Objective C – Custom setter with ARC?

December 1, 2023 by Tarik

The strong takes care of itself on the ivar level, so you can merely do

- (void)setMyObject:(MyObject *)anObject
{
   _myObject = anObject;
   // other stuff
}

and that’s it.

Note: if you’re doing this without automatic properties, the ivar would be

MyObject *_myObject;

and then ARC takes cares of the retains and releases for you (thankfully). __strong is the qualifier by default.
