SKProductsRequest - 现在没有响应（正在工作 - 相同的代码）

Question

代码如下 - 昨天工作的代码提供了无效的 ID，现在工作时间更长了，我已经浏览了大约 10 次代码

。m

 #import <UIKit/UIKit.h>
 #import <StoreKit/StoreKit.h>

@interface InAppViewController : UIViewController  <SKProductsRequestDelegate, SKPaymentTransactionObserver> {

    SKProduct *proUpgradeProduct;
    SKProductsRequest *productsRequest;
}

.h

#import "InAppViewController.h"


@implementation InAppViewController

- (void)viewDidLoad{
    [self requestProUpgradeProductData];
}

- (void)dealloc {
    [super dealloc];
}

- (void)requestProUpgradeProductData
{
    NSLog(@"called  productsRequest");

    NSSet *productIdentifiers = [NSSet setWithObject:@"com.okz8.investor.gem15" ];
    productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
    productsRequest.delegate = self;
    [productsRequest start];

    // we will release the request object in the delegate callback
}

#pragma mark -
#pragma mark SKProductsRequestDelegate methods

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray *products = response.products;
    proUpgradeProduct = [products count] == 1 ? [[products firstObject] retain] : nil;
    if (proUpgradeProduct)
    {
        NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
        NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
        NSLog(@"Product price: %@" , proUpgradeProduct.price);
        NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
    }

    for (NSString *invalidProductId in response.invalidProductIdentifiers)
    {
        NSLog(@"Invalid product id: %@" , invalidProductId);
    }

    // finally release the reqest we alloc/init’ed in requestProUpgradeProductData
    [productsRequest release];

    //[[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerProductsFetchedNotification object:self userInfo:nil];
}

这只是不返回响应，我已经在这里完成了所有操作 http://troybrant.net/blog/2010/01/invalid-product-ids/

之前收到的 ID 无效，现在我什么也没收到

Answer 1

遇到了同样的问题，并在这里找到了解决方案：
productsRequest 响应方法未调用

由于自动引用计数，我的请求被立即删除再次...

Answer 2

根据 user178379 的响应，尝试实现此方法：

- (void)request:(SKRequest *)request didFailWithError:(NSError *)error {
    NSLog(@"request - didFailWithError: %@", [[error userInfo] objectForKey:@"NSLocalizedDescription"]);
}

我的问题是：无法连接到 iTunes Store，其用途是：

StoreKit (In-App purchases) will not work in the Simulator. 13962338

Answer 3

我刚刚在 iOS 15 设备上遇到了这个问题。

- (void)request:(SKRequest *)request didFailWithError:(NSError *)error

也已实现，但也未调用。

重新启动设备，一切又恢复正常了！

当发生这种情况时，我会在日志中得到以下内容或类似内容：

[BackgroundTask] Background Task 6 ("SKProductsRequest"), was created over 30 seconds ago. In applications running in the background, this creates a risk of termination. Remember to call UIApplication.endBackgroundTask(_:) for your task in a timely manner to avoid this.

Answer 4

顺便说一句，在这种情况下，当构建 SKProductsRequest 期间传递的产品标识符集为空时，SKProductsRequestDelegate 委托函数都不是叫。
