Confusing about the self and the super...

[diuming]

hi everyone,

I confuse about the self keyword in Objective-C, What kind of the method(instance method or class method) can let self to invoke? also the super keyword have same problem.

thanks all.

Did you read the description of these in the text?   self refers to the receiver of the method, and it provides a way to reference that object, for example in order to send it another message from within the method.   

super refers to the parent class of the current object, and provides a way to execute a method that you may have overridden in the current class.   I suggest you go back to the text, as a more detailed reading is required.

Cheers,

Steve

Thanks Steve,

I know them about your described self and super, But my question please refer to following :

//------------  classMethod -----------------------
+ (id)classMethod {
         id  obj = [[self alloc] init];
         return obj;
}

//----------- instanceMethod --------------------
- (id)instanceMethod {
        id obj = [self init];
        return boj;
}

The class method can only invoke super's class method whether this concept is correct?
Sorry!! My english not very well.
