In iOS 7, using UIModalPresentationCurrentContext for an animated modal presentation doesn't animate

In iOS 8, when presenting a modal (lets say with a transparent background), we need to set the segue (or the modal) to use the presentation style of UIModalPresentationOverCurrentContext. This is working as expected.

To accomplish the same thing for iOS 7, you instead, need to set the presenting view controller to have a modal presentation style of UIModalPresentationCurrentContext. Here's where I'm having an issue. I present the modal with animation, but it doesn't animate. After it is presented, everything works fine, even animating the dismissal. Further, if I change the presentation style to UIModalPresentationFullScreen, it animates correctly.

I've searched around and read other posts, but I can't find the cause of this or a solution.

  ViewController *vcObj = [[ViewController alloc] initWithNibName:NSStringFromClass([ViewController class]) bundle:nil];
    UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:vcObj];

    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {

        navCon.providesPresentationContextTransitionStyle = YES;
        navCon.definesPresentationContext = YES;
        navCon.modalPresentationStyle = UIModalPresentationOverCurrentContext;

        [self presentViewController:navCon animated:NO completion:nil];
    }
    else {

        AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
        [self presentViewController:navCon animated:NO completion:^{
            [navCon dismissViewControllerAnimated:NO completion:^{
                appDelegate.window.rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
                [self presentViewController:navCon animated:NO completion:nil];
                appDelegate.window.rootViewController.modalPresentationStyle = UIModalPresentationFullScreen;

            }];
        }];
    }
