Rewarded Ads

Overview

Rewarded ads are full-screen video ads that provide rewards such as in-game currency, lives, or hints when users watch the video to completion.

Key Features

Full-screen video ads
Rewards only provided when user completely watches the ad
User chooses to watch ad (e.g., “Watch video to get lives” button)
Configurable reward type and amount

Use test unit ID in development environment: PUBLIC_TEST_UNIT_ID_REWARDED

Implementation Steps

Implement rewarded ads in the following steps:

Create AdropRewardedAd Instance - Create ad object with unit ID
Set Delegate - Set delegate to handle ad events
Load Ad - Request ad using load() method
Show Ad - Display ad using show() method and handle rewards

Swift Example

Basic Implementation

import UIKit
import AdropAds

class RewardedViewController: UIViewController {
    private var rewardedAd: AdropRewardedAd?

    override func viewDidLoad() {
        super.viewDidLoad()

        // 1. Create AdropRewardedAd instance
        rewardedAd = AdropRewardedAd(unitId: "YOUR_UNIT_ID")

        // 2. Set delegate
        rewardedAd?.delegate = self

        // 3. Load ad
        rewardedAd?.load()
    }

    @IBAction func showRewardedAdButtonTapped(_ sender: UIButton) {
        // Check if ad is loaded
        guard rewardedAd?.isLoaded == true else {
            print("Ad not loaded yet")
            return
        }

        // 4. Show ad and handle reward
        rewardedAd?.show(fromRootViewController: self) { [weak self] type, amount in
            // Grant reward
            print("Reward earned - Type: \(type), Amount: \(amount)")
            self?.grantReward(type: type, amount: amount)
        }
    }

    private func grantReward(type: Int, amount: Int) {
        // Grant reward to user
        // Example: Add game currency, restore lives, etc.

        // Important: It is recommended to verify rewards on your server
        // Processing rewards only on the client side allows cheating
    }
}

// MARK: - AdropRewardedAdDelegate
extension RewardedViewController: AdropRewardedAdDelegate {
    // Required: Ad received successfully
    func onAdReceived(_ ad: AdropRewardedAd) {
        print("Ad received")
        // Enable watch ad button, etc.
    }

    // Required: Ad receive failed
    func onAdFailedToReceive(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) {
        print("Ad receive failed: \(errorCode)")
        // Keep watch ad button disabled, etc.
    }

    // Optional: Ad impression
    func onAdImpression(_ ad: AdropRewardedAd) {
        print("Ad impression")
    }

    // Optional: Ad clicked
    func onAdClicked(_ ad: AdropRewardedAd) {
        print("Ad clicked")
    }

    // Optional: Before showing full screen ad
    func onAdWillPresentFullScreen(_ ad: AdropRewardedAd) {
        print("About to show ad")
        // Pause background music, etc.
    }

    // Optional: After showing full screen ad
    func onAdDidPresentFullScreen(_ ad: AdropRewardedAd) {
        print("Ad shown")
    }

    // Optional: Before dismissing full screen ad
    func onAdWillDismissFullScreen(_ ad: AdropRewardedAd) {
        print("About to dismiss ad")
    }

    // Optional: After dismissing full screen ad
    func onAdDidDismissFullScreen(_ ad: AdropRewardedAd) {
        print("Ad dismissed")
        // Resume background music, etc.

        // Preload next ad
        rewardedAd?.load()
    }

    // Optional: Ad show failed
    func onAdFailedToShowFullScreen(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) {
        print("Ad show failed: \(errorCode)")
    }
}

Delegate Methods

Required Methods

onAdReceived(_:)

void

Called when ad is received successfully. You can show the ad using show() method from this point.

onAdFailedToReceive(_:_:)

void

Called when ad fails to load. You can check the cause of failure through the error code.

