UILabel设置多种字体、颜色

 NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Using NSAttributed String，try your best to test attributed string text"];
  [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" size:30.0] range:NSMakeRange(0, 5)];
  [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:30.0] range:NSMakeRange(6, 12)];
  [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:30.0] range:NSMakeRange(19, 6)];

  UILabel *attrLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 150, 320 - 40, 90)];
  attrLabel.attributedText = str;
  attrLabel.numberOfLines = 0;
  [self.view addSubview:attrLabel];

eg:

self.restCountLabel.text = [NSString stringWithFormat:@"剩余%@张", lmTicketModal.sysl];

            NSMutableAttributedString *noteStr = [[NSMutableAttributedString alloc]initWithString:self.restCountLabel.text];

            NSRange redRange = NSMakeRange(2,lmTicketModal.xssl.length);

            redRange.length = lmTicketModal.sysl.length;

            [noteStr addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:229/255.0 green:67/255.0 blue:80/255.0 alpha:1] range:redRange];

            

            [self.restCountLabel setAttributedText:noteStr];
