Answer 1

And you can store content offset of your tableview. and can do something like,

 GPoint contentOffset = _moviesDetailTableview.contentOffset;
 [_moviesDetailTableview beginUpdates];
 [_moviesDetailTableview reloadSections:[NSIndexSet indexSetWithIndex:1]withRowAnimation:UITableViewRowAnimationNone];
 [_moviesDetailTableview endUpdates];
 [_moviesDetailTableview layoutIfNeeded];
 [_moviesDetailTableview setContentOffset:contentOffset];

Try this code,

[self.tableView reloadSection:0 withRowAnimation:UITableViewRowAnimationNone];

- (void) reloadSection:(NSInteger)section withRowAnimation:(UITableViewRowAnimation)rowAnimation {
    NSRange range = NSMakeRange(section, 1);
    NSIndexSet *sectionToReload = [NSIndexSet indexSetWithIndexesInRange:range];                                     
    [self reloadSections:sectionToReload withRowAnimation:rowAnimation];
}
