How to build a UICollectionView like the App Store

iOS 13 introduced powerful new collection view features, including UICollectionViewDiffableDataSource and UICollectionViewCompositionalLayout, so in this video I walk you through how to use these features and more to make a collection view that looks just like Apple's App Store.
You can find the source code for this project on GitHub: github.com/twostraws/TapStore
If you want to find out more about what's new in iOS 13, I've put together a massive collection of code samples here: www.hackingwithswift.com/arti...

I've added a small extension to the protocol: extension SelfConfiguringCell { static var reuseIdentifier: String { return String(describing: self) } } This way we can omit to set the reuseIdentifier manually for every cell that conforms to the protocol :)

Awesome video, Paul 👏 I wonder why the corner radius did not work for the featured cell's image view 🤔

@twostraws 4 жыл бұрын

My images were slightly the wrong size, and I used aspect fit for the content mode. If you try aspect fill (i.e., stretch to fit) you'll see the corner rounding work. I should probably fix this up in the GitHub repo - it wouldn't take much.

Can someone please tell me how to decide the estimated height magic number? When I tried to build this myself, I used a different number and my layout didn't turn out to be like the finished app. And I started to think my constraints in the cell might be wrong. Any help would be appreciated. Thanks.

Great efforts sir, but I noticed an issue. After implementing the UICollectionViewCompositionalLayout, the delegate methods of UICollectionView/UIScrollView stopped working. Please do share a reliable workaround.

@Byyaroff 4 жыл бұрын

Hello Paul. Thank you very much for this amazing tutorial. I faced one small problem (I think it is a bug of UICollection). All horizontal scrolled sections with Headers but without subtitles shifted right a little bit in the beginning and when I touch it or scroll this sections animated moves to their proper place. Can you please tell how to fix it? I've found this issue but non of the solutions really helped: stackoverflow.com/questions/59685203/uicollectionviewcompositionallayout-with-grouppagingcentered-doesnt-start-cente/63494677

Very helpful content! Question: do you know how to get the scrolling events of orthogonal scrolling? I can use collectionView's delegate to get the scrolling events of scrolling vertically (as in the example in the video), but how can I get the scrolling events of scrolling horizontally (as in the first section of the example in the video)?

@jeffwang4448 4 жыл бұрын

same question!

@shaneqi 4 жыл бұрын

@@jeffwang4448 Alright, so I got it working by finding the scroll view for the orthogonal scrolling (it uses a separated scroll view embedded in the collection view), and switched out its delegate to my class. But I had to store its default delegate somewhere and call delegate method on it in every scroll view delegate method, otherwise it would have weird behaviors. Talk to me on Telegram if you have problems understanding what I said, my id is @ShaneQi.

@@nickn5206 Yes I Did. Create the array like so: var gamesModel: [MenuItems] = [] struct MenuItems { var title: String var sbID: String var segueID: String } Then add the array items like so: gamesModel.append(MenuItems(title:"Fun Game", sbID:"Main", segueID:"funGameVC" )) sbID = Storyboard file name which contains the VC you want to move to. segueID = Segue ID you give the View controller you want to move to Then in the didSelectItemAt section use them like so: let arrayIndexRow = gamesModel[indexPath.row] let segueID = arrayIndexRow.segueID let storyboardID = arrayIndexRow.sbID let storyboard = UIStoryboard(name: storyboardID, bundle: nil) let vc = (storyboard.instantiateViewController(identifier: segueID)) self.navigationController?.pushViewController(vc, animated: true) Hope this helps as it took me a long time to figure all this out and get it working.
