iphone - initializing viewcontroller(piechartController) to viewcontroller's(covVC) variable -

i doing following initialize viewcontroller(piechartcontroller) viewcontroller's(covvc) variable following …is right change view controller variable ?

  self.pie = [[chatcontroller alloc] initwithnibname:@"chat" bundle:nil]; self.covvc = [[coverassetcontroller alloc] init]; self.covvc.pieobj = self.pie; 

coverassetcontroller.h------>

 @interface coverassetcontroller : uiviewcontroller {       chatcontroller *pieobj;  } 

you need add property in coverassetcontroller :

 @interface coverassetcontroller : uiviewcontroller {      piechartcontroller *pieobj;   } @property(nonatomic, assign) piechartcontroller *pieobj; 

and in implementation add :

@synthesize pieobj; 

anyway, it's ok ^^ in fact depends want etc etc.
