So, that was why it was not working. I was trying to execute a script
that looked like:
[textField replaceCharactersInRange:withRTF:fileContents]
However, the script you gave me does not seem to work. Here is what I
have total:
- (void)windowControllerDidLoadNib:(NSWindowController *) aController;
{
[super windowControllerDidLoadNib:aController];
if (fileContents)
{
// this line would be different in your implementation...
// say, replaceCharactersInRange:withRTF:
[textView replaceCharactersInRange:NSMakeRange(0,0)
withRTF:fileContents];
[fileContents release];
fileContents = nil;
}
}
But it gives me this error when trying to open an RTF file:
2002-02-23 11:51:14.249 PowerText[4025] *** Assertion failure in
-[Document loadDataRepresentation:ofType:], Document.m:31
2002-02-23 11:51:14.253 PowerText[4025] Unknown type
Can you figure our what is going wrong?
Sorry about these stupid questions.
