Properties and accessors in Objective-C

Question

Does the following code call an accessor \"set\" function or does it modify the pointer myMember directly?

aClass.h

@interface MyClass :         


        

Answer 1

Without the self. notation, the instance variable is modified directly. With it, the property setter is called (and since you made it a retain property, the new pointer that it's being set to will be sent a retain message).

See Apple's documentation on declaring and accessing properties.
