I was surprised to learn that a hierarchy of NSDictionary objects can
be queried with valueForKeyPath:
NSDictionary *dict0 = [NSDictionary dictionaryWithObjectsAndKeys:@"got
me!", @"2", nil];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:dict0,
@"1", nil];
NSLog([dict valueForKeyPath:@"1.2"]);
This is powerful functionality.
Am I blind (again), or is this fact omitted from the docs? Or is it
implicit from the nature of KVC?
Googling turns up references to the same functionality in WebObjects.
