:star: What does it do ?

ToastCollectionView is a Swift UICollectionView that pushes and displays views when scrolling, reminding of a toast popping out of a toaster 🍞

It is useful is you wish to display information about the content of your cells

Example Toast Collection View

📲 Example

To run the example project, clone the repo, and run pod install from the Example directory first.

📋 Requirements

ToastCollectionView requires iOS 9 and Swift 4

📦 Installation

ToastCollectionView is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'ToastCollectionView'

😏 Usage

1. Create yourself a ‘Toast’ view that your cells will display upon scrolling

Create a class that inherits from the UIView class, with the shape and design you want…

class MyToastView: UIView {
    // Your code here

2. Create your ToastCollectionView replacing your current UICollectionView

  1. Instantiate a ToastCollectionView

  2. Implement the datasource and delegate

Set the Toast view offsets :

  • maxPositionForComponent is how high you want your toast to go when scrolling

  • offsetToComponent is the offset between the CollectionView and each toast for triggering movements


class ViewController: UIViewController {

    var collectionView: ToastCollectionView?

    override func viewDidLoad() {

        // Instanciate the CollectionView
        let collectionViewLayout = UICollectionViewLayout()
        self.collectionView = ToastCollectionView(frame: CGRect, collectionViewLayout: collectionViewLayout)

        // Set the offsets
        self.collectionView.maxPositionForComponent = 75.0
        self.collectionView.offsetToComponent = 30.0

        // Set the delegates
        self.collectionView.delegate = self
        self.collectionView.dataSource = self

3. Create a UICollectionviewCell that inherits from ToastCollectionViewCell

Override the toastViewForCell() method, and return your Toast view

override func toastViewForCell() -> UIView? {
    // Return the Toast view with the size you want
    return MyToastView(frame: CGRect(x: 0, y: 0, width: 150, height: 50))

If you wish to expand the toast view when it has reach the maximum vertical position, override the widthForExpandedToastView() method and return the new width

override func widthForExpandedToastView() -> CGFloat? {
    return 190.0


The ToastCollectionViewCell offers a preRaiseToastView(toPosition: CGFloat) method that allows you to force some Toast views to be risen. It’s useful for example for the first cells that appears when you present the CollectionView, so they don’t pop only when the user starts to scroll.


By implementing the ToastCollectionViewCellDelegate, you can be notified when any of your Toast views get to
their top position, meaning they are fully raised.

You can then trigger an action on the given Toast view.


class ExampleCell: ToastCollectionViewCell, ToastCollectionViewCellDelegate {
    func onToastFullyRaised(toast: UIView) {
        let toast = toast as! MyToastView
