SKProductsRequest返回0个产品的原因是什么？ [英] Reasons for SKProductsRequest returning 0 products?

问题描述

我正在尝试设置IAP，但在使用SKProductsRequest调用检索产品后，我的委托中的SKProductsResponse数组的计数为0.这是我的核对清单：

• 测试产品已添加到iTunes连接中


• 产品的包ID与应用包ID相匹配（并且不使用通配符）


• SKProductRequest中设置的产品标识符与iTunes连接上创建的产品相匹配


• 自iTunes产品在iTunes连接上创建以来，我等了好几个小时


• 供应配置文件启用IAP


• 按照各种教程中的所有步骤操作，例如
  2）iTunes Connect - >协议，税务和银行业务 - >主协议 - >付费应用程序 - >联系信息/银行信息/税务信息（应填写）
  3）测试代码
  

    class ViewController：UIViewController {
   
   var requestProd = SKProductsRequest（）
   var products = [SKProduct]（）
   
   override func viewDidLoad（）{ 
   super.viewDidLoad（）
   
   validateProductIdentifiers（）
  } 
  } 
   
  扩展名ViewController：SKProductsRequestDelegate {
   
   func validateProductIdentifiers（ ）{
   let productsRequest = SKProductsRequest（productIdentifiers：Set（[candy100，someOtherProductId]））
   
   //保持对请求的强引用。 
   self.requestProd = productsRequest; 
   productsRequest.delegate = self 
   productsRequest.start（）
  } 
   
   // SKProductsRequestDelegate协议方法
   public func productsRequest（_ request：SKProductsRequest，didReceive响应：SKProductsResponse）{
   
   self.products = response.products 
   
   for response.invalidProductIdentifiers {
   print（invalidIdentifier）
  } 
   
  } 
  } 
    

  
  

  I'm trying to set up IAP but after making a call to retrieve the products using SKProductsRequest the SKProductsResponse array within my delegate has a count of 0. Here's my checklist:

  • Test product has been added to iTunes connect
  • The product's bundle id matches the app bundle id (and its not using a wildcard)
  • The product identifier set in the SKProductRequest matches the product created on iTunes connect
  • I've waited several hours since the product was created on iTunes connect
  • The provisioning profiles enable IAP
  • Followed all steps in various tutorial such as http://troybrant.net/blog/2010/01/in-app-purchases-a-full-walkthrough/ etc.
  • Have deleted app from device, relaunched Xcode, rebuilt etc. etc.

  Any other suggestions as to why the fetched product count is zero?

  I don't believe this will be a coding issue, but here it is anyway:

  …
  
          NSSet *productIdentifiers = [NSSet setWithObjects:@"redacted", nil];
          self.productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
          self.productsRequest.delegate = self;
          [self.productsRequest start];
  
  …
  - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
  {
      NSArray *products = response.products;
      NSLog(@"Product count: %d", [products count]);
      for (SKProduct *product in products)
      {
          NSLog(@"Product: %@ %@ %f", product.productIdentifier, product.localizedTitle, product.price.floatValue);
      }
  }
  

  解决方案

  Check all 3 things in the list below
  1) check your product identifiers - they must be exactly the same that you have in your code and in iTunes Connect -> My Apps -> YourAppName -> Features -> In-App Purchases 2) iTunes Connect -> Agreements, Tax, and Banking -> Master Agreements -> Paid Applications-> Contact Info / Bank Info / Tax Info (should be filled) 3) code to test it
  

  class ViewController: UIViewController {
  
      var requestProd = SKProductsRequest()
      var products = [SKProduct]()
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          validateProductIdentifiers()
      }
  }
  
  extension ViewController: SKProductsRequestDelegate {
  
      func validateProductIdentifiers() {
          let productsRequest = SKProductsRequest(productIdentifiers: Set(["candy100", "someOtherProductId"]))
  
          // Keep a strong reference to the request.
          self.requestProd = productsRequest;
          productsRequest.delegate = self
          productsRequest.start()
      }
  
      // SKProductsRequestDelegate protocol method
      public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
  
          self.products = response.products
  
          for invalidIdentifier in response.invalidProductIdentifiers {
              print(invalidIdentifier)
          }
  
      }
  }
