Question

购买成功后，我想执行segue。但是无论如何，我的代码不起作用。 devam（）函数是必须执行segue的函数。但即使如此。购买。该功能不起作用。我知道购买成功，但是没有采取措施。

对于交易中的aTransact {

        switch aTransact.transactionState {

        case .deferred:
            print(aTransact.payment.productIdentifier,"beklemede")
            break
        case .failed:
            queue.finishTransaction(aTransact)
            print(aTransact.payment.productIdentifier,"başarısız")
            break
        case .purchased:
            devam()
            print(aTransact.payment.productIdentifier,"Tamamlandı")
            break
        case .purchasing:
            print(aTransact.payment.productIdentifier,"Alım İşlemi Başladı")
            break
        case .restored:
            queue.finishTransaction(aTransact)
            print(aTransact.payment.productIdentifier,"önceki alım yenilendi")
            break
        default:break


        }

    }

func devam（）{

        let board : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

        let tabBar = board.instantiateViewController(withIdentifier: "tabBar") as! ViewControllerSat2

        window?.rootViewController = tabBar



    }

Answer 1

似乎window是nil，所以做到

(UIApplication.shared.delegate as! AppDelegate).window!.rootViewController = tabBar

购买成功后，相关功能不起作用
