Apple's NumberInput sample code for creating an OS X input method using the Mac OS X Cocoa-based InputMethodKit framework.
In this repository I have simply sequentially committed each stage of the NumberInput_IMKit_Sample project. This allows for easily viewing the additions in each stage of the sample project.

This sample demonstrates how to write an input method using the Mac OS X v10.5 Cocoa based InputMethodKit.
This sample includes five stages. You begin with a simple do nothing version and move to a full version.

It would be great to see other projects built using the Input Method Kit framework. If you come across this sample code, feel free to post a link to your IMKit project at the GitHub issue below.
