应用程式内购买时应用程式崩溃 [英] App crashing when buying in-app purchase
本文介绍了应用程式内购买时应用程式崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
大多数情况下，它工作正常，但有时应用程序崩溃，没有任何错误（我正在测试
要设置应用内购买（非消费品），我使用以下示例：
https://github.com/conceptdev/xamarin-samples/tree/master/InAppPurchase/NonConsumables
处理应用内购买的类如下所示：
public class InAppPurchaseManager：SKProductsRequestDelegate {
public static NSString InAppPurchaseManagerProductsFetchedNotification = new NSString（InAppPurchaseManagerProductsFetchedNotification）;
public static NSString InAppPurchaseManagerTransactionFailedNotification = new NSString（InAppPurchaseManagerTransactionFailedNotification）;
public static NSString InAppPurchaseManagerTransactionSucceededNotification = new NSString（InAppPurchaseManagerTransactionSucceededNotification）;
public static NSString InAppPurchaseManagerRequestFailedNotification = new NSString（InAppPurchaseManagerRequestFailedNotification）;
SKProductsRequest productsRequest;
CustomPaymentObserver theObserver;
SKProduct []产品;
public static NSAction Done {get; set;}
public InAppPurchaseManager（）
{
theObserver = new CustomPaymentObserver（this）;
SKPaymentQueue.DefaultQueue.AddTransactionObserver（theObserver）;
}
//接收对RequestProductData的响应 - 包含价格，标题和描述信息
public override void ReceivedResponse（SKProductsRequest请求，SKProductsResponse响应）
{
products = response.Products;
NSDictionary userInfo = null;
if（products.Length> 0）{
NSObject [] productIdsArray = new NSObject [response.Products.Length];
NSObject [] productsArray = new NSObject [response.Products.Length];
for（int i = 0; i< response.Products.Length; i ++）{
productIdsArray [i] = new NSString（response.Products [i] .ProductIdentifier）;
productsArray [i] = response.Products [i];
}
userInfo = NSDictionary.FromObjectsAndKeys（productsArray，productIdsArray）;
}
NSNotificationCenter.DefaultCenter.PostNotificationName（InAppPurchaseManagerProductsFetchedNotification，this，userInfo）;
foreach（response.InvalidProducts中的string invalidProductId）{
Console.WriteLine（Invalid product id：+ invalidProductId）;
}
}
//一次请求多个产品
public void RequestProductData（List< string> productIds）
{
var array = new NSString [productIds.Count];
for（var i = 0; i< productIds.Count; i ++）{
array [i] = new NSString（productIds [i]）;
}
NSSet productIdentifiers = NSSet.MakeNSObjectSet< NSString>（array）;
//设置应用内购买的产品请求
productsRequest = new SKProductsRequest（productIdentifiers）;
productsRequest.Delegate = this; // SKProductsRequestDelegate.ReceivedResponse
productsRequest.Start（）;
Console.WriteLine（BEREIKT）;
}
//验证iTunes帐户是否可以为此应用程序进行此购买
public bool CanMakePayments（）
{
return SKPaymentQueue.CanMakePayments;
}
public void PurchaseProduct（string appStoreProductId）
{
Console.WriteLine（PurchaseProduct+ appStoreProductId）;
SKPayment payment = SKPayment.PaymentWithProduct（appStoreProductId）;
SKPaymentQueue.DefaultQueue.AddPayment（payment）;
}
public void CompleteTransaction（SKPaymentTransaction transaction）
{
Console.WriteLine（CompleteTransaction+ transaction.TransactionIdentifier）;
var productId = transaction.Payment.productIdentifier;
//注册购买，所以下次记住它
//PhotoFilterManager.Purchase(productId）;
UserDefaults.Purchase（productId）;
FinishTransaction（transaction，true）;
//显示对话框
new UIAlertView（Succes，De aankoop is gelukt。+
\\\
Je kunt de gekozencategorieënnu spelen。 ，OK，null）.Show（）;
/ *
