Hi Albert,
You might try appending the text directly to the text storage:
NSMutableAttributedString *attstr = [[[NSMutableAttributedString alloc] initWithString:someText] autorelease];
[[textView textStorage] beginEditing];
[[textView textStorage] appendAttributedString:attstr];
[[textView textStorage] endEditing];
Cheers,
Martin
