expanding-collection

The iPhone mockup available here.

Requirements

  • iOS 9.0+
  • Xcode 9.0+

Installation

Just add the Source folder to your project.

or use CocoaPods with Podfile:

pod 'expanding-collection'

or Carthage users can simply add to their Cartfile:

github "Ramotion/expanding-collection"

Usage

import expanding_collection

Create CollectionViewCell

cell

1) Create UICollectionViewCell inherit from BasePageCollectionCell (recommend create cell with xib file)

2) Adding FrontView

  • add a view to YOURCELL.xib and connect it to @IBOutlet weak var frontContainerView: UIView!
  • add width, height, centerX and centerY constraints (width and height constranints must equal cellSize)

    cell

  • connect centerY constraint to @IBOutlet weak var frontConstraintY: NSLayoutConstraint!
  • add any desired uiviews to frontView

3) Adding BackView

  • repeat step 2 (connect outlets to @IBOutlet weak var backContainerView: UIView!, @IBOutlet weak var backConstraintY: NSLayoutConstraint!)

4) Cell example DemoCell

If set tag = 101 for any FrontView.subviews this view will be hidden during the transition animation

Create CollectionViewController

1) Create a UIViewController inheriting from ExpandingViewController

2) Register Cell and set Cell size:

override func viewDidLoad() {
    itemSize = CGSize(width: 214, height: 460) //IMPORTANT!!! 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

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

override func viewDidLoad() {
    itemSize = CGSize(width: 214, height: 264)
    super.viewDidLoad()

    // register cell
    let nib = UINib(nibName: "CellIdentifier", bundle: nil)
    collectionView?.registerNib(nib, forCellWithReuseIdentifier: String(DemoCollectionViewCell))
}
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    cell.cellIsOpen(!cell.isOpened)
}
if you use this delegates method:
func collectionView(collectionView: UICollectionView, willDisplayCell cell: UICollectionViewCell, forItemAtIndexPath indexPath: NSIndexPath)

func scrollViewDidEndDecelerating(scrollView: UIScrollView)
must call super method:
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

override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
    super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
    headerHeight = ***
}

OR

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    headerHeight = ***
}

3) Call the push method in YourViewController to YourTableViewController

  if cell.isOpened == true {
    let vc: YourTableViewController = // ... create view controller  
    pushToViewController(vc)
  }

4) For back transition use popTransitionAnimation()
