Tableview not scrolling smooth with static data

Question

I am using custom cell and headerView with static images and footerView but not scrolling as smoothly as it should scroll, it is getting stuck in middle and then scrolls........

Header

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{

UIView *headerview = [[UIView alloc]init];

if (section == 2) {
    headerview.frame  = CGRectMake(0, 30, tableView.frame.size.width, 117);
    Button = [[UIButton alloc]initWithFrame:CGRectMake(0, 18, headerview.frame.size.width, 100)];
    UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(5, 0, tableView.frame.size.width, 17)];
    label.text = @"Siddharth and hiren Like this";
    label.font = [UIFont systemFontOfSize:10];
    label.textColor = [UIColor blackColor];
    [headerview addSubview:label];


}
else
{

    headerview.frame  = CGRectMake(0, 0, tableView.frame.size.width, 100);
    Button = [[UIButton alloc]initWithFrame:headerview.frame];


}



// sheap top left and top right


UIBezierPath *maskPath;
maskPath = [UIBezierPath bezierPathWithRoundedRect:headerview.bounds
                                 byRoundingCorners:(UIRectCornerTopLeft|UIRectCornerTopRight)
                                       cornerRadii:CGSizeMake(7.0, 7.0)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
headerview.frame = headerview.bounds;
maskLayer.path = maskPath.CGPath;
headerview.layer.mask = maskLayer;


// shape for button bottom



headerview.backgroundColor = [UIColor whiteColor];

CALayer *bottomBorder = [CALayer layer];
bottomBorder.frame = CGRectMake(0.0f, 0, headerview.frame.size.width, 1);
bottomBorder.backgroundColor = [UIColor colorWithRed:217/255.0f green:217/255.0f blue:217/255.0f alpha:1].CGColor;

bottomBorder.shadowOpacity = 0.9f;
bottomBorder.shadowRadius = 0.3f;
[headerview.layer addSublayer:bottomBorder];

// Button Imageview

// imageview overlay

[Button addTarget:self action:@selector(Expand: and:) forControlEvents:UIControlEventTouchUpInside];
Button.tag = section;


if ([[AllNewsdic objectForKey:@"posts"] count] == 0) {
    [Button setTitle:[[[DownloadData objectForKey:@"posts"]objectAtIndex:section]objectForKey:@"title"] forState:UIControlStateNormal];
}
else
{
    [Button setTitle:[[[AllNewsdic objectForKey:@"posts"]objectAtIndex:section]objectForKey:@"title"] forState:UIControlStateNormal];
}

[Button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
Button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
Button.contentVerticalAlignment = UIControlContentVerticalAlignmentBottom;
Button.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
Button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;

Footer

                                       cornerRadii:CGSizeMake(7.0, 7.0)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
fotter.frame = fotter.bounds;
maskLayer.path = maskPath.CGPath;
    // maskLayer.backgroundColor = [UIColor colorWithRed:217/255.0f green:217/255.0f blue:217/255.0f alpha:1].CGColor;

// Like bUtton

// Follow Button

Cell

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
AllNewsTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"AllNews"];

cell.one.text = [one objectAtIndex:indexPath.section];
cell.two.text = [two objectAtIndex:indexPath.section];
cell.three.text = [three objectAtIndex:indexPath.section];
[cell.three sizeToFit];
return cell;}

how to set tableview scroll smooth and effective how to set interface properties tableview data is static

Answer 1

Use reusable UITableViewCell inside function viewForHeaderInSection and inside viewForFooterInSection Do not create the new UIView and buttons for each function call.