if（ReceiptValidation.VerificationController.SharedInstance.VerifyPurchase（transaction））{
Console.WriteLine（Verified！
//注册购买，所以下次记住它
PhotoFilterManager.Purchase（productId）;
FinishTransaction（transaction，true）;
} else {
Console.WriteLine（NOT Verified :(）;
FinishTransaction（transaction，false）;
}
* /
}
public void RestoreTransaction（SKPaymentTransaction transaction）
{
//恢复的事务总是有一个'原始事务'
Console.WriteLine（RestoreTransaction+ transaction.TransactionIdentifier +;原始事务+ transaction.OriginalTransaction.TransactionIdentifier）;
var productId = transaction.OriginalTransaction.Payment.ProductIdentifier;
//注册购买，因此下次记住
// PhotoFilterManager。购买（productId）; //它就像是再次购买
UserDefaults.Purchase（productId）;
FinishTransaction（transaction，true）;
}
void FailedTransaction（SKPaymentTransaction transaction）
{
// SKErrorPaymentCancelled == 2
if（transaction.Error.Code == 2）//用户取消
Console.WriteLine CANCELLED FailedTransaction Code =+ transaction.Error.Code ++ transaction.Error.LocalizedDescription）;
else //错误！
Console.WriteLine（FailedTransaction Code =+ transaction.Error.Code ++ transaction.Error.LocalizedDescription）;
FinishTransaction（transaction，false）;
//显示对话框
new UIAlertView（Helaas，De aankoop is mislukt。+
\\\
Probeer het openen tijdstip nogmaals aub，null ，OK，null）.Show（）;
}
public void FinishTransaction（SKPaymentTransaction transaction，bool wasSuccessful）
{
Console.WriteLine（FinishTransaction+ wasSuccessful）;
//从支付队列中删除事务。
SKPaymentQueue.DefaultQueue.FinishTransaction（transaction）; //这是重要的 - 让苹果知道我们要完成！
using（var pool = new NSAutoreleasePool（））{
NSDictionary userInfo = NSDictionary.FromObjectsAndKeys（new NSObject [] {transaction}，new NSObject [] {new NSString（transaction） }）;
if（wasSuccessful）{
//发出一个通知我们完成了事务
NSNotificationCenter.DefaultCenter.PostNotificationName（InAppPurchaseManagerTransactionSucceededNotification，this，userInfo）;
} else {
//发送失败事务的通知
NSNotificationCenter.DefaultCenter.PostNotificationName（InAppPurchaseManagerTransactionFailedNotification，this，userInfo）;
}
}
}
///< summary>
///可能无法连接到App Store（网络不可用？）
///< / summary>
public override void RequestFailed（SKRequest request，NSError error）
{
Console.WriteLine（** InAppPurchaseManager RequestFailed（）+ error.LocalizedDescription）;
using（var pool = new NSAutoreleasePool（））{
NSDictionary userInfo = NSDictionary.FromObjectsAndKeys（new NSObject [] {error}，new NSObject [] {new NSString（error）}）;
//发送失败事务的通知
NSNotificationCenter.DefaultCenter.PostNotificationName（InAppPurchaseManagerRequestFailedNotification，this，userInfo）;
}
}
///< summary>
///恢复对此Apple ID发生的任何事务，无论是在
///此设备或使用该帐户登录的任何其他。
///< / summary>
public void Restore（）
{
Console.WriteLine（** InAppPurchaseManager Restore（））;
//将通知Observer恢复的事务何时开始到达< - AppStore
SKPaymentQueue.DefaultQueue.RestoreCompletedTransactions（）;
}
}
会导致崩溃的原因是什么？
FYI：我使用Xamarin iOS版本6.3.4.36（测试版）。现在我使用这个测试版，因为它解决了我与游戏中心的问题。 Xamarin的稳定版本并没有解决这个问题。
PS。我读了我使用的示例没有实现RECEIPT VERIFICATION。

第二次更新
我刚刚找到问题的发生方式。用于购买和恢复应用内购买的按钮以模态视图显示。似乎应用程序崩溃时，我重新打开模态视图，点击购买或恢复按钮。所以当我第一次打开模态视图，我点击购买和恢复按钮（大部分时间）工作正常。但是当我重新打开模态视图，我点击购买或恢复按钮，应用崩溃与上面的错误显示。
有人熟悉这个？ >
解决方案
问题解决了！
我在关闭视图时删除了TransactionObserver 。
public override void ViewWillDisappear（bool animated）
{
base.ViewWillDisappear
//重新打开视图时防止崩溃
SKPaymentQueue.DefaultQueue.RemoveTransactionObserver（theObserver）;
}
My app crashes sometimes when buying something with in-app purchase.
