iphone - NSDictionary variable not being passed to other methods -

i have method takes nsdictionary viewcontroller , assigns global nsdictionary (carddictionary) variable in requestmodel class. carddictionary declared property (nonatomic, retain) , synthesized. works ok (as verified nslog). here is:

-(void)findindexforcardpage:(nsdictionary*)dictionary  { //parse here , send global dictionary self.carddictionary = dictionary; nslog(@"%@",carddictionary); } 

now when try access variable in method, still in requestmodel class, null:

-(nsdictionary*)parsedictionaryforcardpage  { //parse dictionary here data needed on card page nslog(@"%@",carddictionary); return carddictionary;  } 

this method called viewcontroller class, , carddictionary null. how can make carddictionary retain data previous method? tried taking out self self.cartdictionary...no luck. else should know?

if saying carddictionary global variable, , self.carddictionary - accessing instance variable.

and in

-(nsdictionary*)parsedictionaryforcardpage  { //parse dictionary here data needed on card page nslog(@"%@",carddictionary); return carddictionary;  } 

you accessing global one. delete , use instance variable.
