Question

I have a class that implements a protocol . In MyProtocol, I have two properties:

@protocol MyProtocol <NSObject>
    @property(nonatomic, retain) NSObject *stuff;
    @property(nonatomic, retain) NSString *stringStuff;
@end

My class implements the protocol as shown

Header .h

@interface MyClass : UIViewController <MyProtocol>
...

Implementation.m

@implementation MyClass
    @synthesize stuff;
    @synthesize stringStuff;
...

I have a class that inherits from MyClass…

@interface MySubClass : MyClass

When I try to access stuff and stringStuff in MySubClass, I get an error saying that MySubClass does not have a member named ‘stringStuff.’

How can I get the child classes to be able to access these members of the parent class?

Answer 1

You will need to use property access in the subclass, were you trying to access the ivars directly?

Edit: Just realised I didn’t answer your original question. Yes, if a superclass implements a protocol then the subclass will too.
