reloadData so the device rotation would be more smooth

reloadData.m

-(void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator{
    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
    [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        if (size.width > size.height) {
            [self.tableView reloadData];
        }
    } completion:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        if (size.width < size.height) {
            [self.tableView reloadData];
        }
    }];
}
