Actually, it should really be like this (I've been pedantically explicit):
- (id)init
{
self = [super init];
if(self != nil)
{
myNotes = [[NSMutableArray alloc] init];
}
return self;
}
Note that -init is NOT required to return the same object that "self"
refers to. Therefore it is always required that you re-assign self in
your overridden initializer if you need to access it, and you must
return that modified self*.

* Please note that this is the common case. If you're implementing
the singleton pattern, for example, you would override -init
differently. And there are other cases like class clusters where you
will instead be returning different objects from -init that super's
implementation returns. But these are Very Advanced Topics(TM).
