passing info between view controllers 33 answers

is there way create nsobject , set values in 1 view controller, , them in view controller looking existing instance of nsobject?

i created view controller instantiates model object , fills properties. how access instance of model object view controller?

i'm not asking how pass info in view controller calls view controller. know how that. i'm asking how set values model object different, unrelated , hierarchically independent view controllers.
