Overview

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

Key Features

Global context management: Set user/device information once and it is automatically included
Simple API: Send events easily with just an event name and parameters
Automatic session tracking: Session IDs are generated and managed automatically
Asynchronous processing: Network communication does not block the UI
Offline support: Automatic resend when the network recovers

Basic Setup

CocoaPods Setup

Podfile

platform :ios, '15.0'
 
target 'YourApp' do
  use_frameworks!
  
  # AdStage SDK
  pod 'AdapterAdStage', '3.0.11'
end
 
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '15.0'
    end
  end
end

Install:

pod install

2. SDK Initialization

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

3. Info.plist Setup

<!-- 네트워크 사용 권한 -->
<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <false/>
</dict>

Type-Safe Event Sending

1. The Simplest Approach

import AdapterAdStage
 
// 파라미터 없는 이벤트
AdStageManager.shared.trackEvent(AdStageEvent.FirstOpen())
 
// 로그인 이벤트
AdStageManager.shared.trackEvent(
    AdStageEvent.Login(method: .email)
)

2. Purchase Event (Validation Example)

// ✅ GOOD: value와 currency 함께 제공
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        value: 29.99,
        currency: "USD",
        transactionId: "TXN_123456"
    )
)
 
// ❌ BAD: value만 제공 시 컴파일 에러!
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        value: 29.99  // ❌ 에러: currency 필수!
    )
)
 
// ✅ GOOD: currency 없이 transactionId만
AdStageManager.shared.trackEvent(
    AdStageEvent.Purchase(
        transactionId: "TXN_123456"
    )
)

3. Product View

// 파라미터와 함께
AdStageManager.shared.trackEvent(
    AdStageEvent.ProductDetailsView(
        itemId: "PROD_123",
        itemName: "Wireless Earbuds"
    )
)
 
// 파라미터 없이
AdStageManager.shared.trackEvent(AdStageEvent.ProductListView())

4. Custom Event (event_name Auto-Promotion)

To send app-specific events beyond the standard events, use AdStageEvent.Custom. If you include an event_name key in the parameters, that value is automatically promoted to the actual event name and stored in the dashboard.

// 예: 'promotion_click'이라는 커스텀 이벤트 전송
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(
        params: [
            "event_name": "promotion_click",
            "promotion_id": "summer_sale_2025",
            "screen": "home_banner"
        ]
    )
)
// 대시보드에는 "promotion_click" 이벤트로 수집됨
 
// event_name 없이 일반 커스텀 이벤트
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(
        params: [
            "action": "button_click",
            "button_id": "promo_banner",
            "screen": "home",
            "timestamp": Date().timeIntervalSince1970
        ]
    )
)
// 대시보드에는 "custom" 이벤트로 수집됨
 
// Click, View도 자유 파라미터 지원
AdStageManager.shared.trackEvent(
    AdStageEvent.Click(
        params: [
            "campaign_id": "SUMMER2025",
            "ad_group": "electronics"
        ]
    )
)

Standard Event Catalog

The AdStage SDK provides 46 standard events.

📌 Ad Tracking (4)

// 2. 광고 노출
AdStageManager.shared.trackEvent(
    AdStageEvent.View(
        params: ["impression_id": "IMP_456"]
    )
)
 
// 3. 앱 설치
AdStageManager.shared.trackEvent(AdStageEvent.Install())
 
// 4. 커스텀 이벤트 (event_name으로 이벤트 이름 지정)
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(
        params: [
            "event_name": "promotion_click",

    func applicationDidEnterBackground(_ application: UIApplication) {
        print("📱 앱 백그라운드 진입")

    }
    
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        trackScreenView()

            AdStageEvent.ScreenView(
                screenName: screenName,
                screenClass: String(describing: type(of: self))
            )
        )
        
        print("📺 \(screenName)")
    }
}
 
// 사용 예제
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
        // 데이터 로딩...
        
        // 상품 상세 조회 이벤트
        AdStageManager.shared.trackEvent(
            AdStageEvent.ProductDetailsView(
                itemId: productId,

                value: order.totalAmount,
                currency: "KRW",
                transactionId: order.id,
                tax: order.tax,
                shipping: order.shippingFee,
                coupon: order.couponCode,
                items: items
            )
        )
        
        print("✅ 구매 완료: \(order.id), \(order.totalAmount)원")
    }
    
    // 10. 환불
    func trackRefund(order: Order) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Refund(
                transactionId: order.id,
                value: order.totalAmount,
                currency: "KRW"
            )
        )
    }
    
    // 11. 공유
    func trackShare(product: Product, method: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Share(
                contentType: "product",
                method: method
            )
        )
    }
}

5. Game Events

class GameEventManager {
    
    // 튜토리얼
    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)
                ]
            )
        )
    }
    
