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

I want the buttons that you have to tap to buy something to show the price of that.

For example: "5 coins €0,99"

But if I create a UIlabel with exactly that text, Americans will also see the price in € instead of usd.

Now how can I set the price where it adjust to the currency the user lives in? I saw it on some games so I am convinced that this is possible.

thank you!

You might want to to localize (internationalize) your interface and texts.

In order to do that you'll have look how to do it for :

  • Your storyboard (you'll still handle one, but translate the texts you want in an inside file)
  • Inside your code. Through NSLocalizedString see for example Apple or NSHipster, ...

If purchases are done via Apple App Store (using StoreKit framework) you need to get price + currency from SKProduct object (prices will vary).

https://developer.apple.com/library/ios/documentation/StoreKit/Reference/SKProduct_Reference/

Update

  1. you need to perform request to load available products
var productID:NSSet = NSSet(object: “product_id_on_itunes_connect”);
var productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID);
productsRequest.delegate = self;
productsRequest.start();
  1. Request delegate will return SKProduct.
func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
    println("got the request from Apple")
    var validProducts = response.products
    if !validProducts.isEmpty {
        var validProduct: SKProduct = response.products[0] as SKProduct
        if (validProduct.productIdentifier == self.product_id) {
            println(validProduct.localizedTitle)
            println(validProduct.localizedDescription)
            println(validProduct.price)
            buyProduct(validProduct);
        } else {
            println(validProduct.productIdentifier)
        }
    } else {
        println("nothing")
    }
}
  1. SKProduct contains all needed information to display localized price, but I suggest to create SKProduct category that formats price + currency to user current locale
import StoreKit

extension SKProduct {

    func localizedPrice() -> String {
        let formatter = NSNumberFormatter()
        formatter.numberStyle = .CurrencyStyle
        formatter.locale = self.priceLocale
        return formatter.stringFromNumber(self.price)!
    }

}

Information taken from here and here.

Swift 4

import StoreKit

extension SKProduct {
    var localizedPrice: String {
        let formatter = NumberFormatter()
        formatter.numberStyle = .currency
        formatter.locale = priceLocale
        return formatter.string(from: price)!
    }
}
