Question

I just simply release objects as such:

[myObj release];

I have seen others add:

[myObj release]; myObj = nil;

Is the latter more advantageous because now there will never be a reference to that pointer?

Answer 1

It is just to make sure that other successive messages that might be send to myObj don’t throw an exceptions. Message send to nil are possible in Objective-C.

Otherwise, myObj still points to the memory address where it has been and accessing it might result in a BAD_ACCESS error.
