Hi list...
I4m including a lot of code in this mail so i4ll make this as short as
possible! I4m trying to learn Cocoa by writing a text-editor! Well today
i try4ed implementing saving and opening RTF documents but i got into
some problems:
When the app saves or opens a document it shows all of the RTF tags!
Example:
If i make a new document and type the word "Apple" and save, this is
what the text in the textview is turned into:
{\rtf1\mac\ansicpg10000\cocoartf100
{\fonttbl\f0\fswiss\fcharset77 Helvetica;}
{\colortbl;\red255\green255\blue255;\red0\green0\blue0;}
\pard\tx560\tx1120\tx1680\tx2240\tx2800\tx3360\tx3920\tx4480\tx5040\tx5600\
tx6160\tx6720
\f0\fs24 \cf2 Apple}
Not so fancy huh?
As i understand it ive either:
Ive forgotten to implement some important block of code
Implemented to much code
Please help me cause this is the only thing i need before my app can go
into beta!
The document section of the app source code:
ALL SUGGESTIONS ARE WELCOME BUT PLEASE INCLUDE SOME CODE CAUSE I`M STILL
A NEWBIE!
#import "MyDocument.h"