Most of the time it works fine but sometimes the app crashes without any error (I am testing in debug mode).
To set-up the in-app purchase (non-consumable), I used the following example: https://github.com/conceptdev/xamarin-samples/tree/master/InAppPurchase/NonConsumables
The class which handles the in-app purchase looks like this:
public class InAppPurchaseManager : SKProductsRequestDelegate {
public static NSString InAppPurchaseManagerProductsFetchedNotification = new NSString("InAppPurchaseManagerProductsFetchedNotification");
public static NSString InAppPurchaseManagerTransactionFailedNotification = new NSString("InAppPurchaseManagerTransactionFailedNotification");
public static NSString InAppPurchaseManagerTransactionSucceededNotification = new NSString("InAppPurchaseManagerTransactionSucceededNotification");
public static NSString InAppPurchaseManagerRequestFailedNotification = new NSString("InAppPurchaseManagerRequestFailedNotification");
SKProductsRequest productsRequest;
CustomPaymentObserver theObserver;
SKProduct[] products;
public static NSAction Done {get;set;}
public InAppPurchaseManager ()
{
theObserver = new CustomPaymentObserver(this);
SKPaymentQueue.DefaultQueue.AddTransactionObserver(theObserver);
}
// received response to RequestProductData - with price,title,description info
public override void ReceivedResponse (SKProductsRequest request, SKProductsResponse response)
{
products = response.Products;
NSDictionary userInfo = null;
if (products.Length > 0) {
NSObject[] productIdsArray = new NSObject[response.Products.Length];
NSObject[] productsArray = new NSObject[response.Products.Length];
for (int i = 0; i < response.Products.Length; i++) {
productIdsArray[i] = new NSString(response.Products[i].ProductIdentifier);
productsArray[i] = response.Products[i];
}
userInfo = NSDictionary.FromObjectsAndKeys (productsArray, productIdsArray);
}
NSNotificationCenter.DefaultCenter.PostNotificationName(InAppPurchaseManagerProductsFetchedNotification,this,userInfo);
foreach (string invalidProductId in response.InvalidProducts) {
Console.WriteLine("Invalid product id: " + invalidProductId );
}
}
// request multiple products at once
public void RequestProductData (List<string> productIds)
{
var array = new NSString[productIds.Count];
for (var i = 0; i < productIds.Count; i++) {
array[i] = new NSString(productIds[i]);
}
NSSet productIdentifiers = NSSet.MakeNSObjectSet<NSString>(array);
//set up product request for in-app purchase
productsRequest = new SKProductsRequest(productIdentifiers);
productsRequest.Delegate = this; // SKProductsRequestDelegate.ReceivedResponse
productsRequest.Start();
Console.WriteLine ("BEREIKT");
}
// Verify that the iTunes account can make this purchase for this application
public bool CanMakePayments()
{
return SKPaymentQueue.CanMakePayments;
}
public void PurchaseProduct(string appStoreProductId)
{
Console.WriteLine("PurchaseProduct " + appStoreProductId);
SKPayment payment = SKPayment.PaymentWithProduct (appStoreProductId);
SKPaymentQueue.DefaultQueue.AddPayment (payment);
}
public void CompleteTransaction (SKPaymentTransaction transaction)
{
Console.WriteLine ("CompleteTransaction " + transaction.TransactionIdentifier);
var productId = transaction.Payment.ProductIdentifier;
// Register the purchase, so it is remembered for next time
//PhotoFilterManager.Purchase(productId);
UserDefaults.Purchase(productId);
FinishTransaction (transaction, true);
//Show Dialog

/*
if (ReceiptValidation.VerificationController.SharedInstance.VerifyPurchase (transaction)) {
