问题描述

限时删除!!

我想要购买商品时必须点击的按钮来显示商品的价格.

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

例如:5 个硬币 0.99 欧元"

For example: "5 coins €0,99"

但如果我创建一个 UIlabel 与该文本完全一致,美国人也会看到以欧元而不是美元为单位的价格.

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

现在我如何设置价格以适应用户居住的货币?我在一些游戏中看到过,所以我相信这是可能的.

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.

谢谢!

推荐答案

如果购买是通过 Apple App Store(使用 StoreKit 框架)完成的,您需要从 SKProduct 对象中获取价格 + 货币(价格会有所不同).

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

更新

  1. 您需要执行加载可用产品的请求
var productID:NSSet = NSSet(object: "product_id_on_itunes_connect");
var productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID);
productsRequest.delegate = self;
productsRequest.start();
  1. 请求 delegate 将返回 SKProduct.
  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 包含显示本地化价格所需的所有信息,但我建议创建 SKProduct 类别,将价格 + 货币格式设置为用户当前语言环境
import StoreKit

extension SKProduct {

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

}

取自此处此处.

import StoreKit

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