Tumblr- and Tweetbot-like view on top of UIActivityViewController, with appearance animation (put it on a subclass of UIActivityViewController)

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

	CGFloat distance = 10.0;
	[self.transitionCoordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context) {
	[UIView performWithoutAnimation:^{
	self.effectView.frame = CGRectMake(0, self.view.frame.size.height - self.effectView.frame.size.height - distance, self.view.frame.size.width, self.effectView.frame.size.height);
	}];
	self.effectView.frame = CGRectMake(0, -self.effectView.frame.size.height - distance), self.view.frame.size.width, self.effectView.frame.size.height);
