# Rewarded

## Integration

Just as interstitials, rewarded ads can only be integrated with code. Below we show a simple example to understand how it works:

{% tabs %}
{% tab title="Swift" %}

```swift
import UIKit
import WortiseSDK

class ViewController: UIViewController {

    private var rewardedAd: WARewardedAd!

    override func viewDidLoad() {
        super.viewDidLoad()
        ...
        rewardedAd = WARewardedAd(adUnitId: "test-rewarded")
        rewardedAd.loadAd()
    }

    override func willMove(toParent controller: UIViewController?) {
        super.willMove(toParent: controller)
        ...
        rewardedAd.destroy()
    }

    func showRewarded() {
        if rewardedAd.isAvailable {
            rewardedAd.showAd(from: self)
        }
    }
}
```

{% endtab %}
{% endtabs %}

## **Delegate configuration**

Like occurs with other formats, a listener can be set to receive the events that happen during the rewarded lifecycle. For this, it is needed to implement the `WARewardedDelegate` interface just as shown in the example below:

{% tabs %}
{% tab title="Swift" %}

```swift
extension ViewController : WARewardedDelegate {
    
    func didClick(rewardedAd: WARewardedAd) {
        // Invoked when the ad has been clicked
    }

    func didComplete(rewardedAd: WARewardedAd, reward: WAReward) {
        // Invoked when the ad has been completed
    }

    func didDismiss(rewardedAd: WARewardedAd) {
        // Invoked when the ad has been dismissed
    }
    
    func didFailToLoad(rewardedAd: WARewardedAd, error: WAAdError) {
        // Invoked when the ad could not be loaded
        // (because of an error or no fill)
    }

    func didFailToShow(rewardedAd: WARewardedAd, error: WAAdError) {
        // Invoked when the ad could not be shown
    }

    func didImpress(rewardedAd: WARewardedAd) {
        // Invoked when the ad has generated an impression
    }

    func didLoad(rewardedAd: WARewardedAd) {
        // Invoked when the ad has been loaded
    }
    
    func didPayRevenue(rewardedAd: WARewardedAd, data: WARevenuedata) {
        // Invoked when the ad has generated revenue
    }
 
    func didShow(rewardedAd: WARewardedAd) {
        // Invoked when the ad has been shown
    }
}
```

Once the interface is implemented, the delegate is assigned to the ad instance:

```swift
rewardedAd.delegate = self
```

{% endtab %}
{% endtabs %}
