CollectionViewDelegateSlantedLayout

@objc
public protocol CollectionViewDelegateSlantedLayout : UICollectionViewDelegate

The CollectionViewDelegateSlantedLayout protocol defines methods that let you coordinate with a CollectionViewSlantedLayout object to implement a slanted layout. The methods of this protocol define the size of items.

Getting the Size of Items

  • Asks the delegate for the size of the specified item’s cell.

    If you do not implement this method, the slanted layout uses the values in its itemSize property to set the size of items instead. Your implementation of this method can return a fixed set of sizes or dynamically adjust the sizes based on the cell’s content.
