title: Apple like shaking icons in UICollectionView in iOS?
body: <p>I want to develop an app in which the items should be displayed as the <code>UICollectionView</code>. When user tap &amp; hold the items all the items should start shaking like the Apple home screen on which icons start to shake when we want to delete an app. So please tell me how can I implement this feature. Is there any library can use?</p>