    // 레벨
    func trackLevelUp(level: Int, character: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.LevelUp(
                level: level,
                character: character
            )
        )
    }
    
    // 업적
    func trackAchievement(achievementId: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.Achievement(achievementId: achievementId)
        )
    }
    
    // 게임 플레이
    func trackGameStart(level: Int, levelName: String, character: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.GamePlay(
                level: level,
                levelName: levelName,
                character: character,
                contentType: "pvp"
            )
        )
    }
    
    // 보너스 획득
    func trackBonusAcquired(itemId: String, itemName: String, quantity: Int) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.AcquireBonus(
                contentType: "reward",
                itemId: itemId,
                itemName: itemName,
                quantity: quantity
            )
        )
    }
    
    // 가상 화폐(크레딧) 획득 - AcquireBonus 사용
    func trackEarnCurrency(currencyName: String, amount: Int) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.AcquireBonus(
                contentType: "currency",
                itemName: currencyName,
                quantity: amount
            )
        )
    }
    
    // 가상 화폐(크레딧) 사용 - SpendCredits 사용
    func trackSpendCurrency(currencyName: String, amount: Double, itemName: String) {
        AdStageManager.shared.trackEvent(
            AdStageEvent.SpendCredits(
                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))
            )
        )
    }
}
 
// 사용
class ProfileViewController: UIViewController {
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        trackScreen()  // ✅ 간단!
    }
}

2. Tracking Events in a ViewModel

class ProductViewModel: ObservableObject {
    
    @Published var product: Product?
    
    func loadProduct(productId: String) {
        Task {
            do {
                let product = try await repository.getProduct(productId)
                self.product = product
                
                // 상품 조회 이벤트
                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 in SwiftUI

import SwiftUI
import AdapterAdStage
 
struct ProductDetailView: View {
    let productId: String
    @StateObject private var viewModel = ProductViewModel()
    
    var body: some View {
        VStack {
            // UI...
            
            Button("장바구니에 추가") {
                viewModel.addToCart(viewModel.product, quantity: 1)
                
                // 버튼 클릭 이벤트
                AdStageManager.shared.trackEvent(
                    AdStageEvent.Custom(
                        params: [
                            "action": "add_to_cart_button",
                            "product_id": productId
                        ]
                    )
                )
            }
        }
        .onAppear {
            viewModel.loadProduct(productId: productId)
            
            // 화면 조회 이벤트
            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  // 2초
    
    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)")
        }
    }
}
 
// 사용 (스크롤 이벤트 등)
let throttledTracker = ThrottledEventTracker()
 
func scrollViewDidScroll(_ scrollView: UIScrollView) {
    throttledTracker.trackEvent(
        AdStageEvent.Custom(
            params: [
                "action": "scroll",
                "offset_y": scrollView.contentOffset.y
            ]
        )
    )
}

Conversion Example

// 1. 기본 이벤트
// OLD: EventTrackingManager.shared.trackEvent(...)
// NEW:
AdStageManager.shared.trackEvent(AdStageEvent.FirstOpen())
 
// 2. 로그인
// NEW:
AdStageManager.shared.trackEvent(AdStageEvent.Login(method: .email))
 
// 3. 화면 조회
// NEW:
AdStageManager.shared.trackEvent(AdStageEvent.ScreenView(screenName: "home"))
 
// 4. 커스텀
// NEW:
AdStageManager.shared.trackEvent(
    AdStageEvent.Custom(params: ["action": "click"])
)

Troubleshooting

1. Compile Error: "currency parameter required"

Problem:

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

Solution:

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

2. Xcode Autocomplete 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

// ❌ 2자리 코드
AdStageEvent.Purchase(value: 100.0, currency: "KR")
// ValidationException: "Currency must be 3-letter ISO 4217 code"
 
// ✅ 3자리 ISO 4217 코드
AdStageEvent.Purchase(value: 100.0, currency: "KRW")  // 한국 원
AdStageEvent.Purchase(value: 100.0, currency: "USD")  // 미국 달러
AdStageEvent.Purchase(value: 100.0, currency: "JPY")  // 일본 엔

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 {
                // Preview에서는 초기화하지 않음
                if ProcessInfo.processInfo.environment["XCODE_RUNNING_FOR_PREVIEWS"] == nil {
                    AdStageManager.shared.initialize(
                        apiKey: "test-key",
                        serverUrl: "https://api.adstage.app"
                    )
                }
            }
    }
}
#endif

5. Checking Debug Logs

The SDK automatically prints logs of the initialization and event-sending process to the console. You can check them directly in the Xcode console without any separate debug mode setup.

Console filter:

# Xcode Console
filter: AdStage   (또는 ADSTAGE)

Q: Can I use it in SwiftUI?
A: Yes, it is fully supported through the ObservableObject pattern.
