getting text from a .rtf file :
this is what i’ve got so far…
gameInfoTextView.text = [UITextView textNamed:@"mw3InfoText.rtf"];
or
NSString *myText = [NSString stringWithContentsOfFile:@"mw3InfoText.rtf" encoding:NSUTF8StringEncoding error:nil];
gameInfoTextView.text = myText;
You need to read the file first.
Here is a link explaining how to do it.
