How would I be able to change collection view flow layout to a compositional layout from storyboard. So I have a TabBarController class that contains 3 nav controllers that I init from storyboard looks like this.
//Storyboard is an enum that contains strings IDs that belong to controllers from main storyboard.
private func createNewViewController(storyboardIdentifier: Storyboard.Controller) -> UIViewController {
let controller = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: storyboardIdentifier.indentifer)
return controller
}
This is how I add the controllers to the tab bar controller.
viewControllers = [
SearchCollectionVC(),
//createNewViewController(storyboardIdentifier: .searchNav),
createNewViewController(storyboardIdentifier: .todayNav),
createNewViewController(storyboardIdentifier: .appsNav)
]
If I try to add my SearchCollectionVC with the commented line my app crashes. It executes the line fatalError() in the required init from the SearchCollectionVC. This is how I create the layout.
init() {
super.init(collectionViewLayout: SearchCollectionVC.createCollectionLayout())
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
static func createCollectionLayout() -> UICollectionViewCompositionalLayout {
let itemSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1), heightDimension: .fractionalHeight(1))
let item = NSCollectionLayoutItem(layoutSize: itemSize)
let grupSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1), heightDimension: .absolute(250))
let group = NSCollectionLayoutGroup.horizontal(layoutSize: grupSize, subitems: [item])
let section = NSCollectionLayoutSection(group: group)
section.interGroupSpacing = 20
let layout = UICollectionViewCompositionalLayout(section: section)
return layout
}
Now I tried doing this in the SearchCollectionVC viewDidLoad().
collectionView.collectionViewLayout = SearchCollectionVC.createCollectionLayout()
This works with the comment line and without the init. The thing is when I rotate the screen this happens.
This doesn't happen when I add the controller using SearchCollectionVC() and when using the init. Now, I don't know why this is happening. Can someone please let me know how would I be able to init a storyboard controller and change the layout to the compositional layout I created, without having the collection view getting cut in half.Thanks
