在购买应用程序时出现iTune问题！

Question

I am setting up an in-app-purchase system in my app. I have registered the in-app-purchase at iTune connect. And here comes my code:

This is the code for requesting product info:

- (void) requestProductData {   
    SKProductsRequest *request= 
        [[[SKProductsRequest alloc] initWithProductIdentifiers: 
         [NSSet setWithObject:@"com.myapp.id"]] autorelease];
    request.delegate = self;
    [request start];
}

This is the code for receiving the product info: (basically I did nothing but trying to print it out)

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
    NSArray *myProduct = response.products;
    SKProduct *product = [myProduct objectAtIndex:0];
    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
    [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
    [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
    [numberFormatter setLocale:product.priceLocale];
    NSString *formattedString = [numberFormatter stringFromNumber:product.price];
    [numberFormatter release];
    NSLog(@"Product 0 : %@, %@, %@, %@, %@", product.productIdentifier, product.localizedDescription, product.localizedTitle, product.priceLocale.localeIdentifier, formattedString);
    [request autorelease];
}

I have applied the delegate:

@interface StoreObserver : NSObject <SKProductsRequestDelegate>{

I used a button to trigger requestProductData . By using breakpoints, I was sure it got called. However, productsRequest was never called. I made sure of the connectivity too.

Does anybody hava any clue?

Answer 1

你跳过了我猜的部分方法

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

Answer 2

It turns out that the problem is here:

- (void) requestProductData {   
    SKProductsRequest *request= 
        [[[SKProductsRequest alloc] initWithProductIdentifiers: 
         [NSSet setWithObject:@"com.myapp.id"]] autorelease]; //<- here
    request.delegate = self;
    [request start];
}

You should never autorelease the SKProductsRequest. I am so stupid to make this mistake.
