|
@IBOutlet weak var collectionView: NSCollectionView!
|
|
|
|
override func viewDidLoad() {
|
|
self.collectionView.register(CustomCollectionViewItem.self, forItemWithIdentifier: NSUserInterfaceItemIdentifier("CustomCollectionViewItem"))
|
|
}
|
|
}
|
|
|
|
extension CustomViewController: NSCollectionViewDataSource {
|
|
func collectionView(_ collectionView: NSCollectionView, numberOfItemsInSection section: Int) -> Int {
|
|
return dataSource.count
|
|
}
|
|
|
|
func collectionView(_ collectionView: NSCollectionView, itemForRepresentedObjectAt indexPath: IndexPath) -> NSCollectionViewItem {
|
|
let item = self.collectionView.makeItem(withIdentifier: NSUserInterfaceItemIdentifier("CustomCollectionViewItem"), for: indexPath)
|
|
return item
|
|
}
