Another solution (which can also be used to check if a row is fully visible) would be to check if the frame for the row is inside the visible rect of the tableview.

In the following code, ip represents the NSIndexPath:

CGRect cellFrame = [tableView rectForRowAtIndexPath:ip];
if (cellFrame.origin.ytableView.contentOffset.y+tableView.frame.size.height-tableView.contentInset.top-tableView.contentInset.bottom){ // the row is below visible rect
  [tableView scrollToRowAtIndexPath:ip atScrollPosition:UITableViewScrollPositionBottom animated:NO];
}

Also using cellForRowAtIndexPath: should work, since it returns a nil object if the row is not visible:

if([tableView cellForRowAtIndexPath:ip]==nil){
  // row is not visible
}
