Animating the present and dismiss of a Share Extension with custom UI on iOS 8

Question

I'm developing a Share Extension for iOS 8 with custom UI, but it appears without animation, how can I do this? It's a regular UIViewController.

Also, it appears on fullscreen on iPad and I want it to be a modal view controller, that appears in the center of the screen and doesn't fit it, how can I do this?

Regards.

Here is the cleanest solution I found so far to animate my custom view controller in and out!

Animate IN:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    self.view.transform = CGAffineTransformMakeTranslation(0, self.view.frame.size.height);
    [UIView animateWithDuration:0.25 animations:^
    {
        self.view.transform = CGAffineTransformIdentity;
    }];
}

Dismiss:

- (void)dismiss
{
    [UIView animateWithDuration:0.20 animations:^
    {
        self.view.transform = CGAffineTransformMakeTranslation(0, self.view.frame.size.height);
    } 
    completion:^(BOOL finished) 
    {
        [self.extensionContext completeRequestReturningItems:nil completionHandler:nil];
    }];
}
