Careful on the implementation of This needs to be implemented according to your implementation of the infinite scroll. EX: 20 items per page so first 20 items go from 0 to 19 and the first item of the second page is not 0 is 20 formula beeing -> pageItemIndex + (pageSize*currentPage) so first item position of first page is 0 + (20*0) item 0 plus 20 multiplied by the current page index, so page 1 has index 0 and first item position of the second page is 0 + (20*1) item 0 plus 20 multiplied by the current page index, so page 2 has index 1 second item first page would be 1 + (20*0) = 1 second item second page would be 1 + (20*1) = 21 and so on |
Lifecycle Events
There are two options available to track the advertisement events for the infinite scroll. You can subscribe to these events with the same method but passing a new object as a parameter. Details about this object can be found in the Reference.

import UIKit
import R89SDK
// 1. Extend from the Banner InfiniteScrollEventListener
class InfiniteScrollLifecycleListener: InfiniteScrollEventListener {
...
override func onAdItemLoaded(itemIdInData: Int32) {
// Ad has been loaded for the position (itemIdInData)
}
...
}
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
var collectionView: UICollectionView!
...
override func viewDidLoad() {
super.viewDidLoad()
// Configure the collection view layout
...
let infiniteScrollConfigId = ConfigBuilder.companion.INFINITE_SCROLL_TEST_R89_CONFIG_ID
RefineryAdFactory.shared.createInfiniteScroll(
configurationID: infiniteScrollConfigId,
scrollView: self.collectionView,
scrollItemAdWrapperTag: "infiniteScroll_ad_wrapper_tag",
// 2. Pass the InfiniteScrollLifecycleListener instance via lifecycleCallbacks
lifecycleCallbacks: InfiniteScrollLifecycleListener())
}
...
} |

The same lifecycleCallbacks parameter is available for the createInfiniteScrolland createManualInfiniteScroll methods.
While using the manual approach additionally ad lifecycle methods could be observed for each cell/item by passing the BannerEventListener’s instance to getInfiniteScrollAdForIndex method in a following way
