我的 VC 是这样的:

var coins = 50 // coins
override func viewDidLoad() {
    super.viewDidLoad()
    if(SKPaymentQueue.canMakePayments()) {
        //print("enabled, loading")
        let productID: NSSet = NSSet(objects: "com.tahabuyruk.taha.coinsal", "com.tahabuyruk.taha.reklam") // my products Id
        let request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set)
        request.delegate = self
        request.start()
    } khác {
        print("please enable IAPS")
    }
}

//I have 2 products on itunesconnect

@IBAction func btnRemoveAds(_ sender: Any) {

    SKPaymentQueue.default().add(pay as SKPayment)

    lblAd.removeFromSuperview()

    coins += 50
    lblCoinAmount.text = "\(coins)"

我处理这个问题，查找协议(protocol)、税务和银行业务，并检查您的银行业务、联系方式和税务信息是否已填写

关于ios - 应用内购买错误，始终 myProduct 为 0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44205857/
