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: UITa         


        

Answer 1

Swift 4:

Actually, the best way to prevent crazy animation during scrolling or expand/collapse cells is:

UIView.performWithoutAnimation {
       self.tableView.reloadRows(at: [indexPath], with: .none)
}

Answer 2

Objective-C:

[UIView setAnimationsEnabled:NO];
   [[self tableView]beginUpdates];
   [self.tableView reloadSections:[[NSIndexSet alloc] initWithIndex:1] withRowAnimation:UITableViewRowAnimationNone];
   [[self tableView]endUpdates];

But I think the following code is more useful and better.

[UIView performWithoutAnimation:^{     
                [[self tableView]beginUpdates];
                [self.tableView reloadSections:[[NSIndexSet alloc] initWithIndex:1] withRowAnimation:UITableViewRowAnimationNone];
                [[self tableView]endUpdates];
            }];
