iOS自定义文字高度添加行间距

在创建cell时- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

NSString * sttr = [NSString stringWithFormat:@"%@%@",arrayload[indexPath.row],arraymodeltext[indexPath.row]];
                
                NSMutableAttributedString * strAttebute = [[NSMutableAttributedString alloc] initWithString:sttr ];
                
                //设置行间距
                NSMutableParagraphStyle * paragraphStlyle = [[NSMutableParagraphStyle alloc] init];
                [paragraphStlyle setLineSpacing:IPHONEHIGHT(10)];
                [strAttebute addAttribute:NSParagraphStyleAttributeName value:paragraphStlyle range:NSMakeRange(0, sttr.length)];
                
                [strAttebute addAttribute:NSForegroundColorAttributeName value:qianse range:NSMakeRange(0, [arrayload[indexPath.row] length])];
                
                full.labelText.attributedText = strAttebute;
                
                CGSize contentSize = [sttr  boundingRectWithSize:CGSizeMake(ScreenWidth-IPHONEHIGHT(56),MAXFLOAT ) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:IPHONEWIDTH(30)]} context:NULL].size;
                
                full.labelText.size =CGSizeMake(contentSize.width, contentSize.height);
                
                height0 = contentSize.height;
                
              
                return full;
