用户购买商品后,通过输入电子邮件和密码并付款,从不调用updatedTransactions方法。该项目是定期购买的,但没有调用updatedTransactions方法我不能执行代码将项目添加到应用程序。我注意到该商品已被购买,因为如果我运行代码来恢复购买的商品,一切都会顺利进行,并且产品会安装到应用中。
以下是我为购买该产品而复制的代码:
-(IBAction)buyProduct:(id)sender {
NSLog(@"Purchasing: %@", self.product.productIdentifier);
SKPayment *payment = [SKPayment paymentWithProduct:self.product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
按照代码恢复产品:
-(IBAction)restoreProduct:(id)sender {
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
我注意到在最后一段代码中我有以下几行:
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
我是否应该在购买部分添加此行?
答案 0 :(得分:1)
我通过在buyProduct方法中添加以下代码解决了这个问题:
-(IBAction)buyProduct:(id)sender {
NSLog(@"Purchasing: %@", self.product.productIdentifier);
SKPayment *payment = [SKPayment paymentWithProduct:self.product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self]; //added line
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
现在,在付款之前和付款之后调用updatedTransactions方法。
使用以下代码,您可以检查一切是好还是坏:
for(SKPaymentTransaction *transaction in transactions) {
if (transaction.transactionState == SKPaymentTransactionStatePurchased) {
[self unlockRemoveiAD];
[OKalertView show];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
if (transaction.transactionState == SKPaymentTransactionStateFailed) {
[alertView show];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
}
