I want to get the type of NSNumber instance.

I found out on http://www.cocoadev.com/index.pl?NSNumber this:

 NSNumber *myNum = [[NSNumber alloc] initWithBool:TRUE];

 if ([[myNum className] isEqualToString:@"NSCFNumber"]) {
  // process NSNumber as integer
 } else if  ([[myNum className] isEqualToString:@"NSCFBoolean"]) {
  // process NSNumber as boolean
 }

Ok, but this doesn't work, the [myNum className] isn't recognized by the compiler. I'm compiling for iPhone.

Change NSNumber value by allocating new NSNumber?

as seen on Stack Overflow - Search for 'Stack Overflow'
I understand that NSNumber is immutable, but I still have the need to change it in my app. I use it because it's an object, and therefore usable with @property (if I could, I would use float or CGFloat in a heartbeat, but sadly, I can't). Is there any way to just overwrite the old NSNumber instance… >>> More

Can I use an NSDecimalNumber anywhere that an NSNumber is expected?

as seen on Stack Overflow - Search for 'Stack Overflow'
NSDecimalNumber is a subclass of NSNumber, and from what I can tell, it implements all of the NSNumber methods as expected for an NSNumber instance. Given that, is it ok to give NSDecimalNumbers to any code that is expecting an NSNumber? The only possible issue might be code that checks that an… >>> More

I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration.
