value is disappearing when I scroll the table view.
Again it appears when I click on that cell.
Can anyone help me?
Thanks in Advance.
//table view in view controller created in xib
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"ListOfProductsCell";
ListOfProductsCell *cell = (ListOfProductsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
NSArray *nib =[[NSBundle mainBundle] loadNibNamed:@"ListOfProductsCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
productItemDit=[productListArry objectAtIndex:indexPath.row];
NSString *offerStr= [NSString stringWithFormat:@"%.2f",[[productItemDit objectForKey:@"offer"] floatValue]];
NSString *fullCostStr=[[currencyCodeStr stringByAppendingString:@" "] stringByAppendingString:offerStr];
NSLog(@"%@",fullCostStr);
cell.itemCostLbl.text=fullCostStr;
} else {
cell.itemStepper = (UIStepper *) [cell viewWithTag:2];
cell.itemAddedLbl =(UILabel*)[cell viewWithTag:1];
}
if (tableView == self.searchDisplayProduct.searchResultsTableView) {
searchProductItemDit=[searchProductListArry objectAtIndex:indexPath.row];
NSLog(@"searchdit:%@",searchProductItemDit);
cell.itemNameLbl.text= [searchProductItemDit objectForKey:@"name"];
self.searchDisplayProduct.searchResultsTableView.separatorColor=[UIColor colorWithRed:200.0 green:0.0 blue:0.0 alpha:1.0];
} else {
productItemDit=[productListArry objectAtIndex:indexPath.row];
NSLog(@"dit:%@",productItemDit);
cell.itemNameLbl.text=[productItemDit objectForKey:@"name"];
}
cell.itemAddedLbl.text = [[NSString alloc] initWithFormat:@"%d",itemCount];
cell.itemImg.image = [UIImage imageNamed:@"profp.jpg"];
return cell;

Solved by doing like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"ListOfProductsCell";
ListOfProductsCell *cell = (ListOfProductsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
NSArray *nib =[[NSBundle mainBundle] loadNibNamed:@"ListOfProductsCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
} else {
cell.itemStepper = (UIStepper *) [cell viewWithTag:2];
cell.itemAddedLbl =(UILabel*)[cell viewWithTag:1];
}
if (tableView == self.searchDisplayProduct.searchResultsTableView) {
cell.itemNameLbl.text= [[searchProductListArry objectAtIndex:indexPath.row] objectForKey:@"name"];
} else {
cell.itemNameLbl.text=[[productListArry objectAtIndex:indexPath.row] objectForKey:@"name"];
}
cell.itemCostLbl.text=[NSString stringWithFormat:@"%@ %.2f", currencyCodeStr , [[[productListArry objectAtIndex:indexPath.row] objectForKey:@"offer"] floatValue]];
cell.itemAddedLbl.text = [[NSString alloc] initWithFormat:@"%d",itemCount];
cell.itemImg.image = [UIImage imageNamed:@"profp.jpg"];
return cell;
}

As you haven't post much of the information this is my guess.when you scroll table view it internally calls the reloadData method . You need to use reuse Identifier to preserve the state of the cell. You can initialize the cell in cellForRowAtIndexPath like :
static NSString *cellIdentifier = @"cellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
// or cell initializing logic here for the custom cell
}
in case of custom cell add reuse identifier in the xib and use it in your cellForRowAtIndexPath method
