I declare it in the interface, and in implimentation I alloc and init.
so it's like
NSMutableArray *myarray;
myArray = [[NSMutableArray alloc] init]
If I do the second line in init method of class, it doesnt stick around.
but if I do it in awakefromnib it's there.

The best place to set a class variable is in the + (void)initialize;
method.
However, if the variable is only needed in a single method its better
to declare it as a static variable inside the method, that way you
avoid polluting the global namespace.
That said I can't see why the method you create it in would matter, so
long as the object you are pointing it too has a retain count of 1
(and is not autoreleased) and you don't release it: it should stick
around for the duration of your app's execution.
How are you declaring the class variable? How are you assigning it?
