Message with sender and object

I don't seem to know how to send a notification with an object and a sender.

I can send a notification with the name, sender and user information. Cm:

- (void)postNotificationName:(NSString *)notificationName
                      object:(id)notificationSender
                    userInfo:(NSDictionary *)userInfo

And I can publish NSNotification with the object, but not associate the sender with it:

NSNotification *notification = [NSNotification notificationWithName:name
                                                             object:someObject];
[[NSNotificationCenter defaultCenter] postNotification:notification];

Can someone tell me how to send a notification with (a) the object and (b) the sender’s link?

In both methods that you suggest, the variable objectrepresents the sender of the notification, and this can be anything. To provide additional objects with a notification, you can transfer the dictionary with your objects to userInfo.

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                                      someObject, @"someObject",
                                      anotherObject, @"anotherObject", nil];
[[NSNotificationCenter defaultCenter] postNotificationName:name
                                                    object:sender
                                                  userInfo:options];
