title: How to Auto Sliding Images with collectionView
body: <p>I want to create a slideshow with <code>UICollectionView</code>. Now I've created a collection view and also a custom cell. I am showing all the images, but not auto scrolling. So I want, when the view controller is loaded, all the cell of collection view should scroll automatically, even when sliding button pressed. But I searched all the documents but haven't found. So please give any idea or give me any tutorial link also. </p>
