Recently I received a question about working with markdown text.
Here’s a complete example of a note taking app called NoteIt from Bruno Wernimont who createded the excellent previously mentioned open source utility library BaseKit.
NoteIt accepts markdown input, and provides a very nice interface with custom keyboard keys, adding/removing notes and more optimized for both iPhone and iPad app.
Here are a couple images from the iPhone version of the app:
You can find NoteItiOS on Github here.
A great example for anyone looking to create a note taking app or looking to work with markdown.
