Question

我建立了一个应用内购买，它工作正常然后我创建了一个新的目标c类，并将所有编码应用于新类中好的，现在我想从我的主视图控制器调用应用内购买。这怎么可能？谢谢

viewcontroller.m

- (void)viewDidLoad
{
    InAppPurchaseManager *IAPmanager = [[InAppPurchaseManager alloc]init];
    if([SKPaymentQueue canMakePayments])
        {
            //sets payment observer to class.
            [[SKPaymentQueue defaultQueue] addTransactionObserver:self];

            //initializes products array.
            products = [[NSMutableArray alloc]init];
            [IAPmanager loadStore];

        }
            else
            {
                NSLog(@"failed");
            }

}

InAppPurchaseManager.m

-(void)loadStore
{
    //restarts any purchases if they were interupted last time the was open
    [[SKPaymentQueue defaultQueue]addTransactionObserver:self];
    //get the product description
    ViewController *viewcontroller = [[ViewController alloc]init];
    [viewcontroller requestProductData];
}
//request product
-(void)requestProductData
{
    NSSet *productIdentifiers = [NSSet setWithObjects:@"com.company.myApp.App1",nil ];
    SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
    productsRequest.delegate = self;
    [productsRequest start];
    NSLog(@"product request start");

}

它在此之前停止运行

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    myproducts = response.products;
    for(proUpgradeProduct in myproducts)
    {
        //debug log.
        NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
        NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
        NSLog(@"Product price: %@" , proUpgradeProduct.price);
        NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
    }
    // invalid purchase
    for (NSString *invalidProductId in response.invalidProductIdentifiers)
    {
        NSLog(@"Invalid product id: %@" , invalidProductId);
    }

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

    NSLog(@"receive respond");
}

从您想要的任何课程调用此方法 -

- （IBAction）购买：（id）发件人 {

InAppPurchaseManager * inapp = [[InAppPurchaseManager alloc] init];

[inapp loadStore];

if ([inapp canMakePurchases]) {
    [inapp purchaseProUpgrade];

} }

InAppPurchase来自另一个nsobject