Optional Methods

onAdImpression(_:)

void

Called when ad impression is recorded and sent.

onAdClicked(_:)

void

Called when user clicks the ad.

onAdWillPresentFullScreen(_:)

void

Called just before the ad screen is displayed. You can pause background music, etc.

onAdDidPresentFullScreen(_:)

void

Called after the ad screen is fully displayed.

onAdWillDismissFullScreen(_:)

void

Called just before the ad screen is dismissed.

onAdDidDismissFullScreen(_:)

void

Called after the ad screen is fully dismissed. You can resume background music or preload the next ad.

onAdFailedToShowFullScreen(_:_:)

void

Called when ad fails to show. You can check the cause of failure through the error code.

Closure Callbacks

As an alternative to delegates, you can use closure-based callbacks.

let rewardedAd = AdropRewardedAd(unitId: "YOUR_UNIT_ID")

// Required
rewardedAd.onAdReceived = { ad in
    print("Ad received")
}
rewardedAd.onAdFailedToReceive = { ad, errorCode in
    print("Ad failed: \(errorCode)")
}

// Optional
rewardedAd.onAdImpression = { ad in print("Ad impression") }
rewardedAd.onAdClicked = { ad in print("Ad clicked") }
rewardedAd.onAdWillPresentFullScreen = { ad in print("Ad will present") }
rewardedAd.onAdDidPresentFullScreen = { ad in print("Ad did present") }
rewardedAd.onAdWillDismissFullScreen = { ad in print("Ad will dismiss") }
rewardedAd.onAdDidDismissFullScreen = { ad in print("Ad did dismiss") }
rewardedAd.onAdFailedToShowFullScreen = { ad, errorCode in print("Ad failed to show: \(errorCode)") }

If both a delegate and closures are set, both will be called.

Reward Handling

Reward Callback

Pass the reward callback through the userDidEarnRewardHandler parameter of the show() method.

rewardedAd?.show(fromRootViewController: self) { type, amount in
    // type: Reward type (Int)
    // amount: Reward amount (Int)
    print("Reward earned - Type: \(type), Amount: \(amount)")
}

Reward Type and Amount

type: Reward type set in Ad Control Console (integer value)
amount: Reward amount set in Ad Control Console (integer value)

Server-Side Verification

Server-side verification (SSV) allows you to verify reward grants on your server, preventing client-side manipulation. Use AdropServerSideVerificationOptions to pass user identification and custom data that will be included in the server-to-server callback.

To receive SSV callbacks on your server, register a callback URL in the console: [Management] > [Integrations] > Reward Ad SSV. The userId and customData set here are included in the encrypted payload sent to that URL. See the Reward Ad SSV guide for payload decryption and setup.

Setting Up SSV

let rewardedAd = AdropRewardedAd(unitId: "YOUR_UNIT_ID")
rewardedAd.delegate = self

// Set server-side verification options before loading the ad
let ssvOptions = AdropServerSideVerificationOptions(
    userId: "user_12345",
    customData: "extra_info"
)
rewardedAd.serverSideVerificationOptions = ssvOptions

rewardedAd.load()

AdropServerSideVerificationOptions

Property	Type	Description
`userId`	`String?`	User identifier for server-side verification
`customData`	`String?`	Custom data string to include in the callback

// Initialize with parameters
let options = AdropServerSideVerificationOptions(
    userId: "user_12345",
    customData: "level_5_reward"
)

// Or set properties individually
let options = AdropServerSideVerificationOptions()
options.userId = "user_12345"
options.customData = "level_5_reward"

rewardedAd.serverSideVerificationOptions = options

Set serverSideVerificationOptions before calling load(). The userId and customData values are sent to your server callback URL when the user earns a reward.

