重用视图从其他存储库获取数据

Question

我有一个UIVIewController，它带有一个集合视图和一个自定义单元格，用于显示来自API端点的一些数据。

此数据是从以下代码中检索的：

private func getItems() {
        self.ItemsStartFetch(Text: "Fetching rooms", noItems: noRoomsViewContainer, itemsViewer: collectionContainer)

        let roomsController: RoomsController = RoomsController()
        roomsController.GetRooms { (status, items) in
            // Start Legacy Code
            RoomsController.rooms = items
            // End Legacy Code
            self.items = items
        self.ItemsRetrieved(noItemsView: self.noRoomsViewContainer, itemsViewer: self.collectionContainer , showViewer: (items.count > 0))
        self.roomCollection.reloadData()
    }
}

现在，我需要创建一个完全相同的视图，其中差异将从具有相同estructure的另一个终结点检索数据，但这一次它来自

private func getItems() {
        self.ItemsStartFetch(Text: "Fetching designs", noItems: noDesignsViewContainer, itemsViewer: collectionContainer)


    let designsController: DesignsController = DesignsController()
    designsController.GetDesigns { (status, items) in
        // Start Legacy Code
        DesignsController.Designs = items
        // End Legacy Code
        self.items = items
        self.ItemsRetrieved(noItemsView: self.noDesignsViewContainer, itemsViewer: self.collectionContainer , showViewer: (items.count > 0))
        self.designsCollection.reloadData()
    }
} 

如何将要使用的控制器注入UIViewConroller？
