Transparencias de la charla en NSCoder night Madrid el 7 de Marzo de 2018: "Cómo tener analíticas en tu app y no volverte loco"

1. Cómo tener analíticas en
tu app y no volverte loco
Gemma del Olmo

2. Quién soy
• Desarrollando iOS desde iOS 5
• iOS developer en ApeLucy: La app que te da
megas
• @gmmx919

3. Agenda
• El problema.
• La solución.
• Experiencia personal con diferentes herramientas
de Analytics.

4. EL PROBLEMA
Con algo de código y muchos gifs :)

5. El problema
• Necesitan integrar GoogleAnalytics

7. Vamos a ello
• pod ‘Google/Analytics’
• pod Install

8. AppDelegate
import Google
func application(application: UIApplication, didFinishLaunchingWithOptions
launchOptions: [NSObject: AnyObject]?)
-> Bool {
..
self.setupGoogleAnalytics()
..
}
func setupGoogleAnalytics() {
// Configure tracker from GoogleService-Info.plist.
let configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services:
(configureError)")
let gai = GAI.sharedInstance()
gai.trackUncaughtExceptions = true // report uncaught exceptions
gai.logger.logLevel = GAILogLevel.Verbose // remove before app release
}

9. Enviar eventos
@IBAction func login(sender: AnyObject) {
var tracker = GAI.sharedInstance().defaultTracker
tracker.send(GAIDictionaryBuilder.createEventWithCategory("Button",
action: "Login", label: nil, value: nil).build() as [NSObject :
AnyObject])
}

11. El problema
• Necesitan integrar GoogleAnalytics
• 1 semana más tarde…

12. El problema
• Necesitan integrar GoogleAnalytics
• 1 semana más tarde… Necesitan integrar eventos de
Fabric

14. Vamos a ello
• pod ‘Fabric’
• pod ‘Answers’
• pod Install

15. AppDelegate
import Google
import Fabric
import Answers
func application(application: UIApplication, didFinishLaunchingWithOptions
launchOptions: [NSObject: AnyObject]?)
-> Bool {
..
setupGoogleAnalytics()
setupFabricAnalytics()
..
}
func setupGoogleAnalytics() {
// Configure tracker from GoogleService-Info.plist.
let configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services:
(configureError)")
let gai = GAI.sharedInstance()
gai.trackUncaughtExceptions = true // report uncaught exceptions
gai.logger.logLevel = GAILogLevel.Verbose // remove before app release
}
func setupFabricAnalytics() {
Fabric.with([Answers.self])
}

16. Enviar eventos
@IBAction func login(sender: AnyObject) {
var tracker = GAI.sharedInstance().defaultTracker
tracker.send(GAIDictionaryBuilder.createEventWithCategory("Button",
action: "Login", label: nil, value: nil).build() as [NSObject : AnyObject])
Answers.logCustomEvent(withName: "Login", customAttributes: nil)
}

18. El problema
• Necesitan integrar GoogleAnalytics
• 1 semana más tarde… Necesitan integrar eventos de
Fabric
• 1 mes más tarde…

19. El problema
• Necesitan integrar GoogleAnalytics
• 1 semana más tarde… Necesitan integrar eventos de
Fabric
• 1 mes más tarde… Quieren integrar Amplitude

21. LA SOLUCIÓN

22. Partes en común de
los SDK de analytics
• Inicializar en
applicationDidFinishLaunchingWithOp
tions
• Enviar eventos en el controller

23. AnalyticsService
protocol AnalyticsService {
func initialize(application: UIApplication, launchOptions:
[UIApplicationLaunchOptionsKey: Any]?)
func track(event: AnalyticsEvent)
}

24. Qué es un evento
enum AnalyticsEvent {
case login
case levelUp(level: Int)
case signUp
case updateProfile
}

25. Qué es un evento
extension AnalyticsEvent {
var name: String {
switch self {
case .login:
return "Login"
case .levelUp(_):
return "Level Up"
case .signUp:
return "Signup"
case .updateProfile:
return "Update Profile"
}
}
var metadata: [String: String] {
switch self {
case .levelUp(let level):
return ["level": String(level)]
default:
return [:]
}
}
}

26. AnalyticsService - Fabric
class FabricAnalyticsService: AnalyticsService {
func initialize(application: UIApplication, launchOptions:
[UIApplicationLaunchOptionsKey : Any]?) {
Fabric.with([Crashlytics.self])
}
func track(event: AnalyticsEvent) {
Answers.logCustomEvent(withName: event.name, customAttributes:
event.metadata)
}
}

27. Lo que nuestros
controllers conocerán
• Eventos
• AnalyticsManager

28. AnalyticsManager
class AnalyticsManager: AnalyticsService {
private var services: [AnalyticsService] = [FabricAnalyticsService(),
AmplitudeAnalyticsService()]
static let instance = AnalyticsManager()
private init() {}
func initialize(application: UIApplication, launchOptions:
[UIApplicationLaunchOptionsKey: Any]?) {
for service in services {
service.initialize(
application : application,
launchOptions : launchOptions
)
}
}
func track(event: AnalyticsEvent) {
for service in services {
service.track(event: event)
}
}
}

29. Let’s go!
func application(_ application: UIApplication, didFinishLaunchingWithOptions
launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
AnalyticsManager.instance.initialize(application: application,
launchOptions: launchOptions)
return true
}

30. Trackear eventos
@IBAction func loginTapped() {
analyticsManager.track(event: .login)
}
func userDidLevelUp() {
analyticsManager.track(event: .levelUp(level: 5))
}

31. Cómo encajo esto en
una arquitectura
class ViewControllerTracker {
let analytics: AnalyticsService
init(analyticsService: AnalyticsService = AnalyticsManager.instance) {
analytics = analyticsService
}
func userDidLogin() {
analytics.track(event: .login)
}
func userDidLevelUp(level: Int) {
analytics.track(event: .levelUp(level: level))
}
}

32. Trackear eventos
class ViewController: UIViewController {
let tracker: ViewControllerTracker = ViewControllerTracker()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//MARK: - IBActions
@IBAction func loginTapped() {
tracker.userDidLogin()
}
@IBAction func levelUpTapped() {
tracker.userDidLevelUp(level: 5)
}
}

33. EXTRA: Qué herramienta de
analytics uso actualmente y por
qué
• Google Analytics
• Fabric
• Firebase
• Amplitude
