在NSTextView中使指定的文本加粗

Question

I am using a little bit of code to change the text in an NSTextView

NSString *string = @"This is a title\n\nThis is some info";
[content setString:string];

I would like to make the text "This is a title" the only text that is bold when displaying in the NSTextView and the rest normal text. Is there any way to do this? Maybe like how the StackOverflow editor works? __bold text here__

Thanks in advance!

I'm not sure if you can just apply boldness as that's usually part of another set of glyphs. But how's this work...

NSString* textUnattributed = @"This is a title\n\nThis is some info";
NSMutableAttributedString* textAttributed = [[NSMutableAttributedString alloc] initWithString:textUnattributed];
[textAttributed addAttribute:NSFontAttributeName
                       value:[UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0]
                       range:[textUnattributed rangeOfString:@"This is a title"]];
content.attributedText = textAttributed;
