IOS displays different fonts and colors in Uilabel

In project development, we often encounter situations in which a uilabel uses different colors or different fonts to embody strings, and we can do this easily after iOS 6, and the official API gives us the attributedtext of the Uilabel class, Using strings of different colors and different fonts, we can use the Nsattributedtext and Nsmutableattributedtext classes to implement them.

Real code:

self.title = @"For iOS 6 & later";

NSMutableAttributedString *str = [[ NSMutableAttributedString alloc] initWithString:@ "Using NSAttributed String" ]; [str addAttribute: NSForegroundColorAttributeName value:[UIColor blueColor] range: NSMakeRange (0,5)]; [str addAttribute: NSForegroundColorAttributeName value:[UIColor redColor] range: NSMakeRange (6,12)]; [str addAttribute: NSForegroundColorAttributeName value:[UIColor greenColor] range: NSMakeRange (19,6)]; [str addAttribute: NSFontAttributeName value:[UIFont fontWithName:@ "Arial-BoldItalicMT" size:30.0] range: NSMakeRange (0, 5)]; [str addAttribute: NSFontAttributeName value:[UIFont fontWithName:@ "HelveticaNeue-Bold" size:30.0] range: NSMakeRange (6, 12)]; [str addAttribute: NSFontAttributeName value:[UIFont fontWithName:@ "Courier-BoldOblique" size:30.0] range: NSMakeRange (19, 6)]; attrLabel.attributedText = str;If you want to achieve this effect in previous versions of iOS6.0, you need to use a third-party library Tttattributedlabel, along with the import Coretext.frame framework.
