一个信息输入tableView

1.控制sectionHeader和tableView背景色一致

2.实现如下方法，否则heightForFooter默认不是0，当人header同样

3.给输入列表加边框

-(void)tableView:(UITableView*)tableView willDisplayCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath

{

    if([cellrespondsToSelector:@selector(tintColor)]) {

        cell.backgroundColor= [UIColorwhiteColor];

        CAShapeLayer*layer = [[CAShapeLayeralloc]init];

        CGMutablePathRefpathRef =CGPathCreateMutable();

        CGRectbounds =CGRectInset(cell.bounds,0,0);

        CGFloatcornerRadius =2.0f;

        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));

        }elseif(indexPath.row==self.dataSourceArray.count-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{

            CGPathMoveToPoint(pathRef,nil,CGRectGetMinX(bounds),CGRectGetMinY(bounds));

            CGPathAddLineToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds));

            CGPathMoveToPoint(pathRef,nil,CGRectGetMaxX(bounds),CGRectGetMinY(bounds));

            CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds));

        }

        //颜色修改

        layer.strokeColor= [UIColorcolorWithRGBString:cellEdgeLineColor].CGColor;

        layer.fillColor= [UIColorwhiteColor].CGColor;

        layer.path= pathRef;

        CFRelease(pathRef);

        BOOLaddLine =NO;

        if(indexPath.row!=self.dataSourceArray.count-1) {

            addLine =YES;

        }else{

            addLine =NO;

        }

        if(addLine ==YES) {

            CALayer*lineLayer = [[CALayeralloc]init];

            CGFloatlineHeight = (2.0f/ [UIScreenmainScreen].scale);

            lineLayer.frame=CGRectMake(CGRectGetMinX(bounds), bounds.size.height-lineHeight, bounds.size.width

                                         , lineHeight);

            lineLayer.backgroundColor= [UIColorcolorWithRGBString:cellSeparatorLineColor].CGColor;

            [layeraddSublayer:lineLayer];

        }

        UIView*testView = [[UIViewalloc]initWithFrame:bounds];

        [testView.layerinsertSublayer:layeratIndex:0];

        testView.backgroundColor=UIColor.clearColor;

        cell.backgroundView= testView;

    }

}

4.准确确定tableFooterView高度

5.整体效果
