我建立了一个应用内购买项目。以下是部分源代码:
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
NSLog(@"paymentQueue update");
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(@"completeTransaction");
// Your application should implement these two methods.
[self recordTransaction: transaction];
[self provideContent: transaction.payment.productIdentifier];
// Remove the transaction from the payment queue.
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
NSLog(@"restoreTransaction");
[self recordTransaction: transaction];
[self provideContent: transaction.originalTransaction.payment.productIdentifier];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
- (void) failedTransaction: (SKPaymentTransaction *)transaction
{
NSLog(@"failedTransaction");
if (transaction.error.code != SKErrorPaymentCancelled)
{
// Optionally, display an error here.
}
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
//Optional, record the transaction infomation
- (void) recordTransaction: (SKPaymentTransaction *)transaction{
receipt=transaction.transactionReceipt;
[[NSUserDefaults standardUserDefaults] setValue:transaction.transactionReceipt forKey:@"proUpgradeTransactionReceipt" ];
[[NSUserDefaults standardUserDefaults] synchronize];
[self sendReceipt:receipt];
expiredTime=transaction.transactionDate;
}
我可以在沙箱中成功添加付款并进行购买,
但是在执行
finishTransaction:
之后,完成的事务不会从defaultQueue中删除。添加付款时,defaultQueue会累积。
我会犯错吗?
感谢您的帮助。
最佳答案
真的是我的错
每次购买时,我都会复制Store Observer对象
在添加防止重复的标志后(如下所示),该错误已修复。
static bool hasAddObserver=NO;
-(void) recvPurchase:(NSString *)purchaseString{
//check user's in-app purchase status
if ([self CanPurchase]) {
/*=====================================*/
if (!hasAddObserver) {//flag to fix this bug
/*=====================================*/
observer=[[StoreObserver alloc]init];
[[SKPaymentQueue defaultQueue] addTransactionObserver:observer];
hasAddObserver=YES;
}
SKPayment *payment = [SKPayment paymentWithProductIdentifier:purchaseString];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
}
关于objective-c - finishTransaction:不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/5906204/
