Table view cell reload first cell content - ios

Question

This is how my table is populated :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
CellNewsInfo *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (!cell) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cell"];
}
// Set up the cell
int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
NSString *titleArticle=[[stories objectAtIndex: storyIndex] objectForKey: #"title"];
titleArticle = [titleArticle stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if (indexPath.row==0) {
scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
scr.tag = 1;
scr.autoresizingMask=UIViewAutoresizingNone;
[cell addSubview:scr];
[self setupScrollView:scr];
UIPageControl *pgCtr = [[UIPageControl alloc] initWithFrame:CGRectMake(120, 170, 80, 36)];
[pgCtr setTag:12];
pgCtr.backgroundColor = [UIColor clearColor];
pgCtr.numberOfPages=5;
pgCtr.tintColor=[UIColor redColor];
pgCtr.pageIndicatorTintColor=[UIColor blueColor];
self.pageControl.hidden=YES;
pgCtr.currentPageIndicatorTintColor = [UIColor redColor];
pgCtr.autoresizingMask=UIViewAutoresizingNone;
[cell addSubview:pgCtr];
}
else{
cell.title.text=titleArticle;
cell.title.numberOfLines=2;
why when i scroll it , the first cell is reloading ? i just want to have that scroll view only once at the beginig .

Answer 1

The reason your scrollview is being added again is that the cells are being reused once they are deallocated.
You should look into creating your own custom cells if you are going to display multiple cells types in one tableView, or even using two different cell identifiers depending on if the row is 0.
CellNewsInfo *cell;
if (indexPath.row == 0) {
cell = [tableView dequeueReusableCellWithIdentifier:#"scrollCell" forIndexPath:indexPath];
if ([cell viewWithTag:1]) {
scr = [cell viewWithTag:1];
}
else {
scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
scr.tag = 1;
}
// continue customization here with scrollview
}
else {
cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
// continue customization here without scroll view
}
return cell;
