Hey *Nic*,
Thanks man. Yeah - I'm not talking about anything as radical as all the
way into MVVM pattern (and corresponding data-binding requirements).
I'm merely looking at where you have a Model (or hierarchy of models) that
contain domain logic. This model may be passed out across many different
view/controllers, and if for some reason one part of the model changes (eg.
though a user interaction, or some data update) signaling to all concerned
controllers via an event. Or more specifically - a "this *Property* just
changed" event.
Most of the samples I've seen so far around MonoTouch have the models being
basically nothing more than simple data objects. Where as I like to
encapsulate the generic - non-UI specific, domain logic in these objects.
I'm assuming the samples are like this for simplicity sake. But want to
check that assumption, and make sure it's not some kind of "way of doing
things in iOS". I wouldn't expect that to be the case.
Also, C# events feel to me like a far more elegant way of expressing the
observer pattern. Doing a sanity check here. Is this crazy to be thinking
this way. Am I going against the grain.
