I know I can use the IMP to call directly a methods code, eg:
SEL s = @selector(myMethod);
IMP i = [myObject methodForSelector:s];
i(anObject,anSelector);
I understand that the function call needs an object it reference to (eg. for
a link to the instance variables of an object).
But why does the function call need a selector? I would think that the IMP
IS the reference without the need of a Selector again. Even if I put nil
into the place of "anSelector" it seems to me to work without any problems.
Can anybody explain the reason for that parameter to me?
Thank You
Roman
