Is there any data binding mechanism available for iOS?

Question

In .NET I just do something like DataForm.Source = Object and then magic happens. Platform routes data changes from ui fileds to object properties, does validation and so on

Answer 1

Yes, there is a data binding framework that integrates well into Interface Builder and requires only minimal code overhead (if at all).

Take a look at https://github.com/mutech/aka-ios-beacon

EDIT: You can for example bind a table view to a fetched results controller simply by setting the data source binding property of the table view in interface builder to:

[ yourResultsController ] { defaultCellMapping: "YourCellId" }

And the only thing you have to do is to define a property yourResultsController in your view controller.

The wiki provides a rather complete documentation and a lot of example use cases.
