问题：

 

 

解决：

1. xcode target 属性启用 In-app purchase
2. 在itunesConnect 后台app 功能下添加 内购产品，记住填写的商品id； 添加测试用户（可选）
3. 在代码中使用 商品id获取SKProduct
   
   Swift

   req = SKProductsRequest(productIdentifiers: Set([**商品id**])) req.delegate = self req.start()

   1 2 3

   req = SKProductsRequest(productIdentifiers: Set([**商品id**]))             req.delegate = self             req.start()

   
    
4. 获取到SKProduct 后 会回调
   
   func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) { let pay = SKMutablePayment(product: response.products[0])//todo pay.quantity = 1 SKPaymentQueue.default().add(pay) }

   1 2 3 4 5

   func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {                 let pay = SKMutablePayment(product: response.products[0])//todo                 pay.quantity = 1                 SKPaymentQueue.default().add(pay)   }

   
    
5. 购买有结果后会回调
   
   /* 需要组成 transaction observer 才会调用下边的函数 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { .... SKPaymentQueue.default().add(self) .... } */ func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) { for t in transactions { if t.transactionState == .purchased { //unlock function queue.finishTransaction(t) } else if t.transactionState == .restored { //unlock function queue.restoreCompletedTransactions() } } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

   /* 需要组成 transaction observer 才会调用下边的函数     func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { ....         SKPaymentQueue.default().add(self) ....     } */     func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {         for t in transactions {                 if t.transactionState == .purchased { //unlock function                     queue.finishTransaction(t)                 } else if t.transactionState == .restored { //unlock function                     queue.restoreCompletedTransactions()                 }         }     }

   
    
6. 退出iphone 上app store 的登录账号，进入app 购买流程，输入账号时使用步骤2中添加的测试账号测试购买（切换成正式账号就能把测试账号踢掉）
7. 必须有恢复购买功能，恢复购买时需要调用
   
   Swift

   SKPaymentQueue.default().restoreCompletedTransactions()

   1	SKPaymentQueue.default().restoreCompletedTransactions()
