18. iOS Bootcamp Case history • Clear App 350K download in 9 giorni a $0.99 l’uno ora il prezzo è a $2.99 • Draw Something +50M download in meno di 2 mesi.
19. iOS Bootcamp Riassumendo • Il contesto Un ambiente che invoglia l’utente • Credit card There are 400 million iTunes accounts (with credit cards attached and ready to spend)
20. quindi...
21. iOS Bootcamp Apps Trends 1. Games 2. Education 3. Entertainment 4. Books 5. Lifestyle http://148apps.biz/app-store-metrics/
22. http://pragmamark.org Environment
23. iOS Bootcamp Think different I contro del mondo Apple • nessun programma di certificazione per devs • unico evento la WWDC • politica di update Xcode & SDK • specifiche tecniche device non complete • risorse sotto NDA • Apple ID e ADP come se piovesse ^_^
24. iOS Bootcamp Think different I pro del mondo Apple • WWDC di qualità • risorse di qualità (soprattutto la docs) • strumenti curati e performanti (anche se...) • iOS SDK
25. iOS Bootcamp Requisiti • Mac OS • Xcode (free) • Device (iPhone/iPad/iPodTouch) • Apple ID • Apple Developer Program (ADP)
26. http://pragmamark.org Context Process Platforms Tools Mobile Market AppStore Environment Apple Developer Program Devices SDK Xcode Simulator Instruments Process Apple Developer Program
27. Developer Programs iOS Developer Program $99/year App Store / 100 device iOS Developer Enterprise Program $299/year NO App Store / ∞ device iOS Developer University Program free NO App Store / 200 person
28. iOS Bootcamp Apple Developer Program • Member Center gestione utenti, sottoscrizioni e rinnovi • iOS Provisioning Portal certificati di sviluppo e distribuzione, device • iTunes Connect app submission, sales and trends e pagamenti iOS Provisioning Portal
29. iOS Bootcamp Concepts • Certificati Identificano univocamente un attore • Devices Elenco dei device abilitati al testing • App IDs Identificativi univoci delle app • Provisioning E’ un asset che unisce i tre concetti precedenti
30. iOS Bootcamp Certificati • Development Certificate Associato ad una persona del team • Distribution Certificate Associato all’identità dell’azienda (sviluppatore)
31. iOS Bootcamp Devices • Scopo device per fini di sviluppo e test • Name + UDID Unique Device IDentifier, stringa di 40 caratteri es. 67a43b0925c7a8050ad788591ace81d1bda81bed • Limiti 1. ADP prevede un massimo di 100 device 2. Non è possibile eliminare un device fino al successivo rinnovo dell’ADP
32. iOS Bootcamp App IDs • Bundle Identifier è l’identificativo univoco dell’app • Reverse domain name es. com.mycompany.BestAppEver • Wild-card character es. com.mycompany.*
33. iOS Bootcamp Provisioning • Che cosa è è un una risorsa (un file) che unisce i 3 concetti precedenti ovvero App-ID, Devices e Certificati • A cosa serve è incluso nell’applicazione e serve per definire chi è autorizzato a distribuire l’app e chi è autorizzato ad eseguire l’app.
34. iOS Bootcamp Provisioning •Development Provisioning ‣ App ID ‣ elenco di certificati (development certificate) ‣ elenco di device •Distribution Provisioning ‣ Distribution method (App Store o AdHoc) ‣ App ID ‣ un certificato (distribution certificate) ‣ e in caso di AdHoc un elenco di device
