Question

I am creating a sample app for in app purchase. I have implemented for one product I used the following code in which I can implement the for one product purchasing, but if suppose there are more than one product then how can I get the list of all the identifiers for all the products available. Hope I am clear with the question.

I have used the following code for for one product as below.

- (void)viewDidLoad {
[super viewDidLoad];


if ([SKPaymentQueue canMakePayments]) {
        NSLog(@"Parental-controls are disabled");

        SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"com.companion.onemonth"]];
        productsRequest.delegate = self;
        [productsRequest start];
    } else {
        NSLog(@"Parental-controls are enabled");
        //com.companion.onemonth ;
    }
}


    - (IBAction)purchase {
    SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.companion.onemonth"];
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

Through this code I can get for one product but dont know how to get multiple identifiers at run time.

Answer 1

Put all your defined products hardcoded into the NSSet of SKProductsRequest:

[NSSet setWithObjecta:@"com.companion.onemonth", @"com.companion.twomonth"], nil)

and you you get an NSArray of available products in the delegate method:

(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response;

SKProductsResponse will have an array of your products.
