Maybe you want to use this

- (void)willAnimateRotationToInterfaceOrientation:UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [super willAnimateRotationToInterfaceOrientation:toInterfaceOrientation duration:duration];

    __block UIView *weakTabBar = [self.tabBarController.view.subviews objectAtIndex:1];
    weakTabBar.alpha = 0;
    [UIView animateWithDuration:duration
                          delay:0
                        options:UIViewAnimationOptionCurveEaseIn // slow at the beggining
                     animations:^{
                         weakTabBar.alpha = 1;
                     }
                     completion:^(BOOL finished) {
                         weakTabBar.alpha = 1;
                     }];
    }

}

This doesn't hide the tab bar but makes the rotate animation smoother.
