iOS Objective-C Basics (Retired) Introduction to Objective-C Objective-C Syntax and @property

Still waiting for the right answer and explanation. Can someone help?

@interface Product : NSObject { int _qty; }

  • (int) _______;
  • (void) ________ : (int) qty;


There's not enough information at this point to know how to define the answer. Should there be underscores? No? No idea. Please help?

getter and setter methods dont use underscores in their names (they just use the name of the ivar without the _). If I had an integer instance variable named _someVar the getter method definition would be
