将Paypal SDK与本机iOS应用程序集成

Question

I am referring and integrating PayPal-iOS-SDK with my native iOS app.

I have successfully integrated the app(this is what I feel )

Please refer the code

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        PayPalMobile .initializeWithClientIdsForEnvironments([PayPalEnvironmentProduction: "YOUR_CLIENT_ID_FOR_PRODUCTION",
            PayPalEnvironmentSandbox: "SANDBOX CODE"])
        return true
    }

View Controller

//
//  ViewController.swift
//  PaypalDemo
//

import UIKit

class ViewController: UIViewController,PayPalPaymentDelegate  {

    var environment:String = PayPalEnvironmentNoNetwork {
        willSet(newEnvironment) {
            if (newEnvironment != environment) {
                PayPalMobile.preconnectWithEnvironment(newEnvironment)
            }
        }
    }



    #if HAS_CARDIO
    // You should use the PayPal-iOS-SDK+card-Sample-App target to enable this setting.
    // For your apps, you will need to link to the libCardIO and dependent libraries. Please read the README.md
    // for more details.
    var acceptCreditCards: Bool = true {
    didSet {
    payPalConfig.acceptCreditCards = acceptCreditCards
    }
    }
    #else
    var acceptCreditCards: Bool = false {
        didSet {
            payPalConfig.acceptCreditCards = acceptCreditCards
        }
    }

    func showSuccess(inputString: NSObject) {

        print("this is done successfully :) ")
        print("send this to server \(inputString)")
    }



}

My concerns regarding the app is

1.Whatever login I am using I am able to login . I have tried tim@cook.com as email and 1234 as password, still I was able to login.

2.I have tried using credit card as 4242-4242-4242-4242, cvv 123 12/12 and still payment was successful.

3.These are responses I am getting [client: { environment = mock; "paypal_sdk_version" = "2.14.3"; platform = iOS; "product_name" = "PayPal iOS SDK"; }, response_type: payment, response: { "create_time" = "2016-08-01T09:16:40Z"; id = "PAY-NONETWORKPAYIDEXAMPLE123"; intent = sale; state = approved; }] [client: { environment = mock; "paypal_sdk_version" = "2.14.3"; platform = iOS; "product_name" = "PayPal iOS SDK"; }, response_type: payment, response: { "create_time" = "2016-08-01T09:16:40Z"; id = "PAY-NONETWORKPAYIDEXAMPLE123"; intent = sale; state = approved; }] [client: { environment = mock; "paypal_sdk_version" = "2.14.3"; platform = iOS; "product_name" = "PayPal iOS SDK"; }, response_type: payment, response: { "create_time" = "2016-08-01T09:16:40Z"; id = "PAY-NONETWORKPAYIDEXAMPLE123"; intent = sale; state = approved; }] for another, { client = { environment = mock; "paypal_sdk_version" = "2.14.3"; platform = iOS; "product_name" = "PayPal iOS SDK"; }; response = { "create_time" = "2016-08-01T09:59:31Z"; id = "API-PAYMENT-ID-1843"; intent = sale; state = approved; }; "response_type" = payment; } { client = { environment = mock; "paypal_sdk_version" = "2.14.3"; platform = iOS; "product_name" = "PayPal iOS SDK"; }; response = { "create_time" = "2016-08-01T09:59:31Z"; id = "API-PAYMENT-ID-1843"; intent = sale; state = approved; }; "response_type" = payment; }

4. Is the integration successful, or is there something that I am missing, because in response from paypal I don't find unique order id, not amount that has been charged from the user.

EDIT 1 This is info I am getting from

print("this is also info (completedPayment.description)") from

func payPalPaymentViewController(paymentViewController: PayPalPaymentViewController, didCompletePayment completedPayment: PayPalPayment) 
`CurrencyCode: AUD

Amount: 216.46

Short Description: My Shop

Intent: sale

Processable: Already processed

Display: $216.46

Confirmation: {

    client =     {

        environment = mock;

        "paypal_sdk_version" = "2.14.3";

        platform = iOS;

        "product_name" = "PayPal iOS SDK";

    };

    response =     {

        "create_time" = "2016-08-01T11:05:51Z";

        id = "PAY-NONETWORKPAYIDEXAMPLE123";

        intent = sale;

        state = approved;

    };

    "response_type" = payment;

}

Details: Subtotal: 207.97, Shipping: 5.99, Tax: 2.5

Shipping Address: (null)

Invoice Number: (null)

Custom: (null)

Soft Descriptor: (null)

BN code: (null)

Item: '{2|Old jeans with holes|84.99|USD|Hip-0037}'

Item: '{1|Free rainbow patch|0.00|USD|Hip-00066}'

Item: '{1|Long-sleeve plaid shirt (mustache not included)|37.99|USD|Hip-00291}'`

Please correct, me where I am lacking.

Answer 1

If you go through below code

var environment:String = PayPalEnvironmentNoNetwork {
        willSet(newEnvironment) {
            if (newEnvironment != environment) {
                PayPalMobile.preconnectWithEnvironment(newEnvironment)
            }
        }
    }

Which is no network environment it will give you all the time success.

You need to change environment as per your requirement. For eg If you have sandbox user registered on PayPal then you need to change like this

 var environment:String = PayPalEnvironmentSandbox
        {
        willSet(newEnvironment) {
            if (newEnvironment != environment)
            {
                PayPalMobile.preconnectWithEnvironment(newEnvironment)
            }
        }
    }

And then if you try with any other user rather than registered sandbox user it will give you error. This will work for only sandbox user.

There is one more environment called Production which is for live purpose that you need to ask credentials from your client.

 PayPalEnvironmentProduction 

I hope the above information is clear which you was looking for.

• Don't forget to change client IDs in AppDelegate as per your respective environment

PayPalMobile.initializeWithClientIdsForEnvironments([PayPalEnvironmentProduction: "", PayPalEnvironmentSandbox: "AYP......"])
