How to get locale currency price for in-app purchases in iOS?

Question

I want to find out user's App Store location. It means they are in US, Australia(AUD) store. Following code used.

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    Books = response.products;
    if ([SKPaymentQueue canMakePayments] && [response.products count]>0) {

    }

    for (SKProduct *book in Books) {
        NSLocale *locat=[NSLocale currentLocale];
        NSString *strlocate=[locat objectForKey:NSLocaleCountryCode];

        NSLog(@"\n\n\n Device country== %@ \n\n\n",strlocate);

        NSLocale* storeLocale = book.priceLocale;
        NSString *storeCountry = (NSString*)CFLocaleGetValue((CFLocaleRef)storeLocale, kCFLocaleCountryCode);
        NSLog(@"\n\n\n store country== %@ \n\n\n",storeCountry);
    }
}

I want like wise if book tier is one means US $ 0.99 AUD 0.99 JPY 85 based on the app store price matrix table.

I tested in the simulator. I changed country name in iTunes, appstore and safari application in the system. but I get only US country code.

Edit: Settings-> General-> International->Region Format-> country

I tested in the device: Device country only changed. store country show US country code and price. I want to store country code before start inapp purchase time.

how many days once change the price for based on currency fluctuation? is it provide any api/ query for fluctuated price to known/update?

my inapp operation made one class. Before inapp operation made i want to display the local price to user same price effect reflect in the inapp operation.

i display the list of book free and paid books thats is list get from my server. in that i display the price for each item. those item price while processing the appstore it will show the dollar price. if appstore shown the price as also i want to shown. so that i want to send country code to my server from that my server respond that country related price list and currency symbol..

Answer 1

productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:prodcutIdentifier];
    productsRequest.delegate = self;
    
    // This will trigger the SKProductsRequestDelegate callbacks
    [productsRequest start];

This will call your delegate function. Once the above is done, it will automatically call the below mentioned function finally. This is where the app store request sent will be finalized.

(void)requestDidFinish:(SKRequest *)request
{
   
    
    SKProduct *book = [Books objectAtIndex:0];
        
    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
    [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
    [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
    [numberFormatter setLocale:book.priceLocale];
    
    NSLocale* storeLocale = book.priceLocale;
    NSString *storeCountry = (NSString*)CFLocaleGetValue((CFLocaleRef)storeLocale, kCFLocaleCountryCode);
    
}

provide the Locale and country details as per your interest.
