  NSMutableAttributedString *attriOneStr = [[NSMutableAttributedString alloc]initWithString:@"来呀,快活呀,反正有大把时光" attributes:arrDic];
  self.oneLabel.attributedText = attriOneStr;

  // 简单的图文混排
  NSMutableAttributedString *arrTwoStr = [[NSMutableAttributedString alloc]init];
  NSMutableAttributedString *TwoChildStr = [[NSMutableAttributedString alloc]initWithString:@"你好啊"];
  [arrTwoStr appendAttributedString:TwoChildStr];

  NSTextAttachment *attachMent = [[NSTextAttachment alloc]init];
  attachMent.image = [UIImage imageNamed:@"2"];

  [arrTwoStr appendAttributedString:picStr];

  NSAttributedString *TwooStr = [[NSAttributedString alloc]initWithString:@"我是小菜鸟"];
  [arrTwoStr appendAttributedString:TwooStr];