Best Practices

1. Preload Ads

Preload ads for better user experience.

class GameViewController: UIViewController {
    private var rewardedAd: AdropRewardedAd?

    override func viewDidLoad() {
        super.viewDidLoad()

        // Preload ad when entering screen
        loadRewardedAd()
    }

    private func loadRewardedAd() {
        rewardedAd = AdropRewardedAd(unitId: "YOUR_UNIT_ID")
        rewardedAd?.delegate = self
        rewardedAd?.load()
    }

    private func showRewardedAd() {
        rewardedAd?.show(fromRootViewController: self) { [weak self] type, amount in
            self?.grantReward(type: type, amount: amount)
        }
    }
}

extension GameViewController: AdropRewardedAdDelegate {
    func onAdReceived(_ ad: AdropRewardedAd) {
        print("Rewarded ad ready")
    }

    func onAdFailedToReceive(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) {
        print("Ad load failed: \(errorCode)")
    }

    func onAdDidDismissFullScreen(_ ad: AdropRewardedAd) {
        // Preload next ad after ad is dismissed
        loadRewardedAd()
    }
}

2. Check Ad Ready State

Check if ad is loaded and update UI.

class GameViewController: UIViewController {
    @IBOutlet weak var watchAdButton: UIButton!
    private var rewardedAd: AdropRewardedAd?
    private var isAdReady = false

    private func updateButtonState() {
        watchAdButton.isEnabled = isAdReady
        watchAdButton.alpha = isAdReady ? 1.0 : 0.5
        watchAdButton.setTitle(
            isAdReady ? "Watch video to get lives" : "Loading ad...",
            for: .normal
        )
    }
}

extension GameViewController: AdropRewardedAdDelegate {
    func onAdReceived(_ ad: AdropRewardedAd) {
        isAdReady = true
        updateButtonState()
    }

    func onAdFailedToReceive(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) {
        isAdReady = false
        updateButtonState()
    }

    func onAdDidDismissFullScreen(_ ad: AdropRewardedAd) {
        isAdReady = false
        updateButtonState()

        // Load next ad
        rewardedAd?.load()
    }
}

3. Background Music Handling

Control background music appropriately before and after showing ads.

extension GameViewController: AdropRewardedAdDelegate {
    func onAdReceived(_ ad: AdropRewardedAd) { }
    func onAdFailedToReceive(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) { }

    func onAdWillPresentFullScreen(_ ad: AdropRewardedAd) {
        // Pause background music before showing ad
        AudioManager.shared.pauseBackgroundMusic()
    }

    func onAdDidDismissFullScreen(_ ad: AdropRewardedAd) {
        // Resume background music after ad ends
        AudioManager.shared.resumeBackgroundMusic()
    }
}

4. Error Handling

Implement retry logic when ad loading fails.

extension GameViewController: AdropRewardedAdDelegate {
    func onAdFailedToReceive(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) {
        print("Ad load failed: \(errorCode)")

        // Retry for network errors
        if errorCode == .ERROR_CODE_NETWORK {
            DispatchQueue.main.asyncAfter(deadline: .now() + 3.0) { [weak self] in
                self?.rewardedAd?.load()
            }
        }
    }

    func onAdFailedToShowFullScreen(_ ad: AdropRewardedAd, _ errorCode: AdropErrorCode) {
        print("Ad show failed: \(errorCode)")

        // Notify user
        showAlert(message: "Unable to show ad. Please try again later.")
    }
}

5. Memory Management

Clean up ad object when ViewController is deallocated.

class GameViewController: UIViewController {
    private var rewardedAd: AdropRewardedAd?

    deinit {
        rewardedAd?.delegate = nil
        rewardedAd = nil
    }
}

Testing

Test Unit ID

Always use a test unit ID during development.

// Development environment
let rewardedAd = AdropRewardedAd(unitId: "PUBLIC_TEST_UNIT_ID_REWARDED")

// Production environment
let rewardedAd = AdropRewardedAd(unitId: "YOUR_PRODUCTION_UNIT_ID")

Testing with a real unit ID may be considered invalid traffic and could result in account suspension. Always use a test unit ID.

Managing Unit IDs by Environment

Automatically switch unit IDs based on build configuration.

enum AdUnitID {
    static var rewarded: String {
        #if DEBUG
        return "PUBLIC_TEST_UNIT_ID_REWARDED"
        #else
        return "YOUR_PRODUCTION_UNIT_ID"
        #endif
    }
}

// Usage
let rewardedAd = AdropRewardedAd(unitId: AdUnitID.rewarded)
