  Adding a little more detail: To stylize your content, you create a 'mask' by specifying the character ranges that you want to change, and then applying attributes to the string Snippet to take a gray-colored string "Hello World", and then make "World" show as a black color (from memory): NSString *theEntireLineOfText = @"Hello World"; UIColor *boldColor = [UIColor blackColor]; UIFont *myFont = [UIFont fontWithName:@"Helvetica" size:12.0]; UIColor *baseColor = [UIColor grayColor]; NSDictionary *subAttrs = [NSDictionary dictionaryWithObjectsAndKeys: myFont, NSFontAttributeName, boldColor,NSForegroundColorAttributeName, nil]; NSMutableAttributedString *mainText = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@",theEntireLineOfText] attributes:@{NSFontAttributeName:myFont,NSForegroundColorAttributeName:baseColor}]; // Make the word "World" black" NSRange range = NSMakeRange(0,[@"World" length]); [mainText setAttributes:subAttrs range:range];
