    //时间
            _timeLabel = [[UILabel alloc] init];
            [self.contentView addSubview:_timeLabel];
            _timeLabel.font = [UIFont systemFontOfSize:12];
            _timeLabel.textAlignment = NSTextAlignmentRight;
            _timeLabel.textColor = UIColorFromRGB(0x999999);
            [_timeLabel mas_makeConstraints:^(MASConstraintMaker *make) {
                make.right.equalTo(weakSelf.contentView.mas_right).offset(-11);
                make.top.equalTo(weakSelf.topClearView.mas_top).offset(16);
            }];
            
            //标题
            _titleLabel = [[UILabel alloc] init];
            [self.contentView addSubview:_titleLabel];
            _titleLabel.numberOfLines = 1;
            _titleLabel.font = [UIFont systemFontOfSize:16];
            _titleLabel.textAlignment = NSTextAlignmentLeft;
            _titleLabel.textColor = UIColorFromRGB(0x111111);
            _titleLabel.lineBreakMode = NSLineBreakByTruncatingTail;
            [_titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {
