As far as I can tell, this architectural style comes from having self-contained widgets that encapsulate very small pieces of information such as simple strings, booleans or numbers. The MVC architecture was not intended for these kinds of small widgets […]
With a widget, there is no complex model, not filtering being done by the view. The widget contains its own data, for example a string or a number. An advantage of widgets is that you can meaningfully assemble them in a tool like Interface Builder, with a more MVC-like large view, all you have in IB is a large blank space labeled ‘Custom View’. On the other hand, I’ve had very good experiences with “real” (large view) MVC in creating high performance, highly responsive user interfaces.
Probably the widest quoted pattern in UI development is Model View Controller (MVC) - it’s also the most misquoted. I’ve lost count of the times I’ve seen something described as MVC which turned out to be nothing like it. Frankly a lot of the reason for this is that parts of classic MVC don’t really make sense for rich clients these days.
