1、如果有sectionHeaderView情况，第一行不设置圆角，在添加sectionHeaderView的时候设置圆角即可。

2、如果没有有seciontHeaderView情况，那么可以直接设置

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
        if ([cell respondsToSelector:@selector(tintColor)]) {
            CGFloat cornerRadius = 10.f;
            cell.backgroundColor = UIColor.clearColor;
            CAShapeLayer *layer = [[CAShapeLayer alloc] init];
            CGMutablePathRef pathRef = CGPathCreateMutable();
            CGRect bounds = CGRectInset(cell.bounds, 10, 0);
            BOOL addLine = NO;
            if (indexPath.row == 0 && indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
                CGPathAddRoundedRect(pathRef, nil, bounds, cornerRadius, cornerRadius);
            } else if (indexPath.row == 0) {
    
                CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds));
                CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds), CGRectGetMidX(bounds), CGRectGetMinY(bounds), cornerRadius);
                CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
                CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds));
                addLine = YES;
                
            } else if (indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
                CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds));
                CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds), CGRectGetMidX(bounds), CGRectGetMaxY(bounds), cornerRadius);
                CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
                CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds));
            } else {
                CGPathAddRect(pathRef, nil, bounds);
                addLine = YES;
            }
            layer.path = pathRef;
            CFRelease(pathRef);
            //颜色修改
            layer.fillColor = white_Color.CGColor;
            layer.strokeColor=[UIColor whiteColor].CGColor;
            // 阴影颜色
            layer.shadowColor = black_Color.CGColor;
            // 阴影偏移，默认(0, -3)
            layer.shadowOffset = CGSizeMake(0,-3);
            // 阴影透明度，默认0
            layer.shadowOpacity = 0;
            if (addLine == YES) {
                //设置分割线
                CALayer *lineLayer = [[CALayer alloc] init];
                CGFloat lineHeight = (1.f / [UIScreen mainScreen].scale);
                lineLayer.frame = CGRectMake(CGRectGetMinX(bounds)+10, bounds.size.height-lineHeight, bounds.size.width-10, lineHeight);
                lineLayer.backgroundColor = tableView.separatorColor.CGColor;
                [layer addSublayer:lineLayer];
            }
            //设置背景view
            UIView *clickBgView = [[UIView alloc] initWithFrame:bounds];
            [clickBgView.layer insertSublayer:layer atIndex:0];
            clickBgView.backgroundColor = UIColor.clearColor;
            cell.backgroundView = clickBgView;
        }
    }
