I sure hope not! The documentation for the method states:
"The init method defined in the NSObject class does no initialization;
it simply returns self."
Making it do anything else would be a serious breach of the API
contract.
However I strongly advocate calling it anyway, as it makes your code
more robust if you change the superclass later on to something that
really does do something in init.
Exactly
I didn't say *who* might change it!
It is quite common to....
- create a subclass of NSObject
- create another subclass of NSObject
- realize that A and B have a bit in common...
- ... and create a common superclass from which A and B can share
functionality
By following the rules with consistency throughout your code, you
minimize the pain of maintenance and transmogrification over time.
