-[NSNotificationCenter postNotificationName:object:] Can I pass nil for object?

StackOverflow https://stackoverflow.com/questions/6398974

Frage

Can I pass nil for the object argument of -[NSNotificationCenter postNotificationName:object:] since the observers don't care who the sender is, or is it better practice to pass self for the object argument even though the observers aren't checking who sent the notification?
