在swift中获取用户的App购买价格

Price of in-app purchases shown on screen(with currency)

在

import StoreKit

extension SKProduct {

        func localizedPrice() -> String {
            let formatter = NSnumberFormatter()
            formatter.numberStyle = .CurrencyStyle
            formatter.locale = self.priceLocale
            return formatter.StringFromnumber(self.pricE)!
        }

    }

要么

您可以获得最新的收据信息

IAPs actually validating the receipt (Swift)

if let receipTinfo: NSArray = parseJSON["latest_receipt_info"] as? NSArray {
                       let lastReceipt = receipTinfo.lastObject as! NSDictionary

                        // Get last receipt
                        println("LAST RECEIPT INFORMATION \n",lastReceipt)
}
