Overview

AdStage in-app events track user behavior and app events to support marketing analysis and optimization.

Key Features

Global Context Management: Set user/device information once and it's automatically included
Simple API: Easy to send with just event name and parameters
Automatic Session Tracking: Automatic session ID generation and management
Asynchronous Processing: Network communication doesn't block UI
Offline Support: Automatic retry when network is restored

Basic Setup

CocoaPods Configuration

Podfile

platform :ios, '12.0'
 
target 'YourApp' do
  use_frameworks!
  
  # AdStage SDK
  pod 'AdapterAdStage', '3.0.5'
  
  # Dependencies (automatically installed)
  # Alamofire, SwiftyJSON, etc.
end
 
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
    end
  end
end

Installation:

pod install

2. SDK Initialization

import AdapterAdStage
 
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        
        // Initialize AdStage
        AdStageManager.shared.initialize(
            apiKey: "your-api-key-here",
            serverUrl: "https://api.adstage.app"
        )
        
        print("✅ AdStage SDK initialization complete")
        
        return true
    }
}

3. Info.plist Configuration

<!-- Network permission -->
<key>NSAppTransportSecurity</key>

    <key>NSAllowsArbitraryLoads</key>
    <false/>
</dict>

Type-Safe Event Tracking

1. Simplest Approach

import AdapterAdStage
 
// Event without parameters
AdStageManager.shared.trackEvent(AdStageEvent.FirstOpen())
 
// Login event
AdStageManager.shared.trackEvent(
    AdStageEvent.Login(method: .email)
)

2. Purchase Event (Validation Example)

// ✅ GOOD: Provide value and currency together
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        value: 29.99,
        currency: "USD",
        transactionId: "TXN_123456"
    )
)
 
// ❌ BAD: Compile error when only value is provided!
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        value: 29.99  // ❌ Error: currency required!
    )
)
 
// ✅ GOOD: Only transactionId without currency
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        transactionId: "TXN_123456"
    )
)

3. Product View

// With parameters
AdStageManager.shared.trackEvent(
    AdStageEvent.ProductDetailsView(
        itemId: "PROD_123",
        itemName: "Wireless Earbuds"
    )
)
 
// Without parameters
AdStageManager.shared.trackEvent(AdStageEvent.ProductListView())

4. Custom Events (event_name Auto-Promotion)

For sending app-specific events beyond standard events, use AdStageEvent.Custom. When you include the event_name key in parameters, that value is automatically promoted as the actual event name and stored in the dashboard.

// Example: Send a custom event named 'promotion_click'
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(
        params: [
            "event_name": "promotion_click",
            "promotion_id": "summer_sale_2025",
            "screen": "home_banner"
        ]
    )
)
// Collected as "promotion_click" event in dashboard
 
// General custom event without event_name
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(
        params: [
            "action": "button_click",
            "button_id": "promo_banner",
            "screen": "home",
            "timestamp": Date().timeIntervalSince1970
        ]
    )
)
// Collected as "custom" event in dashboard
 
// Click and View also support free parameters
AdStageManager.shared.trackEvent(
    AdStageEvent.Click(
        params: [
            "campaign_id": "SUMMER2025",
            "ad_group": "electronics"
        ]
    )
)

    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        
        // Initialize SDK
        AdStageManager.shared.initialize(
            apiKey: "your-api-key",
            serverUrl: "https://api.adstage.app"
        )
        
        // First open event is sent automatically by SDK
        print("✅ App started")
        
        return true
    }
    
    func applicationDidEnterBackground(_ application: UIApplication) {
        print("📱 App entered background")
    }
    
    func applicationWillEnterForeground(_ application: UIApplication) {
        print("📱 App entered foreground")
    }
}

2. User Authentication

class AuthManager {
    
    // Sign Up
    func onSignUpComplete(method: String) {
        let signUpMethod: SignUpMethod
        switch method {
        case "email": signUpMethod = .email
        case "google": signUpMethod = .google
        case "apple": signUpMethod = .apple
        case "kakao": signUpMethod = .kakao
        case "naver": signUpMethod = .naver
        default: signUpMethod = .email
        }
        
        AdStageManager.shared.trackEvent(
            AdStageEvent.SignUp(method: signUpMethod)
        )
        
        print("✅ Sign up complete: \(method)")
    }
    
    // Login
    func onLoginSuccess(userId: String, method: String) {
        let loginMethod: SignUpMethod = method == "google" ? .google : .email
        
        AdStageManager.shared.trackEvent(

    // Logout
    func onLogout() {
        AdStageManager.shared.trackEvent(AdStageEvent.Logout())
        print("🚪 Logout")
    }
}

3. Screen Tracking (BaseViewController Pattern)

class BaseViewController: UIViewController {
    
    // Override in subclasses
    var screenName: String {
        return String(describing: type(of: self))
    }
    
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        trackScreenView()
    }
    
    private func trackScreenView() {
        AdStageManager.shared.trackEvent(
            AdStageEvent.ScreenView(
                screenName: screenName,
                screenClass: String(describing: type(of: self))
            )
        )
        
        print("📺 \(screenName)")
    }
}
 
// Usage example
class HomeViewController: BaseViewController {
    override var screenName: String { "home" }
}
 
class ProductDetailViewController: BaseViewController {
    override var screenName: String { "product_detail" }
    var productId: String?
    
    func loadProduct(_ productId: String) {
        self.productId = productId
        // Load data...
        
