Use CoreData in MonoTouch?

问题:

I have seen that there are so wonderful ways in Xcode to design your CoreData models - is there a way to make use of this and CoreData in general in MonoTouch 5? Any tutorials or examples?

Maybe is not the direct answer to your question but might be what you are looking for:

• Sqlite-net is an open source, minimal library to allow .NET and Mono applications to store data in SQLite 3 databases. <- the one you are using but for future reference

• Vici CoolStorage is a fully typed Object Relational Mapping library for .NET 3.5, Windows Phone, MonoTouch and Mono for Android

• Catnap is a basic lightweight ORM for .NET. It uses the ADO.NET API. The project includes an adapter for Sqlite, and it is tested with System.Data.Sqlite and Mono.Data.Sqlite.

• MonoTouch.SQLite An abstract UITableViewController to make displaying data from an SQLite table simpler.

• Entify is entity framework for desktop and mobile applications. It aims to be stable and easy-to-use library that is effortless to deploy with any application. It has visual designer which allows developer to define application data model easily and quickly.

  • Just a side note on entify, it has not been updated since Apr 11, 2010 so idk if it still works

The only thing I could find about MonoTouch and CoreData was this blog post.

Hope this helps.

Here is the documentation for CoreData in Mono.

This blog post is almost two years old, but the only example I could find of using CoreData in Mono.

Most relevant to your question, however, this bug/request is for integrating Xcode's tools into Mono. It doesn't seem to even be under development yet.

Edit: You can also use /Applications/Xcode.app/Contents/Developer/usr/bin/momc <source xcdatamodel> <absolute path to target> to generate the .momd. I'm still working on getting it integrated better - see this question.
