate of switch property of view controller.

you can access property other view controller.
