ios - Data passed to prepareForSegue is nil -

i'm trying ingredientviewcontroller update array belongs controller called via segue (fridgeviewcontroller)

in ingredientviewcontroller fridgemanager nil no matter try

the code:

fridgeviewcontroller:

- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     // new view controller using [segue destinationviewcontroller].     // pass selected object new view controller.     ingredientviewcontroller *controller = (ingredientviewcontroller *)segue.destinationviewcontroller;     [controller setfridgemanager:fridgemanager]; } 

ingredientviewcontroller:

@property (strong, nonatomic) fridgedatamanager *fridgemanager; 

and in viewdidload fridgemanager nil (and in other method of coarse)

synthesize fridgemanager property in ingredientviewcontroller.m

@synthesize fridgemanager;
