iOS 8 fix to support old methods of device orientation changes

iOS8ViewController.m

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
    
    //The device has already rotated, that's why this method is being called.
    UIDeviceOrientation deviceOrientation   = [[UIDevice currentDevice] orientation];
    //fixes orientation mismatch (between UIDeviceOrientation and UIInterfaceOrientation)
    UIInterfaceOrientation toOrientation;
    switch (deviceOrientation) {
        case UIDeviceOrientationUnknown:
            toOrientation = UIInterfaceOrientationUnknown;
            break;
        case UIDeviceOrientationPortraitUpsideDown:
            toOrientation = UIInterfaceOrientationPortraitUpsideDown;
            break;
        case UIDeviceOrientationLandscapeLeft:
            toOrientation = UIInterfaceOrientationLandscapeLeft;
            break;
        case UIDeviceOrientationLandscapeRight:
            toOrientation = UIInterfaceOrientationLandscapeRight;
            break;
        case UIDeviceOrientationFaceUp:
        case UIDeviceOrientationFaceDown:
        case UIDeviceOrientationPortrait:
        default:
            toOrientation = UIInterfaceOrientationPortrait;
            break;
    }
    
    UIInterfaceOrientation fromOrientation = [[UIApplication sharedApplication] statusBarOrientation];
    
    [self willRotateToInterfaceOrientation:toOrientation duration:0.0];
    [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        [self willAnimateRotationToInterfaceOrientation:toOrientation duration:[context transitionDuration]];
    } completion:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        [self didRotateFromInterfaceOrientation:fromOrientation];
    }];
