Yes, many people are saying about Rich Text in iPhone/iPad and many knows about NSAttributedString
.
But how to use NSAttributedString
? I searched for much time, no extract clues for this.
I know how to set up a NSAttributedString
, then what should I do to display a text on iPhone/iPad with rich text?
The official docs says it should be used with CoreText.Framework
, what does that mean?
Is there any simple way like this?
NSAttributedString *str;
.....
UILabel *label;
label.attributedString = str;
Starting from the iOS 6.0 you can do it like that:
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Hello. That is a test attributed string."];
[str addAttribute:NSBackgroundColorAttributeName value:[UIColor yellowColor] range:NSMakeRange(3,5)];
[str addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(10,7)];
[str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"HelveticaNeue-Bold" size:20.0] range:NSMakeRange(20, 10)];
label.attributedText = str;
