}
[[self tableView] beginUpdates];
[[self tableView] insertRowsAtIndexPaths:(NSArray *)ar withRowAnimation:UITableViewRowAnimationNone];
[[self tableView] endUpdates];
[self.tableView reloadData];
}

Answer 1

Here Fazil.... basic code for any tableview and the row addition
- (void)insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation;
UITableView *tableview = [[UITableView alloc]initWithFrame:CGRectMake(160, 280, 150, 150) style:UITableViewStylePlain];
tableview.delegate = self;
tableview.dataSource = self;
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [array count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier ];
}
cell.textLabel.text= [array objectAtIndex:indexPath.row];
cell.imageView.image = [UIImage imageNamed:[imagearray objectAtIndex:indexPath.row]];
cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_normal.png"]];
cell.textLabel.textColor = [UIColor blackColor];
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
cell.textLabel.font = [UIFont fontWithName:#"Helvetica" size:17.0];
return cell;
}
#pragma mark UItableView delegate
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
check = indexPath.row;
UITableViewCell* theCell = [tableView cellForRowAtIndexPath:indexPath];
theCell.contentView.backgroundColor=[UIColor clearColor];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (void)moveRowAtIndexPath:(NSIndexPath *)indexPath toIndexPath:(NSIndexPath *)newIndexPath
{
[tableview moveRowAtIndexPath:indexPath toIndexPath:[NSIndexPath indexPathForRow:[array count] - 1 inSection:1]];
}
- (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath
{
if (sourceIndexPath.section != proposedDestinationIndexPath.section) {
NSInteger row = 0;
if (sourceIndexPath.section < proposedDestinationIndexPath.section) {
row = [tableView numberOfRowsInSection:sourceIndexPath.section] - 1;
}
return [NSIndexPath indexPathForRow:row inSection:sourceIndexPath.section];
}
return proposedDestinationIndexPath;
}
