access object passed in NSNotification?

Question

I have a NSNotification that is posting a NSDictionary:

 NSDictionary* dict = [NSDictionary dictionaryWithObjectsAndKeys:                                           anItemID, @"ItemID",                                           [NSString stringWithFormat:@"%i",q], @"Quantity",                                           [NSString stringWithFormat:@"%@",[NSDate date]], @"BackOrderDate",                                           [NSString stringWithFormat:@"%@", [NSDate date]],@"ModifiedOn",                                           nil];                      [[NSNotificationCenter defaultCenter] postNotification:[NSNotification notificationWithName:@"InventoryUpdate" object:dict]]; 

How do I subscribe to this and get information from this NSDictionary?

in my viewDidLoad I have:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(recieveInventoryUpdate:) name:@"InventoryUpdate" object:nil]; 

and a method in the class:

- (void)recieveInventoryUpdate:(NSNotification *)notification {     NSLog(@"%@ updated", [notification userInfo]); } 

which logs a null value of course.

Answer 1

it's [notification object]

you can also send userinfo by using notificationWithName:object:userInfo: method
