Question

I have two classes:

BaseClass : NSObject
AdvanceClass : BaseClass

And in AdvanceClass i have an initializer:

-(id)initWithBaseObject:(BaseClass *)bObj
{
    if(self = [super init]) {
        self = (AdvanceClass*)bObj;
    }

    return self;
}

And then when i get TRUE when i’m calling:

[myObject isKindOfClass:[BaseClass class]]

Why? I’m casting bObj to AdvanceClass object.

What i want to do here is assign all of the properties from BaseClass with properties from bObj object. How can i do that?

Answer 1

I’ve just realize that the best way is write a public method in BaseClass and call it from initializer. In that case you can only write this once, and it is simply to edit.

-(id)initWithBaseObject:(BaseClass *)bObj
{
    if(self = [super init]) {
        [self setBaseProperties:bObj];
    }

    return self;
}

And in BaseClass.m

-(void)setBaseProperties:(BaseClass*)bObj
{
    _prop1 = bObj.prop1;
    _prop2 = bObj.prop2;
    .
    .
    .
}

This is obvious solution, silly me.
