未解析的标识符 - SKErrorPaymentCancelled [英] Unresolved Identifier - SKErrorPaymentCancelled

问题描述

随着iOS 9.3及更新版本的发布，我更新到最新版本的Xcode 7.3 OSX 10.11.4（包括Swift 2.2）昨天。

I updated to the latest version of Xcode 7.3 with the release of iOS 9.3 & OSX 10.11.4 (inclusive of Swift 2.2) yesterday.

当我构建我的应用程序时，我收到一条错误，声明
使用未解决的标识符'SKErrorPaymentCancelled'我用它来检查用户是否取消了付款。我没有做任何特别的事情，只记录它（如下所示）。

When I build my app I get an error stating Use of unresolved identifier 'SKErrorPaymentCancelled' which I use to check if the user has cancelled a payment. I don't do anything special with it, just log it (as seen below).

private func failedTransaction(transaction: SKPaymentTransaction) {
    print("failedTransaction...")
    if transaction.error!.code == SKErrorPaymentCancelled {
        print("Transaction Cancelled: \(transaction.error!.localizedDescription)")
    }
    else {
        print("Transaction Error: \(transaction.error!.localizedDescription)")
    }
    SKPaymentQueue.defaultQueue().finishTransaction(transaction)
}

我在Swift 2.2更新日志中找不到任何内容说明StoreKit中的任何内容都已更改。这在我更新之前工作正常。

I can't find anything in the Swift 2.2 changelog that states anything within StoreKit was changed. This worked fine before I updated.

还有其他人看到这个问题吗？

Is anyone else seeing this issue?

推荐答案

从iOS 9.3开始，SDK中已删除常量 SKErrorPaymentCancelled 。相反，请使用 SKErrorCode.PaymentCancelled enum。

The constant SKErrorPaymentCancelled has been removed from the SDK as of iOS 9.3. Instead, use the SKErrorCode.PaymentCancelled enum.
