I want to initialize an instance of one of the subclasses of a superclass depending on the arguments to init:
[[Vehicle alloc] initWithItinerary: shortWay]; // returns a bicycle
[[Vehicle alloc] initWithItinerary: longWay]; // returns a car
I can't find examples of code like this. I wonder if this is not idiomatic in Objective C, or I simply am not looking in the right places.