Console.WriteLine ("Verified!");
// Register the purchase, so it is remembered for next time
PhotoFilterManager.Purchase(productId);
FinishTransaction (transaction, true);
} else {
Console.WriteLine ("NOT Verified :(");
FinishTransaction (transaction, false);
}
*/
}
public void RestoreTransaction (SKPaymentTransaction transaction)
{
// Restored Transactions always have an 'original transaction' attached
Console.WriteLine("RestoreTransaction " + transaction.TransactionIdentifier + "; OriginalTransaction " + transaction.OriginalTransaction.TransactionIdentifier);
var productId = transaction.OriginalTransaction.Payment.ProductIdentifier;
// Register the purchase, so it is remembered for next time
//PhotoFilterManager.Purchase(productId); // it's as though it was purchased again
UserDefaults.Purchase(productId);
FinishTransaction(transaction, true);
}
public void FailedTransaction (SKPaymentTransaction transaction)
{
//SKErrorPaymentCancelled == 2
if (transaction.Error.Code == 2) // user cancelled
Console.WriteLine("User CANCELLED FailedTransaction Code=" + transaction.Error.Code + " " + transaction.Error.LocalizedDescription);
else // error!

}
public void FinishTransaction(SKPaymentTransaction transaction, bool wasSuccessful)
{
Console.WriteLine("FinishTransaction " + wasSuccessful);
// remove the transaction from the payment queue.
SKPaymentQueue.DefaultQueue.FinishTransaction(transaction); // THIS IS IMPORTANT - LET'S APPLE KNOW WE'RE DONE !!!!
using (var pool = new NSAutoreleasePool()) {
NSDictionary userInfo = NSDictionary.FromObjectsAndKeys(new NSObject[] {transaction},new NSObject[] {new NSString("transaction")});
if (wasSuccessful) {
// send out a notification that we’ve finished the transaction
NSNotificationCenter.DefaultCenter.PostNotificationName(InAppPurchaseManagerTransactionSucceededNotification,this,userInfo);
} else {
// send out a notification for the failed transaction
NSNotificationCenter.DefaultCenter.PostNotificationName(InAppPurchaseManagerTransactionFailedNotification,this,userInfo);
}
}
}
/// <summary>

public override void RequestFailed (SKRequest request, NSError error)

{
Console.WriteLine (" ** InAppPurchaseManager Restore()");
// theObserver will be notified of when the restored transactions start arriving <- AppStore
SKPaymentQueue.DefaultQueue.RestoreCompletedTransactions();
}
}
What could cause the crash?
FYI: I am using Xamarin iOS version 6.3.4.36 (beta). For now I use this beta version because it solves a problem I have with Game Center. The stable version of Xamarin does not solve this yet.
PS. I read that the example I used not implemented RECEIPT VERIFICATION. What does this mean and is this necessary to implement?
FIRST UPDATE:
Sometimes I get this error.

SECOND UPDATE
I just found the way the problem occurs. The buttons to buy and restore an in-app purchase are displayed in a modal view. It seems that the app crashes when I reopen the modal view and tap at the buy or restore button. So when I open the modal view for the first time and I tap at the buy and restore buttons it (most of the time) works fine. But when I reopen the modal view, and I tap at the buy or restore button, the app crashes with the error showed above.
Somebody familiar with this?
解决方案
Problem solved!
I had to remove the TransactionObserver when closing the view.
public override void ViewWillDisappear (bool animated)
{
base.ViewWillDisappear (animated);
//Prevents crash when re-opening view
SKPaymentQueue.DefaultQueue.RemoveTransactionObserver (theObserver);
}
