Can anyone suggest How to do this.
Thanks in Advance.

Set,

CGPoint _contentOffset = CGPointMake(tableView.contentOffset.x, aNegativeYValue);
tableView.contentOffset = _contentOffset;

If you want it animated, use,

CGPoint _contentOffset = CGPointMake(tableView.contentOffset.x, aNegativeYValue);
[tableView setContentOffset:_contentOffset animated:YES];

You can also use table view's scrollToRowAtIndexPath:atScrollPosition:animated: method.

The simplest way is to embed your tableView (and your other views, since you apparently have more than one view on screen) in a UIScrollView.

Then when you present the popup window on screen, calculate an offset to scroll to by getting your popup window's size, then slide up the tableView using [scrollView setContentOffset:MyOffset animated:YES].
