这段代码的重点是使用名为 MobileAppTracking 的服务跟踪购买，其中一些被正确跟踪。但是该服务显示此代码正在发送一堆额外的购买电话，iTunes Connect 中没有记录。以下大部分只是来自典型 IOS storekit 的样板代码。具体来说，此代码来自 InAppPurchaseManager，这是一个用于 IOS 购买的 IOS 插件。
这是我正在使用的插件： https ://github.com/phonegap/phonegap-plugins/tree/master/iPhone/InAppPurchaseManager
这是我修改后的代码：
// SKPaymentTransactionObserver methods
// called when the transaction status is updated
//
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
NSString *state, *error, *transactionIdentifier, *transactionReceipt, *productId;
NSInteger errorCode;
SKPayment *thePayment;
for (SKPaymentTransaction *transaction in transactions)
{
error = state = transactionIdentifier = transactionReceipt = productId = @"";
errorCode = 0;
BOOL shouldTrackEvent = false; // maybe this should just be for successful purchases.
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchasing:
continue;
case SKPaymentTransactionStatePurchased:
state = @"PaymentTransactionStatePurchased";
transactionIdentifier = transaction.transactionIdentifier;
transactionReceipt = [[transaction transactionReceipt] base64EncodedString];
productId = transaction.payment.productIdentifier;
//thePayment = transaction.payment;
//NSLog(@"localCurr=", thePayment.currency );
//NSLog(@"localCurr=", thePayment.localizedTitle );
shouldTrackEvent = true;
break;
case SKPaymentTransactionStateFailed:
state = @"PaymentTransactionStateFailed";
error = transaction.error.localizedDescription;
errorCode = transaction.error.code;
NSLog(@"error %d %@", errorCode, error);
break;
case SKPaymentTransactionStateRestored:
state = @"PaymentTransactionStateRestored";
transactionIdentifier = transaction.originalTransaction.transactionIdentifier;
transactionReceipt = [[transaction transactionReceipt] base64EncodedString];
productId = transaction.originalTransaction.payment.productIdentifier;
break;

continue;
