@funkyboy

I’d suggest a different method:

set up a designated initializer

- init (parameter p1, parameter p2)

and have your initialisers call this initialiser with default values for the parameters not passed in.

I’m not sure what you mean. Do you mean three initializer methods, one that takes no parameter, one that takes one data type (say NSSinteger) and another that takes a different data type, say NSDate?

In that case, you could still use the code above, passing in nil for any parameters that you don’t have. For instance, if you want to initialize a date but not a string, pass in nil for the string. And vice-versa, if you want to initialize a string but not the date, pass in nil for the date.

Hope that helps.

Hi,

very interesting post! And also interesting web site initiative.
One question (I struggled with):

What if my domain is modeled in a way that there is:

- init (no parameters)
- init (a parameter p1)
- init (a parameter p2)

is it p1 to call p2 or viceversa?

Thanks,
