![]() ![]() minimumScaledItemSize enables the dimensions of the collection view cell items to be scaled upwards, to fill the width of the collection view’s contentSize. horizontalFlow layout extends UICollectionViewFlowLayout by adding a new optional property: minimumScaledItemSize. Important: this layout ignores the estimatedItemSize property, even if it is assigned. Multiple sections are supported, though cells in all sections will scroll simultaneously, so single section collections are most common. Alternatively, the developer can implement the UICollectionViewDelegateFlowLayout to specify unique sizes for each cell item.Ī developer may optionally return views to the UICollectionViewDataSource collectionView(_:viewForSupplementaryElementOfKind:at:) method, to set ‘supplementary’ views to the collection view’s section header or footer. Items in a section extend in a single row to infinity, so items will not wrap to new lines.Ī developer should set the itemSize property of the layout to specify the standard dimensions of the cell items. This layout should be used when the user should pan horizontally in the collection view, to view items off-screen to the left or right. horizontalScroll layout extends UICollectionViewFlowLayout. UICollectionViewLayout subclasses FUICollectionViewLayout.horizontalScroll Then, the developer can use one or more of the UICollectionViewLayout types from the SAPFiori framework to govern the item layout, and/or choose from the available UICollectionViewCell subclasses in the framework to match the design specification. These controls implement some context-specific behavior for the collection view–usually around layout and sizing–but when starting to implement a custom collection case, the starting point for a developer should be to work directly with * UICollectionView***. ![]() FUITableViewCollectionSection with embedded FUICollectionViewTableViewCell.The SAPFiori controls exposing a collection view property include: A developer should use the regular UIKit API’s to configure and populate the item views of the collection, and handle things like taps and transitions. When the content for those controls should be managed by the developer, it typically exposes the collection view as a public property in the API. The SAPFiori utilizes UICollectionView instances in a number of controls. The Fiori Design Language utilizes collection views in a number of floorplans, especially Object Details, Overview, as well as in the Gallery View, Object CollectionView and Attachments section of the Create View. The UICollectionView is a key view type in UIKit and Apple’s Human Interface Guidelines. Collection views UICollectionView controls ![]()
