Question

In my app I am getting the data from the web-service and I have to display it in UITableView.
But the condition here is I have to display only 10 records initially,then once the user scroll down I have to load more records.I tried searching it but didn’t get any useful answer.
I agree that I will use –

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

to display the value,but how will I fetch only 10 records from the service and then other record based on scroll.
Please provide some pointers or sample code.

Thanks

In case if some one need it,i was able to solve my problem this way.
First thing is you need the server configuration in such a way so that it should return 10 data at a time based on the row which is visible in TableView.
This is the tableView delegate which get called and returns the visible cells in tableView

 -(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
    {
        int lastRow=[nameArray count]-1;
        if(([indexPath row] == lastRow)&&(lastRow<[categoryArray count]))  
        {

            if(tableView==m_pDetailsTableView)    {
                savedScrollPosition=lastRow;
                startCellValue=[NSString stringWithFormat:@"%d",0];
                endCellValue=[NSString stringWithFormat:@"%d",[nameArray count]+10];
                [self connectToServer]; //Method to request to server to get more data
            }
        }
    }

savedscrollPosition variable stores the variable as a point where you want to scroll the table view after load of data.
