          NSLog(@" child post");
         ChildViewController *objChildViewController=[[ChildViewController              alloc]initWithNibName:@"ChildViewController" bundle:nil];
         [cell.child setHidden:NO];
         [objChildViewController getchild:posts_id:buttontag1 :uid:frame2];

OK you want to increase the height on button click not on selecting the cell.. — BalaChandra, Jan 28 '14 at 05:30
there is a button. After clicking on that button the height of cell should increase. — Saba Sayed, Jan 28 '14 at 05:32
Is the button on the cell ? Is the button's tag the cell's row index ? — KudoCC, Jan 28 '14 at 05:35
On button click, reload the table and in heightForRowAtIndexpath delegate method, return your new height and in cellForItemAtIndex add you view to the cell this time. — dispatchMain, Jan 28 '14 at 05:36

hope this helps.

@interface ViewController ()
{
int currentselection;
int cellno;
UITableView *table;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// do things with your cell here

// set selection
cellno = indexPath.row;


}
-(void)buttonpressed
{
currentselection = cellno;
[table beginUpdates];
[table endUpdates];

}
-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
int rowHeight;
if ([indexPath row] == currentselection) {
    rowHeight = 200;
} else rowHeight = 100;
return rowHeight;
}
