Initialize the SDK in iOS

ViewController.h

ViewController.h

In your ViewController header (.h), import Unity Ads and set the following delegates:

• handles callbacks for initialization succeeding or failing.
• handles callbacks for Ad Units succeeding or failing to load content.
• handles callbacks for Ad Units succeeding or failing to show loaded content.

#import <UnityAds/UnityAds.h>
 
@interface ViewController : UIViewController<UnityAdsInitializationDelegate,
UnityAdsLoadDelegate,
UnityAdsShowDelegate>
 
@property (assign, nonatomic) BOOL testMode;

ViewController.m

ViewController.m

To initialize the SDK, you must reference your project's Game ID for the appropriate platform. You can locate the ID in the Unity Ads Monetization dashboard by selecting CURRENT PROJECT > Settings from the secondary navigation menu

In your ViewController implementation (.m), create a delegate to handle initialization callbacks, and reference it as a parameter in the method.

- (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view.
  [UnityAds
    initialize:kDefaultGameId
    testMode:self.testMode
    initializationDelegate:self];
}

// Implement initialization callbacks to handle success or failure:
#pragma mark : UnityAdsInitializationDelegate
- (void)initializationComplete {
  NSLog(@" - UnityAdsInitializationDelegate initializationComplete" );
  // Pre-load an ad when initialization succeeds, so it is ready to show:
  [UnityAds load:@"Interstitial_iOS" loadDelegate:self];
}

- (void)initializationFailed:(UnityAdsInitializationError)error withMessage:(NSString *)message {
   NSLog(@" - UnityAdsInitializationDelegate initializationFailed with message: %@", message );
}

// Implement load callbacks to handle success or failure after initialization:
#pragma mark: UnityAdsLoadDelegate
- (void)unityAdsAdLoaded:(NSString *)placementId {
  NSLog(@" - UnityAdsLoadDelegate unityAdsAdLoaded %@", placementId);
}

- (void)unityAdsAdFailedToLoad:(NSString *)placementId
       withError:(UnityAdsLoadError)error
     withMessage:(NSString *)message {
   NSLog(@" - UnityAdsLoadDelegate unityAdsAdFailedToLoad %@", placementId);
}
