PayPaliOSSDK

[Swift3.0.2]PayPal iOSSDKの組み込み方

Posted by R on 2017-04-25

[環境]
Xcode:8.2.1
Swift:3.0.2
iOS:10.2

PayPaliOSSDKの組み込み・利用方法になります。
前提として、下図のように必要ファイルはプロジェクト内に組み込みが完了している必要があります。

単純に使える状態にする方法に焦点を絞り、
下図のようにボタンをタップしたらPayPal支払いに遷移するというシンプルなコードの紹介です。
（※ご自身の状況や環境に合わせてカスタマイズしてください。）

細かい説明は割愛し、コードを貼ります。
こんな感じです。

import UIKit

class TestPaymentViewController: UIViewController, PayPalPaymentDelegate {
    
    var payPalConfig = PayPalConfiguration()
    
    
     // Note: デフォルトは接続・通信が発生しないPayPalEnvironmentNoNetworkが設定されている
     // テスト環境への接続はPayPalEnvironmentSandboxを設定
     // 本番環境への接続はPayPalEnvironmentProductionを設定
    
    var environment:String = PayPalEnvironmentSandbox {
        willSet(newEnvironment) {
            if (newEnvironment != environment) {
                PayPalMobile.preconnect(withEnvironment: newEnvironment)
            }
        }
    }
    
    var acceptCreditCards: Bool = true {
        didSet {
            payPalConfig.acceptCreditCards = acceptCreditCards
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Set Up PayPalConfig
        payPalConfig.acceptCreditCards = acceptCreditCards //false

        payPalConfig.merchantUserAgreementURL = URL(string: "https://www.paypal.com/webapps/mpp/ua/useragreement-full")
        payPalConfig.languageOrLocale = Locale.preferredLanguages[0]

        // its user interface according to the device's current language setting.
        //
