ios - Reload tableview section without scroll or animation

Question

I am reloading a tableView section using this code -

self.tableView.beginUpdates()
self.tableView.reloadSections(NSIndexSet(index: 1), withRowAnimation: UITableViewRowAnimation.None)
self.tableView.endUpdates()

Still the rows replacement is animated and the table view scrolls to the top.

How can I make sure that no animation will be applied to the section reload + prevent the table view from scrolling.

Answer 1

To prevent scrolling and animation, do this:

UIView.performWithoutAnimation { 
    let loc = tableView.contentOffset
    tableView.reloadRows(at: [indexPath], with: .none)
    tableView.contentOffset = loc
}
