Should I keep SEL

Question

When I get a selector passed to my method, should I just save it:

-(void) setCallBack:(SEL) selectorToCall { self->mSelectorToCall = selectorToCall; } 

or should i save?

 -(void) setCallBack:(SEL) selectorToCall { self->mSelectorToCall = [selectorToCall retain]; } 

Answer 1

No, the SEL type is not an object reference, it is basically a constant pointer to a string. You can simply assign it, as in the first example.

Answer 2

No, selectors are not objects, so you cannot save them.
