我正在尝试为我的应用程序创建一个商店页面，以便用户可以购买硬币或其他任何东西，但是当我尝试获取项目列表时，它似乎没有显示。它打印“产品请求”但不打印该项目。这些项目出现在 itunes 连接页面中，我使用了相同的 ID，所以我很确定我的代码有问题。
class storeController : UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver {
var list = [SKProduct]()
var p = SKProduct()
func buyProduct(){
print("buy \(p.productIdentifier)")
var pay = SKPayment(product: p)
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().addPayment(pay as SKPayment)
}
override func viewDidLoad() {
if(SKPaymentQueue.canMakePayments()) {
print("IAP is enabled, loading...")
var productID : NSSet = NSSet(object: "myapp.iap.500coins")
var request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>)
request.delegate = self
request.start()
} else {
print("please enable IAPs")
}
}
func requestDidFinish(request: SKRequest) {
}
func request(request: SKRequest, didFailWithError error: NSError) {
}
func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
print("add payment")
for transactions:AnyObject in transactions {
var trans = transactions as! SKPaymentTransaction
print(trans.error)
switch trans.transactionState {
case .Purchased:
print("unlock iap here")
print(p.productIdentifier)
let prodID = p.productIdentifier as String
switch prodID {
case "myapp.iap.500coins" :
print("give coins")
default:
print("didnt go through")
}
queue.finishTransaction(trans)
break;
case .Failed:
print("error")
queue.finishTransaction(trans)
break;
default:
print("default")
}
}
}
func finishTransaction(trans:SKPaymentTransaction) {
print("finished trans")
}
func paymentQueue(queue: SKPaymentQueue, removedTransactions transactions: [SKPaymentTransaction]) {
print("remove trans")
}
func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
print("Product Request")
let myProduct = response.products
for product in myProduct {
print("product found")
print(product.productIdentifier)
print(product.localizedTitle)
print(product.localizedDescription)
list.append(product)
}
}
}
最佳答案
您的代码看起来不错。但是我怀疑您的产品标识符有问题。
SKProductsResponse 包含一系列未被 Apple App Store 识别的产品标识符。当一切顺利时，这个列表是空的。检查该列表以查看您的产品是否存在问题:
func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
if !response.invalidProductIdentifiers.isEmpty {
print("invalid:" + response.invalidProductIdentifiers)
}
print("Product Request")
let myProduct = response.products
...
}
这不会解决您的问题，但至少您会知道为什么您的回复中没有产品。
