How can I tell if a UITableView contains a specific NSIndexPath?

Question

Here is the code I'm using:

if (appDelegate.currentMainIndexPath != nil /* && doesPathExistInTableView */)
{
    [tblView scrollToRowAtIndexPath:appDelegate.currentMainIndexPath atScrollPosition:UITableViewScrollPositionTop animated:NO];
    appDelegate.currentMainIndexPath = nil;
}

A Swift adaptation of Kamran Khan's answer:

extension UITableView {
  func hasRowAtIndexPath(indexPath: NSIndexPath) -> Bool {
    return indexPath.section < self.numberOfSections && indexPath.row < self.numberOfRowsInSection(indexPath.section)
  }
}

Swift 4:

extension UITableView {
    func hasRow(at indexPath: IndexPath) -> Bool {
        return indexPath.section < self.numberOfSections && indexPath.row < self.numberOfRows(inSection: indexPath.section)
    }
}
