NSNotificationCenter: Do objects receive notifications on the same thread they are posted?

Question

I am interested in knowing whether I can expect the observing object\'s method to be pushed onto the stack before the posting object\'s method has been completed and removed

Answer 1

Just bothered to look it up myself, shameful:

From the class reference: NSNotificationCenter posts all notifications synchronously

Also, if you prefer, you can use NSNotificationQueue to post notifications asynchronously
