# Add app event tracker on ios app

### step 1 -> step 5: configurate finished

### steep 6
* Connect Your App Delegate and Scene Delegate

//  AppDelegate.swift

import UIKit
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
          
        ApplicationDelegate.shared.application(
            application,
            didFinishLaunchingWithOptions: launchOptions
        )

        return true
    }
          
    func application(
        _ app: UIApplication,
        open url: URL,
        options: [UIApplication.OpenURLOptionsKey : Any] = [:]
    ) -> Bool {

        ApplicationDelegate.shared.application(
            app,
            open: url,
            sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
            annotation: options[UIApplication.OpenURLOptionsKey.annotation]
        )

    }  

}

    


* **If you are using iOS 13 or above please add the following method to your SceneDelegate:**

//  SceneDelegate.swift

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    guard let url = URLContexts.first?.url else {
        return
    }

    ApplicationDelegate.shared.application(
        UIApplication.shared,
        open: url,
        sourceApplication: nil,
        annotation: [UIApplication.OpenURLOptionsKey.annotation]
    )
}

### step 7
* add app event manually

/**
 * For more details, please take a look at:
 * developers.facebook.com/docs/reference/ios/current/class/FBSDKAppEvents
 */
- (void)logCompleteRegistrationEvent:(NSString *)registrationMethod {
    NSDictionary *params =
    @{FBSDKAppEventParameterNameRegistrationMethod : registrationMethod};
    [FBSDKAppEvents
     logEvent:FBSDKAppEventNameCompletedRegistration
     parameters:params];
}

### step 8
1. Open the [App Ads Helper](https://developers.facebook.com/tools/app-ads-helper/)
2. In **Select an App**, choose your app and choose **Submit**
3. Scroll the bottom and choose **Test Event**
