iOS SDK'da Flow & Paywall Builder ile satın almaları etkinleştirme

SwiftUI’da flow’u görüntülerken olayları da yönetmeniz gerekir. didFinishPurchase, didFailPurchase, didFinishRestore, didFailRestore ve didReceiveError zorunludur. Test sırasında bu olayları günlüğe kaydetmek için aşağıdaki kod parçacığını olduğu gibi kopyalayabilirsiniz.

.flow(
    isPresented: $flowPresented,
    flowConfiguration: flowConfiguration,
    didFinishPurchase: { product, purchaseResult in
        print("Purchase finished successfully")
        flowPresented = false // or do nothing to let the flow continue
    },
    didFailPurchase: { product, error in
        print("Purchase failed: \(error)")
    },
    didFinishRestore: { profile in
        print("Restore finished successfully")
    },
    didFailRestore: { error in
        print("Restore failed: \(error)")
    },
    didReceiveError: { error in
        flowPresented = false
        print("Flow error: \(error)")
    }
)

func presentFlow(with config: AdaptyUI.FlowConfiguration) {
    let flowController = try AdaptyUI.flowController(
        with: config,
        delegate: self
    )
    present(flowController, animated: true)
}

AdaptyFlowControllerDelegate arayüzünü uygulayarak olayları yönetin. En azından varsayılan uygulaması olmayan dört metodu implemente edin. Controller, başarılı bir satın alma sonrasında kendini otomatik olarak kapatmaz — didFinishPurchase içinde kapatın ya da flow’un sonraki ekranlarına devam etmesi için hiçbir şey yapmayın:

extension YourViewController: AdaptyFlowControllerDelegate {
    func flowController(_ controller: AdaptyFlowController,
                        didFinishPurchase product: AdaptyPaywallProduct,
                        purchaseResult: AdaptyPurchaseResult) {
        if !purchaseResult.isPurchaseCancelled {
            controller.dismiss(animated: true) // or do nothing to let the flow continue
        }
    }

    func flowController(_ controller: AdaptyFlowController,
                        didFailPurchase product: AdaptyPaywallProduct,
                        error: AdaptyError) {
        print("Purchase failed: \(error)")
    }

    func flowController(_ controller: AdaptyFlowController,
                        didFinishRestoreWith profile: AdaptyProfile) {
        print("Restore finished successfully")
    }

    func flowController(_ controller: AdaptyFlowController,
                        didFailRestoreWith error: AdaptyError) {
        print("Restore failed: \(error)")
    }
}

.flow(
    isPresented: $flowPresented,
    flowConfiguration: flowConfiguration,
    didPerformAction: { action in
        switch action {
            case .close:
                flowPresented = false // dismiss the flow when the user taps close
            default:
                break
        }
    },
    didFinishPurchase: { product, purchaseResult in flowPresented = false },
    didFailPurchase: { product, error in /* handle the error */ },
    didFinishRestore: { profile in /* check access level and dismiss */ },
    didFailRestore: { error in /* handle the error */ },
    didReceiveError: { error in flowPresented = false }
