Jeremy’s Little Corner Of The Web…

I had a need tonight to observer all notifications being posted inside an application… it turns out it's pretty simple.

You first need to set your object up as an observer:

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

Note that the (notification) name is set to 'nil'.

Then you need to add the selector to actually log the notifications:

- (void)log:(NSNotificationCenter *)note {
NSLog(@"note = %@", note);
}

… and that's it!

I actually found the code to do this (or something like it) on this page at CocoaDev, so the credit goes to whoever wrote it there.
