Set delegate for IronSource mobile ads

Question

I am following this tutorial however I cannot figure out how to set the delegate. I have everything else set up and the ad is displaying but I can not run any code when the ad is closed because I am not sure how to set up the delegate. I tried to use my ad placement name but that wasn't it so I am not sure how I would set up the delegate in this case.

class DetailViewController: ISRewardedVideoDelegate {

@IBAction func ironSourceActionAd(_ sender: Any) {

    IronSource.showRewardedVideo(with:UIViewController(), placement: "DefaultRewardedVideo")
}

public func rewardedVideoHasChangedAvailability(_ available: Bool) {
}

public func rewardedVideoDidEnd() {
}

public func rewardedVideoDidStart() {
}

public func rewardedVideoDidClose() {
    text()
    print("closed")
}

public func rewardedVideoDidOpen() {
   print("Opened")
}

public func rewardedVideoDidFailToShowWithError(_ error: Error!) {
}

public func didReceiveReward(forPlacement placementInfo: ISPlacementInfo!) {
}
public func didClickRewardedVideo(_ placementInfo: ISPlacementInfo!) {
}


override func viewDidLoad() {
    super.viewDidLoad()
    IronSource.initWithAppKey("72c23e35")
  error here//  IronSource.setRewardedVideoDelegate(DetailViewController)
    ISIntegrationHelper.validateIntegration()

}

Answer 1

The tutorial's Step 2 teaches how to set up delegate. It seems like you need to complete Step 2 first, before Step 3, and Step 4.

Answer 2

It could be that you haven't set the UserID. From the Ironsource help docs:

Make sure you’ve set the userID before you initialize the ironSource SDK in order to successfully reward your users.

Here is how I did it in my viewDidLoad function:

    // Ironsource set up
    IronSource.setRewardedVideoDelegate(self)

    let userID = IronSource.advertiserId() // Ironsource generates a userID automatically for each user
    IronSource.setUserId(userID)

    let appKey = "xxxxxxx" // from my Ironsource dashboard
    IronSource.initWithAppKey(appKey, adUnits: [IS_REWARDED_VIDEO])
