objectForKey:self

Subject: objectForKey:self

I've created a SIMBL hack that uses poseAsClass to swap in my own subclass of Safari's BrowserWindow class. Because poseAsClass doesn't allow you to add your own instance variables, I've stored them in a global NSDictionary.

The instance variables are then looked up by using the instance pointer as the key. Here's the strange part - I was using objectForKey:self, and it worked fine on my Powerbook, but seemed to break everywhere else. Replacing that with objectForKey:[NSNumber numberWithInt:self] seems to work fine, regardless of the environment.

Can anyone explain why objectForKey:self works in some places but not others?

Jon
