[Mono-osx] Using Db4Objects on MonoTouch

[Michael Probst]

Hi Joanna,

thank you for your reply!

Okay, what you are talking about is a manual binding for the CoreData Framework.
I'am currently writing on my diploma thesis (native iphone sdk vs. monotouch) .. I explained the manual binding, 
but it will be to time expensive to actually do it.

I just wanted to show an alternative (in this case "db4o") to the build in sqlite if coredata is not present..

Thanks anyway :)

You can use Core Data with Mono projects. I do that with Delphi Prism, although, you have to include the compiled .mom (Managed Object Model) file in the bundle.

You will need to create the object model in Xcode, compile it, using the momc tool, in the Terminal, and then translate the boilerplate code, that Xcode creates in Objective-C, into C# using the Monobjc bridge.

I was surprised how well the Monobjc bridge handled things and have a fully working Mono Core Data app.

It also keeps things simple as you can use Cocoa bindings to hook up the visuals directly to your business objects.
