How to integrate admob ads in ios app

To integrate AdMob ads into your iOS app, you’ll need to follow these general steps:

1. Create a Google AdMob Account:
   Go to the Google AdMob website (https://admob.google.com/) and sign up or log in with your Google account. Once logged in, create a new app or select an existing app to integrate AdMob ads.
2. Add Your App to Google AdMob:
   After creating your app in the Google AdMob Dashboard, you need to add your iOS app to the app settings. You’ll need to provide your app’s bundle ID.
3. Set Up Google Mobile Ads SDK:
   Add the Google Mobile Ads SDK to your iOS project using CocoaPods or manually. Using CocoaPods:
   Add the following line to your Podfile and run pod install:

   pod 'Google-Mobile-Ads-SDK'

Manually:
Download the Google Mobile Ads SDK from the Google AdMob website and follow the instructions to add it to your Xcode project.

4. Initialize Google Mobile Ads SDK:
   In your AppDelegate or ViewController, initialize the Mobile Ads SDK with your AdMob app ID.

   // Swift
   import GoogleMobileAds

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
       GADMobileAds.sharedInstance().start(completionHandler: nil)
       return true
   }

5. Add Google Ad Components:
   Add Google ad components to your view controller’s storyboard or programmatically. Example Banner Ad:

   // Swift
   import GoogleMobileAds

   class ViewController: UIViewController, GADBannerViewDelegate {

       var bannerView: GADBannerView!

       override func viewDidLoad() {
           super.viewDidLoad()

           bannerView = GADBannerView(adSize: kGADAdSizeBanner)
           bannerView.adUnitID = "YOUR_AD_UNIT_ID"
           bannerView.rootViewController = self
           bannerView.delegate = self
           addBannerViewToView(bannerView)

           let request = GADRequest()
           bannerView.load(request)
       }

       func addBannerViewToView(_ bannerView: GADBannerView) {
           bannerView.translatesAutoresizingMaskIntoConstraints = false
           view.addSubview(bannerView)
           view.addConstraints([
               NSLayoutConstraint(item: bannerView,
                                  attribute: .bottom,
                                  relatedBy: .equal,
                                  toItem: view.safeAreaLayoutGuide,
                                  attribute: .bottom,
                                  multiplier: 1,
                                  constant: 0),
               NSLayoutConstraint(item: bannerView,
                                  attribute: .centerX,
                                  relatedBy: .equal,
                                  toItem: view,
                                  attribute: .centerX,
                                  multiplier: 1,
                                  constant: 0)
           ])
       }

       func bannerViewDidReceiveAd(_ bannerView: GADBannerView) {
           // Ad loaded successfully
       }

       func bannerView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: Error) {
           // Handle ad loading error
       }
   }

6. Load Google Ads:
   In your view controller, load the ad into the ad view.

   // Swift
   bannerView.load(request)

7. Handle Ad Events:
   Implement delegate methods to handle events such as ad loading, clicks, and errors.

   // Swift
   func bannerViewDidReceiveAd(_ bannerView: GADBannerView) {
       // Ad loaded successfully
   }

   func bannerView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: Error) {
       // Handle ad loading error
   }

8. Test Your Integration:
   Before releasing your app, make sure to test your Google ads integration using test ads provided by Google. You can use test ad unit IDs to see test ads.
9. Publish Your App:
   After testing, you can publish your app with Google ads integrated.

Remember to comply with Google’s advertising policies and guidelines when integrating and displaying ads in your app.
