36. Auto-renewable Subscription
• Newsstand App requires at least one Auto-renewable
subscription or free subscription
• Auto-renewable durations are: 7d, 1m, 2m, 3m, 6m, 1y
• StoreKit won’t let app know duration from product
identifier
• Need to query to your server or hard-coded
37. Restore Problem
• What if Someone purchased auto-renewable
subscriptions in-and-out few times
• Purchased records can be retrieved by restore operation
• But it can be cancelled, and StoreKit wouldn’t tell me...
• Needs to ask to Apple’s server to verify those purchases
