iOS UILabel设置行间距和字间距并计算高度

 NSString *labelText = goods.goods_2;

        NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:labelText];

        NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

        [paragraphStyle setLineSpacing:5];

        [attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [labelText length])];

        self.goodsRemark.attributedText = attributedString;

        self.goodsRemark.lineBreakMode = NSLineBreakByTruncatingTail;

        [self.goodsRemark sizeToFit];

        self.goodsRemark.frame = CGRectMake(left, self.heightCell+19*SizeScale, WIDTH-left*2, [self getSize:self.goodsRemark]);

//计算高度

- (CGFloat)getSize:(UILabel *)content

{

    CGSize size = [content.text boundingRectWithSize:CGSizeMake(WIDTH-left*2, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{content.font:NSFontAttributeName} context:nil].size;

    CGSize labelSize = [content sizeThatFits:size];

    return labelSize.height;
