NSAttributedString with strikethrough

Question

I'm trying to create an attributed string with a strikethrough, however, this simple task seems to be harder to figure out than I anticipated. Here is what I have currently (which is not working). Thanks for the help!

NSAttributedString *theTitle = [[[NSAttributedString alloc] initWithString:@"strikethrough text" attributes:[NSDictionary dictionaryWithObjectsAndKeys:[NSColor whiteColor], NSForegroundColorAttributeName, NSUnderlinePatternSolid, NSStrikethroughStyleAttributeName, nil]] autorelease];

Answer 1

First, the value for NSStrikethroughStyleAttributeName must be an NSNumber, not a simple integer. Second, I think you have to include NSUnderlineStyleSingle:

...:[NSDictionary dictionaryWithObjectsAndKeys:
      ..., 
      [NSNumber numberWithInteger:NSUnderlinePatternSolid | NSUnderlineStyleSingle], 
      NSStrikethroughStyleAttributeName, 
      nil]...

Answer 2

You can also simply use:

NSAttributedString *theAttributedString;
theAttributedString = [[NSAttributedString alloc] initWithString:theString 
            attributes:@{NSStrikethroughStyleAttributeName:
            [NSNumber numberWithInteger:NSUnderlineStyleSingle]}];

Update :

Swift 2.0 version

let theAttributedString = NSAttributedString(string: theString, attributes: [NSStrikethroughColorAttributeName: NSUnderlineStyle.StyleSingle])
