Objective C categories -

i have 2 classes , lets classa , classb , classb subclass of classa .

and adding category classa ,

@interface classa (datahandling) -(void)adddata; @end

then sublcass add category ,

@interface classb (datahandling) -(void)adddataglobally; @end

will treated single category on multiple categories , run in conflicts, though method names different ?

those 2 different categories on 2 different classes.

no conflicts take place, it's considered best practice prefix category methods unique identifier, like

-(void)my_adddataglobally;