        // Product detail view event
        AdStageManager.shared.trackEvent(
            AdStageEvent.ProductDetailsView(
                itemId: productId,
                itemName: product.name
            )
        )
    }
}

        print("✅ Purchase complete: \(order.id), \(order.totalAmount) KRW")
    }
    
    // 10. Refund
    func trackRefund(order: Order) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Refund(
                transactionId: order.id,
                value: order.totalAmount,
                currency: "KRW"
            )
        )
    }
    
    // 11. Share
    func trackShare(product: Product, method: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Share(
                contentType: "product",
                itemId: product.id,
                method: method
            )
        )
    }
}

5. Game Events

class GameEventManager {
    
    // Tutorial
    func trackTutorialBegin(tutorialId: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.TutorialBegin(
                params: ["tutorial_id": tutorialId]
            )
        )
    }
    
    func trackTutorialComplete(tutorialId: String, duration: TimeInterval) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.TutorialComplete(
                params: [
                    "tutorial_id": tutorialId,
                    "duration_seconds": Int(duration)
                ]
            )
        )
    }
    
    // Level
    func trackLevelUp(level: Int, character: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.LevelUp(
                level: level,
                character: character
            )
        )
    }
    
    // Achievement
    func trackAchievement(achievementId: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Achievement(achievementId: achievementId)
        )
    }
    
    // Game Play
    func trackGameStart(level: Int, levelName: String, character: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.GamePlay(
                level: level,
                levelName: levelName,
                character: character,
                contentType: "pvp"
            )
        )
    }
    
    // Bonus Acquired
    func trackBonusAcquired(itemId: String, itemName: String, quantity: Int) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.AcquireBonus(
                contentType: "reward",
                itemId: itemId,
                itemName: itemName,
                quantity: quantity
            )
        )
    }
    
    // Virtual Currency
    func trackEarnCurrency(currencyName: String, amount: Double) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.EarnVirtualCurrency(
                virtualCurrencyName: currencyName,
                value: amount
            )
        )
    }
    
    func trackSpendCurrency(currencyName: String, amount: Double, itemName: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.SpendVirtualCurrency(
                virtualCurrencyName: currencyName,
                value: amount,
                itemName: itemName
            )
        )
    }
}

Best Practices

1. Using Extensions

// UIViewController+AdStage.swift
extension UIViewController {
    func trackScreen() {
        let screenName = String(describing: type(of: self))
            .replacingOccurrences(of: "ViewController", with: "")
            .lowercased()
        
        AdStageManager.shared.trackEvent(
            AdStageEvent.ScreenView(
                screenName: screenName,
                screenClass: String(describing: type(of: self))
            )
        )
    }
}
 
// Usage
class ProfileViewController: UIViewController {
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        trackScreen()  // ✅ Simple!
    }
}

2. Event Tracking in ViewModel

class ProductViewModel: ObservableObject {
    
    @Published var product: Product?
    
    func loadProduct(productId: String) {
        Task {
            do {
                let product = try await repository.getProduct(productId)
                self.product = product
                
                // Product view event
                AdStageManager.shared.trackEvent(
                    AdStageEvent.ProductDetailsView(
                        itemId: product.id,
                        itemName: product.name
                    )
                )
                
            } catch {
                print("Failed to load product: \(error)")
            }
        }
    }
    
    func addToCart(product: Product, quantity: Int) {
        Task {
            do {
                try await repository.addToCart(product, quantity: quantity)
                
                let item = EcommerceItem(
                    itemId: product.id,
                    itemName: product.name,
                    price: product.price,
                    quantity: quantity
                )
                
                AdStageManager.shared.trackEvent(
                    AdStageEvent.AddToCart(
                        value: product.price * Double(quantity),
                        currency: "KRW",
                        items: [item]
                    )
                )
                
            } catch {
                print("Failed to add to cart: \(error)")
            }
        }
    }
}

3. Using with SwiftUI

import SwiftUI
import AdapterAdStage
 
struct ProductDetailView: View {
    let productId: String
    @StateObject private var viewModel = ProductViewModel()
    
    var body: some View {
        VStack {
            // UI...
            
