我遇到了严重的问题我正在努力购买应用程序,当我第一次尝试购买它工作正常,第二次我的completeTransaction调用了两次.. 我不知道为什么我会遇到这个问题。
我收到收据后,我打电话给我的验证方法,如果验证没问题,服务器会在http响应中发送音频文件,我下载文件,当我成功下载文件时,我会调用finishtransaction。
这是我的代码
- (void)startPurchase {
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
if([SKPaymentQueue canMakePayments]) {
NSLog(@"IN-APP:can make payments");
SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObject:myIdentifier]];
request.delegate = self;
NSLog(@"** Productdata is ** %@",myIdentifier);
[request start];
}
else {
NSLog(@"IN-APP:can't make payments");
loadingHUD.hidden=YES;
}
}
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
NSLog(@"IN productsRequest END %d",[response.products count]);
@try {
SKProduct *product = [response.products objectAtIndex:0];
SKPayment *newPayment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:newPayment];
NSLog(@"IN-APP:productsRequest END");
loadingHUD.hidden=YES; // Hide the Loading progress bar
}
@catch (NSException *exception) {
// Failed to purchase Hide the progress bar and Display Error Dialog
loadingHUD.hidden=YES;
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"error" message:@"Errror " delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions)
{
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchased:
[self completeTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];
default:
break;
}
}
}
- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
NSLog(@"Transaction Completed");
// Finally, remove the transaction from the payment queue.
[self verifyReceipt:transaction]; // Call the verifyReceipt method to send transaction.bytes
// [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
NSLog(@"Purchase Transaction finish");
}
在下载成功块中的VerifyTransaction方法中,我调用完成事务
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
[[SKPaymentQueue defaultQueue] finishTransaction: transaction]; // Finish the transaction
// NSLog(@"Successfully downloaded file to %@",[[NSString alloc] initWithData:operation.responseData encoding:NSASCIIStringEncoding]);
// Give alert that downloading successful.
NSLog(@"Successfully downloaded file to %@", destPath);
// NSLog(@"response: %@", operation.responseString); // Give alert that downloading successful.
// [self.target parserDidDownloadItem:destPath];
//loadingHUD.detailsLabelText = [NSString stringWithFormat:@"%@ %i%%",@"Downloading",100];
[loadingHUD hide:TRUE];
[DBHelper savePurchaseId:fileName]; // save the purchase itune id into local database to populate hover image of play button on main List
[self movieReceived];
}

看起来您的Observer队列仍然包含较旧的产品ID
- (void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray *)transactions
{
NSLog(@"Purchase removedTransactions");
// Release the transaction observer since transaction is finished/removed.
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
}
完成交易后删除产品ID。

我最终做了以下事情:
if(contains(self.transactions, trans.transactionIdentifier) == false) {
self.transactions.append(trans.transactionIdentifier)
//Give the user the purchased product
}
删除观察员有点缓解了这个问题,但是当我发现垃圾邮件时,我仍然偶尔会有双重通话。#34;应用中的购买按钮。上面的解决方案完全解决了它,在我的测试中似乎非常强大。
