Question

- (id) init
{
     [super init];
     //initialitation of the class
     return self;
}

I know that when I am inheriting from another class I am suppose to call super.init

Does this apply to “inheriting from NSObject” ?

Answer 1

Yes, usually you have something like:

- (id) init
{
    if (self = [super init]) {
        // instantiation code
    }

    return self;
}
