So do i need to display the prices localized which is fetched from my-server? please let me know how should i proceed?

Thanks a lot for stopping by..

Yes, you should show localized prices.

From App Store Quick Reference: Getting Started with In-App Purchase on iOS and OS X Lion:

Since your application may be available in App Stores with a region specific currency and
language, your item’s localized description and pricing information should be pulled from the
App Store via StoreKit’s products request API. You’ll use the information returned from the
products request to populate the user interface you present to the customer for item selection
and purchase

The product request API from StoreKit is pretty straightforward, it returns a ProductResponse, which contains an SKProduct, which includes both the price and the priceLocale. Per the SKProduct Class Reference, your code to format the price in the current local should be something like:

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[numberFormatter setLocale:product.priceLocale];
NSString *formattedString = [numberFormatter stringFromNumber:product.price];
