Height of open state cell super.viewDidLoad() // register cell let nib = UINib(nibName: "NibName", bundle: nil) collectionView?.registerNib(nib, forCellWithReuseIdentifier: "CellIdentifier") } ``` 3) Add UICollectionViewDataSource methods ``` swift extension YourViewController { override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return items.count } override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCellWithReuseIdentifier("CellIdentifier"), forIndexPath: indexPath) // configure cell return cell } } ``` 4) Open Cell animation ```swift override func viewDidLoad() { itemSize = CGSize(width: 214, height: 2***) super.viewDidLoad() // register cell let nib = UINib(nibName: "CellIdentifier", bundle: nil) collectionView?.registerNib(nib, forCellWithReuseIdentifier: String(DemoCollectionViewCell)) } ``` ``` swift func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { cell.cellIsOpen(!cell.isOpened) } ``` ###### if you use this delegates method: ```Swift func collectionView(collectionView: UICollectionView, willDisplayCell cell: UICollectionViewCell, forItemAtIndexPath indexPath: NSIndexPath) func scrollViewDidEndDecelerating(scrollView: UIScrollView) ``` ###### must call super method: ```Swift func collectionView(collectionView: UICollectionView, willDisplayCell cell: UICollectionViewCell, forItemAtIndexPath indexPath: NSIndexPath) { super.collectionView(collectionView: collectionView, willDisplayCell cell: cell, forItemAtIndexPath indexPath: indexPath) // code } func scrollViewDidEndDecelerating(scrollView: UIScrollView) { super.scrollViewDidEndDecelerating(scrollView: scrollView) // code } ``` #### Transition animation 1) Create a UITableViewController inheriting from `ExpandingTableViewController` 2) Set header height default 236 ``` swift override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) { super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil) headerHeight = *** } ``` OR ``` swift required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) headerHeight = *** } ``` 3) Call the push method in YourViewController to YourTableViewController ``` swift if cell.isOpened == true { let vc: YourTableViewController = // ... create view controller pushToViewController(vc) } ``` 4) For back transition use `popTransitionAnimation()` ## — Check this library on other language: ## “ License Expanding Collection is released under the MIT license.
