//获取要展示的内容
NSString * string = [NSString stringWithFormat:@"%@\n\n %@\n\n%@",model.authorName,model.description,model.seriesTitle];
        NSMutableAttributedString *AttributedStr = [[NSMutableAttributedString alloc]initWithString:string];
      //设置行间距
        NSMutableParagraphStyle * style = [NSMutableParagraphStyle new];
        style.lineSpacing = 10.0f;
        style.paragraphSpacing = 20.f;
//设置内容到结尾的样式
        [AttributedStr addAttribute:NSParagraphStyleAttributeName value:style range:NSMakeRange(model.description.length, model.seriesTitle.length)];
        [AttributedStr addAttribute:NSFontAttributeName
         
                              value:[UIFont systemFontOfSize:17.0]
         
                              range:NSMakeRange(0, model.authorName.length)];
        NSLog(@"%lu",(unsigned long)model.authorName.length+model.description.length);
        [AttributedStr addAttribute:NSForegroundColorAttributeName
         
                              value:[UIColor grayColor]
         
                              range:NSMakeRange(model.authorName.length, model.description.length)];
        _titleLabel.attributedText = AttributedStr;
注：多行情况下要设置numberOfLines=0 不然是看不到内容的。
