Question

[[NSNotificationCenter defaultCenter] postNotificationName:kNotificationForbidAdvPost object:nil];

I define postNotificationName:kNotificationForbidAdvPost in a .h file

Im my subclass of NSApplication, I import this .h file. And have a observer of this Notification

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(changeToRecordingStatus) name:kNotificationForbidAdvPost object:nil];

I am sure that the observer was added first, and then post the notification.

And I see the [UINotification default] in Debug. It have same memory address in two part of code.

Is there some mistake I have?

Thanks!

Answer 1

I have try that add a arugument, but it is still not worked.

I create a new project and use a no-argument function to response Notification, it is worked normally.

The reason why I cannot receive the Notification is that a removeObserver method was called at one part which I didn’t notice.

Thanks for all your reply.
