# Fullscreen (Interstitial)

This guide shows you how to integrate fullscreen ads of RTBSDK into your app.

### Create RTBFullscreenAd Instance

Create an instance of [`RTBFullscreenAd`](https://ios-sdk-rtb.gravite.net/references/documentation/rtbsdk/rtbfullscreenad):

```swift
let fullscreenAd = RTBFullscreenAd()
```

### Listen to Callbacks

Through the use of [`RTBFullscreenDelegate`](https://ios-sdk-rtb.gravite.net/references/documentation/rtbsdk/rtbfullscreendelegate), you can listen to the different callbacks. Of course, your class must conform to its delegate methods (see the [complete example below](#complete-code-example)).

```swift
fullscreenAd.delegate = self
```

### Request Ad

To load a fullscreen ad, you will need to pass an instance of [RTBFullscreenRequestConfiguration](https://ios-sdk-rtb.gravite.net/references/documentation/rtbsdk/rtbfullscreenrequestconfiguration) with `placementID` and the `iTunesAppId`. Please contact our [support](mailto:support@gravite.net) for getting the needed IDs.

```swift
let configuration = RTBFullscreenRequestConfiguration(placementId: <PLACEMENT_ID>, iTunesAppId: "<ITUNES_APP_ID>")
configuration.sellerId = "<SELLERID>"
configuration.bidFloor = <BID_FLOOR>
fullscreenAd.load(configuration: configuration)
```

You will be notified about the loading success/failure through the [`RTBFullscreenDelegate`](https://ios-sdk-rtb.gravite.net/references/documentation/rtbsdk/rtbfullscreendelegate)&#x20;

### **Optional - set user targeting**

You can pass user targeting data to each request, allowing ads to be more relevant to your audience. Each field in [RTBUserTargeting](https://ios-sdk-rtb.gravite.net/references/documentation/rtbsdk/rtbusertargeting) is optional.

```swift
let configuration = RTBFullscreenRequestConfiguration(placementId: <PLACEMENT_ID>, iTunesAppId: "<ITUNES_APP_ID>")
configuration.userTargeting = .init(userId: "<USER_ID>", gender: .male, yearOfBirth: 1999, keywords: ["keyword1", "keyword2"])
// yearOfBirth must be a 4-digit number, otherwise, it will be ignored
```

### Show Ad

After the ad gets loaded, it can be presented by calling:

```swift
fullscreenAd.show(viewController: self)
```

> The currency of `bidFloor` and `priceCPM` parameters is USD.

### Complete Code Example <a href="#complete-code-example" id="complete-code-example"></a>

```swift
import RTBSDK

class ViewController: UIViewController {
    let fullscreenAd: RTBFullscreenAd = RTBFullscreenAd()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

    }
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        
        // [Important] Set fullscreen ad delegate to listen to the callbacks
        fullscreenAd.delegate = self
        
        // Prepare request configurations
        let configuration = RTBFullscreenRequestConfiguration(placementId: <PLACEMENT_ID>, iTunesAppId: "<ITUNES_APP_ID>")
        configuration.sellerId = "<SELLERID>"
        configuration.bidFloor = <BID_FLOOR>
        // Request a fullscreen ad using the placement ID and itunes app ID
        fullscreenAd.load(configuration: configuration)
    }
}

extension ViewController: RTBFullscreenDelegate {
    func fullscreenAdDidReceiveAd(_ fullscreenAd: RTBFullscreenAd, bidInfo: RTBBidInfo, networkName: String) {
        // A fullscreen ad has been loaded
        fullscreenAd.show(viewController: self)
    }

    func fullscreenAd(_ fullscreenAd: RTBFullscreenAd, didFailToReceiveAd errorMessage: String, networkName: String) {
        // Failed to load a fullscreen ad
    }

    func fullscreenAdDidRecordClick(_ fullscreenAd: RTBFullscreenAd, networkName: String) {
        // The fullscreen ad received a click
    }

    func fullscreenAdDidPauseForAd(_ fullscreenAd: RTBFullscreenAd, networkName: String) {
        // The app paused for displaying a fullscreen ad
    }

    func fullscreenAdDidResumeAfterAd(_ fullscreenAd: RTBFullscreenAd, networkName: String) {
        // The app resumed after dismissing a fullscreen ad
    }
}

```
