• Use model object NoteObj
  • Each instance of a NoteObj holds one note.
  • Each note contains:
    • a title
    • a note
    • an optional array or dictionary of photos
  • Use main-view-controller– NotesController
    • Besides managing the UI - the list of Notes, the NotesController must support:
      • An array or dictionary of NoteObjs
      • Unarchiving/loading saved NoteObjs
      • deleting a Note/NoteObj
  • Use view-controller – NoteViewController– to support creating, viewing, and editing notes.
    • This controller manages the following:
      • Viewing a Note and if the note has one or more photos – displaying those photos.
      • Creating a new Note/NoteObj including with the following data:
        • The note
        • The Note Title
        • Adding one or more pictures into the note from either the camera or the camera roll.
      • Viewing and editing an existing Note/NoteObj.
      • Saving a new or edited note by archiving the model object – NoteObj into a file under your app’s documents directory in directory “MyNotes”.
