UILabel设置行间距：

            NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]initWithString:contentLabel.text];

            NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStylealloc]init];

            [paragraphStyle setLineSpacing:5];

            [attributedString addAttribute:NSParagraphStyleAttributeNamevalue:paragraphStyle range:NSMakeRange(0, contentLabel.text.length)];

            contentLabel.attributedText = attributedString;

            //调节高度

            CGSize size = CGSizeMake(width, MAXFLOAT);

            CGSize labelSize = [contentLabel sizeThatFits:size];
