I want to place an NSAttributedString into an NSTextView, in a similar way to what the setString method does with NSString.

However, there does not appear to be any setAttributedString method for NSTextView.

I can use the insertText method, which works, but that is not quite the same thing, as it requires all existing text to be selected to have the same result, and it also calls the delegate method, textDidChange, which I definitely DON'T want.

How should I set the contents of and NSTextView to be the value of an NSAttributedString I already have?

Do this:

Code:
@interface NSTextView (MyAdditions)

- (void)insertAttributedString:(NSAttributedString *)str silent:(BOOL)silent;

@end



@implementation NSTextView (MyAdditions)

- (void)insertAttributedString:(NSAttributedString *)str silent:(BOOL)silent
{
    id delegate = [[self delegate] retain];

    if(silent)
        [self setDelegate:nil];

    [self setString:@""];
    [self insertText:str];

    if(silent)
        [self setDelegate:delegate];

    [delegate autorelease];
}

@end

I think this catagory will work for you, although I typed it straight into Chimera, so who knows.

HTH,

Thanks for the demo code. I think that should work. It's annoying that there is no such method already built in, as I would have thought it would be a fairly common operation.

I'll give your code a try. It looks a little nicer than the work around I was thinking about.

DONE!

I made some minor alterations: I didn't use the silent BOOL (and always removed the delegate temporarily); I named the method "setAttributedString"; I coded it for NSText instead of NSTextView. All of these changes make it more similar to the "setString" method that already exists (for NSStrings) in the NSText class.

It works very nicely - thank you for your help.
