Pinboard is a simple document centric application written using Xamarin.Mac. It allows you to create a document containing a collection of named, colored overlapping rectangles. This is useful for screen layout and content placement. It is used to create the screen layouts for the iOS app Jamoki Spider Solitaire for example.
The app serves as a very full featured example of how to write model/view/controller (MVC) applications using Xamarin.Mac. It is a great starting place for a real document centric application because it includes most of the things you are likely to need in such an app, including undo and multi-selection.
Specifically, it shows how to use the follow classes and concepts in Cocoa on iOS:
- NSScrollView (for scrolling and magification)
- KVC/KVO and binding
- NSWindowController
- NSDrawer
- NSArrayController
- NSObjectController
- NSUndoManager
- NSToolbar
- NSMenu/NSMenuItem
- Custom NSViews
- Quartz graphics
- Advanced XIB files
The app also makes use of Mono libraries for loading and saving XML files.
If you have the Sketch application, you can see how easy it is to create great looking resources for your OSX applications using it. The folder RawResources contains the origin .sketch artwork that is used to generate all the .png files in the Resources directory.
As it stands now, the codebase makes a great starting point for a simple vector drawing program, or other graphics centric application.
