For that you can set as a button.If you click that button in tableview,you can get more data or else you can get data step by step like ten by ten data.

Create Custom Cell and Set the Button in Custom Cell also give name as btnLoadMore

In header file

@interface myViewController : UIViewController {
    int loadMoreTableInt;
    int paginationInt; 
}

In .m file

 - (void)viewDidLoad {
      [super viewDidLoad];
      loadMoreTableInt = 0;
      paginationInt = 1;    
 }


 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

      customCell *cell=(customCell*)[tableView dequeueReusableCellWithIdentifier:@"Reuse"];

      NSArray *nib=[[NSBundle mainBundle] loadNibNamed:@"customCell" owner:self options:nil];

      if(cell == nil) {

         cell=[nib objectAtIndex:0];

      }

     if(loadMoreTableInt-1> indexPath.row) {

        cell.labelName.text = [NSString stringWithFormat:@"%@",[modelRoot.arrayName objectAtIndex:indexPath.row]];


     } else {

        if(cell == nil) {
           cell=[nib objectAtIndex:1];
        }

        [cell.btnLoadMore setTitle:[NSString stringWithFormat:@"Load More "] forState:UIControlStateNormal];

        cell.btnLoadMore.tag=indexPath.row;

        cell.accessoryType=UITableViewCellAccessoryNone;

        [cell.btnSeeMorebtnLoadMore addTarget:self action:@selector(loadmoreButtonAction:) forControlEvents:UIControlEventTouchUpInside];
                    cell.selectionStyle=UITableViewCellSelectionStyleNone;

  }

In loadmoreButtonAction give the code like this

 -(void)loadmoreButtonAction:(id)sender {

     @try {
         UIButton *btn=(id)sender;

         paginationInt=paginationInt+1;
         [tableview reloadData];

         CGPoint point;
         point.x=40;
         point.y=btn.tag*53;

         NSIndexPath *path = [tableview indexPathForRowAtPoint:point];
         [tableview scrollToRowAtIndexPath:path atScrollPosition:UITableViewScrollPositionTop animated:NO];

        }@catch (NSException *exception) {

      }
 }

Ok so you're gonna have to hack this all together. This is the usual approach to get a "Load more data" cell on your uitableview

Methods Needed

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
   return dataRows+1;
}



- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

    //after setting tableviewcell

    if(indexPath.row==dataRows){

    cell.textLabel.text=@"Load More Rows";
    }
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

   if(indexPath.row==dataRows){
      //there you can write code to get next rows
   }
}

Ok this is where the hacking will have to begin. Look at this CODE.

The method that seems to be most important is

- (void)reloadTableView:(int)startingRow
