Answer 1

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationAutomatic];

Answer 2

Try changing UITableViewRowAnimationFade to UITableViewRowAnimationNone and let me know if that helps.

I just had to do the same because I'm using a static UITableView in my storyboard and it seems any animation moves the old cell out of view and replaces with the new cell. This basically removes the cell from the table because the old cell and the new cell are the same object(my assumption).

Answer 3

From UITableView documentation :

beginUpdates
Begin a series of method calls that insert, delete, or select rows and sections of the receiver.

You should not use this method unless you are inserting, deleting or selecting a row or a section.
