ios - 清除 SKPAymentQueue : Forcing Unfinished Transactions To Finish

Question

我的付款队列中仍然有一些恢复交易 - 因为当我测试有缺陷的恢复购买操作时，一旦交易恢复，我从未调用 finishTransaction。

根据一些在线研究，我意识到我必须手动强制完成付款队列中未完成的交易。

有人在 Objective-C 中发布了这段代码:

// take current payment queue
SKPaymentQueue* currentQueue = [SKPaymentQueue defaultQueue];
// finish ALL transactions in queue
[currentQueue.transactions enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
[currentQueue finishTransaction:(SKPaymentTransaction *)obj];
}];

我不知道如何将它转换为 Swift 2.0。

谁能帮我做这个？谢谢:-)

这是一个 for 循环，它将遍历每个待处理的交易并检查状态，并完成购买失败或成功的交易。

let currentQueue : SKPaymentQueue = SKPaymentQueue.default();
        for transaction in currentQueue.transactions {
            if (transaction.transactionState == SKPaymentTransactionState.failed) {
                //possibly handle the error
                currentQueue.finishTransaction(transaction);
            } else if (transaction.transactionState == SKPaymentTransactionState.purchased) {
                //deliver the content to the user
                currentQueue.finishTransaction(transaction);
            } else {
                //handle other transaction states
            }
        }
