Hey Weydson -
NSDictionary equates keys by using -[NSObject isEqual:] and -[NSObject
hash], so a number with a different pointer address but the same value
as determined by isEqual: is fine.
If identity vs value does become an important distinction for you,
CFDictionary gives you control over that.
Good Luck -

Thanks all for the replies. I clearly understand now that I should use
NSNumber instead of NSInteger. However, another question came up:
when I use
the removeObjectForKey, how can I make a reference to a specific
key? Let's
say I want to remove key that was initialized with [NSNumber
numberWithInt:1]. If I call removeObjectForKey:[NSNumber
numberWithInt:1],
that method won't work because a new NSNumber pointer is being
created,
correct?The only solution I could find is to use enumeration and go
through
each key and gets its integer value.
Thank you

That's correct. You really shouldn't put any scalar types in an
NSDictionary (or any other container type in the Cocoa API.)
Not quite true. NSHashTable and NSMapTable are part of Cocoa API
and are
design to support NSInteger directly.
