尝试使用其中一个StoreKit常量时,我收到错误“使用未解析的标识符”:
SKErrorClientInvalid SKErrorPaymentCancelled SKErrorPaymentInvalid SKErrorPaymentNotAllowed SKErrorStoreProductNotAvailable SKErrorUnknown
您的代码可能如下所示:
if transaction.error!.code == SKErrorPaymentCancelled { print("Transaction Cancelled: \(transaction.error!.localizedDescription)") }
改变了什么?我需要导入一个新模块吗?
解决方法
从iOS 9.3开始,某些StoreKit常量已从SDK中删除.有关更改的完整列表,请参见
StoreKit Changes for Swift.
这些常量已被替换为SKErrorCode
枚举和相关值:
SKErrorCode.ClientInvalid SKErrorCode.CloudServiceNetworkConnectionFailed SKErrorCode.CloudServicePermissionDenied SKErrorCode.PaymentCancelled SKErrorCode.PaymentInvalid SKErrorCode.PaymentNotAllowed SKErrorCode.StoreProductNotAvailable SKErrorCode.Unknown
您应该检查使用枚举的rawValue检查您的transaction.error.code.例:
private func FailedTransaction(transaction: SKPaymentTransaction) { print("FailedTransaction...") if transaction.error?.code == SKErrorCode.PaymentCancelled.rawValue { print("Transaction Cancelled: \(transaction.error?.localizedDescription)") } else { print("Transaction Error: \(transaction.error?.localizedDescription)") } SKPaymentQueue.defaultQueue().finishTransaction(transaction) }
