Changing value of a NSNumber

Question

Is there a way to change the value contained in an NSNumber after it is created without making it point to a different NSNumber?

NSNumber *num = [NSNumber numberW         


        

Answer 1

NSNumber is immutable. Actually, it's a subclass of NSValue, and all NSValues are immutable.

Answer 2

No, you can't change the value of NSNumber.

See, for example, this post.