            Button("Add to Cart") {
                viewModel.addToCart(viewModel.product, quantity: 1)
                
                // Button click event
                AdStageManager.shared.trackEvent(
                    AdStageEvent.Custom(
                        params: [
                            "action": "add_to_cart_button",
                            "product_id": productId
                        ]
                    )
                )
            }
        }
        .onAppear {
            viewModel.loadProduct(productId: productId)
            
            // Screen view event
            AdStageManager.shared.trackEvent(
                AdStageEvent.ScreenView(
                    screenName: "product_detail",
                    screenClass: "ProductDetailView"
                )
            )
        }
    }
}

4. Event Wrapper Class

class AnalyticsManager {
    
    static let shared = AnalyticsManager()
    private init() {}
    
    func trackScreen(_ screenName: String, screenClass: String? = nil) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.ScreenView(
                screenName: screenName,
                screenClass: screenClass
            )
        )
        print("📺 Screen: \(screenName)")
    }
    
    func trackPurchase(_ order: Order) {
        let items = order.items.map {
            EcommerceItem(
                itemId: $0.product.id,
                itemName: $0.product.name,
                price: $0.product.price,
                quantity: $0.quantity
            )
        }
        
        AdStageManager.shared.trackEvent(
            AdStageEvent.Purchase(
                value: order.totalAmount,
                currency: "KRW",
                transactionId: order.id,
                items: items
            )
        )
        
        print("💰 Purchase: \(order.id)")
    }
    
    func trackError(_ error: Error, context: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Custom(
                params: [
                    "event_type": "error",
                    "error_message": error.localizedDescription,
                    "context": context
                ]
            )
        )
        print("❌ Error: \(context) - \(error)")
    }
}

5. Performance Optimization: Throttling

class ThrottledEventTracker {
    private var lastTrackTimes: [String: TimeInterval] = [:]
    private let throttleInterval: TimeInterval = 2.0  // 2 seconds
    
    func trackEvent(_ event: AdStageEventProtocol) {
        let eventKey = event.eventName
        let now = Date().timeIntervalSince1970
        let lastTime = lastTrackTimes[eventKey] ?? 0
        
        if now - lastTime >= throttleInterval {
            AdStageManager.shared.trackEvent(event)
            lastTrackTimes[eventKey] = now
        } else {
            print("⏱️ Throttled: \(eventKey)")
        }
    }
}
 
// Usage (scroll events, etc.)
let throttledTracker = ThrottledEventTracker()
 
func scrollViewDidScroll(_ scrollView: UIScrollView) {
    throttledTracker.trackEvent(
        AdStageEvent.Custom(
            params: [
                "action": "scroll",
                "offset_y": scrollView.contentOffset.y
            ]
        )
    )
}

Conversion Examples

// 1. Basic event
// OLD: EventTrackingManager.shared.trackEvent(...)
// NEW:
AdStageManager.shared.trackEvent(AdStageEvent.FirstOpen())
 
// 2. Login
// NEW:
AdStageManager.shared.trackEvent(AdStageEvent.Login(method: .email))
 
// 3. Screen view
// NEW:
AdStageManager.shared.trackEvent(AdStageEvent.ScreenView(screenName: "home"))
 
// 4. Custom
// NEW:
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(params: ["action": "click"])
)

Troubleshooting

1. Compile Error: "currency parameter required"

Problem:

// ❌ Error
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(value: 9900.0)
)

Solution:

// ✅ Add currency (ISO 4217, 3-letter)
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        value: 9900.0,
        currency: "KRW"
    )
)

2. Xcode Auto-complete Not Working

Solution:

Clean Build Folder: Product → Clean Build Folder (⇧⌘K)
Delete Derived Data: ~/Library/Developer/Xcode/DerivedData
Reinstall Pods:

pod deintegrate
pod install

3. Currency Code Validation Error

// ❌ 2-letter code
AdStageEvent.Purchase(value: 100.0, currency: "KR")
// ValidationException: "Currency must be 3-letter ISO 4217 code"
 
// ✅ 3-letter ISO 4217 code
AdStageEvent.Purchase(value: 100.0, currency: "KRW")  // Korean Won
AdStageEvent.Purchase(value: 100.0, currency: "USD")  // US Dollar
AdStageEvent.Purchase(value: 100.0, currency: "JPY")  // Japanese Yen

4. SwiftUI Preview Crash

Problem: AdStageManager initialization error in Preview

Solution:

#if DEBUG
struct ProductDetailView_Previews: PreviewProvider {
    static var previews: some View {
        ProductDetailView(productId: "PROD_123")
            .onAppear {
                // Don't initialize in Preview
                if ProcessInfo.processInfo.environment["XCODE_RUNNING_FOR_PREVIEWS"] == nil {
                    AdStageManager.shared.initialize(
                        apiKey: "test-key",
                        serverUrl: "https://api.adstage.app"
                    )
                }
            }
    }
}
#endif

5. Check Debug Logs

// AppDelegate.swift
func application(...) -> Bool {
    #if DEBUG
    AdStageManager.shared.setDebugMode(true)
    #endif
    
    AdStageManager.shared.initialize(...)
    return true
}

Console Filter:

# Xcode Console
filter: AdStage
