The Unity LevelPlay Interstitial is a full-screen ad unit, usually served at natural transition points during the app lifecycle.

注

This documentation is relevant for SDK 8.4.0+.

Prerequisites

Ensure that you have correctly integrated the LevelPlay SDK into your application. Integration is outlined here.
Ensure that you initialize the SDK using LevelPlay Initialization API.
Find the AdUnitID in LevelPlay dashboard.

Create Interstitial Ad Object

The creation of the interstitial ad object must be performed after receiving the onInitSuccess callback. The object is a reusable instance that can handle multiple loads and shows throughout the session. After creation, it should be used to load and show ads for the same ad unit. For more advanced implementations, you may create multiple interstitial ad objects if necessary.


self.interstitialAd = [[LPMInterstitialAd alloc] initWithAdUnitId:@"adUnitId"];


self.interstitialAd = LPMInterstitialAd(adUnitId: "adUnitId")

Implement Delegates

Implement the LPMInterstitialAdDelegate in your code to get informed of ad delivery.

It is recommended to set the delegate before loading the interstitial ad.
Each interstitial ad should have its own delegate implementation.
Delegate methods run on the main thread.


self.interstitialAd = [[LPMInterstitialAd alloc] initWithAdUnitId:@"adUnitId"]; self.interstitialAd.delegate = self;#pragma mark - LPMInterstitialAdDelegate Methods- (void)didLoadAdWithAdInfo:(LPMAdInfo *)adInfo {}- (void)didFailToLoadAdWithAdUnitId:(NSString *)adUnitId error:(NSError *)error {}- (void)didChangeAdInfo:(LPMAdInfo *)adInfo {}- (void)didDisplayAdWithAdInfo:(LPMAdInfo *)adInfo {}- (void)didFailToDisplayAdWithAdInfo:(LPMAdInfo *)adInfo error:(NSError *)error {}- (void)didClickAdWithAdInfo:(LPMAdInfo *)adInfo {}- (void)didCloseAdWithAdInfo:(LPMAdInfo *)adInfo {}


self.interstitialAd = LPMInterstitialAd(adUnitId: "adUnitId")self.interstitialAd.setDelegate(self)// MARK: LPMInterstitialAdDelegate methodsfunc didLoadAd(with adInfo: LPMAdInfo) {}func didFailToLoadAd(withAdUnitId adUnitId: String, error: Error) {}func didChangeAdInfo(_ adInfo: LPMAdInfo) {}func didDisplayAd(with adInfo: LPMAdInfo) {}func didFailToDisplayAd(with adInfo: LPMAdInfo, error: Error) {}func didClickAd(with adInfo: LPMAdInfo) {}func didCloseAd(with adInfo: LPMAdInfo) {}

LevelPlay Ad Info

The LPMAdInfo parameter includes information about the loaded ad. Learn more about its implementation and available fields here.

Load Interstitial Ad

To load an interstitial ad use loadAd.


[self.interstitialAd loadAd];


self.interstitialAd.loadAd()

Show Interstitial Ad

Show an interstitial ad after you receive the didLoadAd callback.

It is required to share ViewController.
If using placements, pass the placement name in the showAd API as shown in the Placements section below.
After the ad has been successfully displayed to the user, you can load another ad by repeating the loading step.


- (void)showInterstitialAd {    // Check that ad is ready    if ([self.interstitialAd isAdReady]) {        // Show without placement        [self.interstitialAd showAdWithViewController:self placementName:NULL];    }}


func showInterstitialAd() {    // Check that ad is ready    if self.interstitialAd.isAdReady() {        // Show without placement        self.interstitialAd.showAd(viewController: self, placementName: nil)    }}

Check Ad is Ready

To avoid show failures, and to make sure the ad could be displayed correctly, we recommend using the following API before calling the showAd API. isAdReady – returns true if ad was loaded successfully and ad unit is not capped, or false otherwise. isPlacementCapped – returns true when a valid placement is capped. If the placement is not valid, or not capped, this API will return false.


// Check that ad is ready and that the placement is not cappedif ([self.interstitialAd isAdReady] && ![LPMInterstitialAd isPlacementCapped:placementName]) {    [self.interstitialAd showAdWithViewController:self placementName:placementName];}


// Check that ad is ready and that the placement is not cappedif self.interstitialAd.isAdReady(), !LPMInterstitialAd.isPlacementCapped(placementName) {    self.interstitialAd.showAd(viewController: self, placementName: placementName)}

Placements

We support placements pacing and capping for interstitial on the LevelPlay dashboard. If placements are set up for interstitial ads, call the showAd method to serve the ad for a specific placement.


// Check that ad is ready and that the placement is not cappedif ([self.interstitialAd isAdReady] && ![LPMInterstitialAd isPlacementCapped:placementName]) {    // Show ad with placement    [self.interstitialAd showAdWithViewController:self placementName:@"PlacementName"];}


// Check that ad is ready and that the placement is not cappedif self.interstitialAd.isAdReady(), !LPMInterstitialAd.isPlacementCapped(placementName) {    // Show ad with placement    self.interstitialAd.showAd(viewController: self, placementName: placementName)}
