【英文标题】：Setup Paypal client ID for credentials IOS SDK 2.1.6

【发布时间】：2014-09-30 13:57:12

【问题描述】：

我在我的应用中使用 Paypal SDK。我将我的环境设置为 PayPalEnvironmentSandbox，但是当我运行我的应用程序时，会出现一条警报，提示“与 Paypal 服务器通信时出现问题。请重试”。我用谷歌搜索了很多次，其他人说我需要更改客户端 ID，但我不知道如何更改客户端 ID，我在 paypal 的沙盒上有一个测试帐户，但我不知道如何在我的应用程序中实现它们。我阅读了文档，他们说我需要更改可能的客户 ID，但我不知道如何。需要你们的帮助，谢谢。我正在使用 ios paypal SDK 2.1.6。

代码：

#import "ZZMainViewController.h"
#import <QuartzCore/QuartzCore.h>
#import "PayPalMobile.h"

// Set the environment:
// - For live charges, use PayPalEnvironmentProduction (default).
// - To use the PayPal sandbox, use PayPalEnvironmentSandbox.
// - For testing, use PayPalEnvironmentNoNetwork.
//#define kPayPalEnvironment PayPalEnvironmentNoNetwork
#define kPayPalEnvironment PayPalEnvironmentSandbox

@interface ZZMainViewController ()

@property(nonatomic, strong, readwrite) IBOutlet UIButton *payNowButton;
@property(nonatomic, strong, readwrite) IBOutlet UIButton *payFutureButton;
@property(nonatomic, strong, readwrite) IBOutlet UIView *successView;

@property(nonatomic, strong, readwrite) PayPalConfiguration *payPalConfig;

  // Setting the languageOrLocale property is optional.
  //
  // If you do not set languageOrLocale, then the PayPalPaymentViewController will present
  // its user interface according to the device's current language setting.
  //
  // Setting languageOrLocale to a particular language (e.g., @"es" for Spanish) or
  // locale (e.g., @"es_MX" for Mexican Spanish) forces the PayPalPaymentViewController
  // to use that language/locale.

【参考方案1】：

要获得 client_id，您需要在 https://developer.paypal.com/webapps/developer/applications/myapps 注册并创建一个应用程序。然后，您将获得沙盒（和实时）凭据。

【讨论】：

我已经完成了那个先生，但是我不知道如何在应用程序中更改 client_id。

【参考方案2】：

这里是来自 PayPal 的戴夫。

要设置您的客户端 ID（一个用于 Sandbox，一个用于 Live），请参阅我们的Sample Code 中的第 1 步：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

    // ...
    [PayPalMobile initializeWithClientIdsForEnvironments:@PayPalEnvironmentProduction : @"YOUR_CLIENT_ID_FOR_PRODUCTION",
                                                     PayPalEnvironmentSandbox : @"YOUR_CLIENT_ID_FOR_SANDBOX"];
  // ...
    return YES;

【讨论】：

谢谢你，我会试试这个:)

@dave 我们计划使用新的 paypal ios sdk 来处理诸如用户会为他的问题的一些答案付费的东西，即用户提出了问题，如果有人会回答这个问题，我们会通过应用程序支付一些钱。付款将通过调解员进行，即我们将从用户那里拿钱，然后将钱转给回答的人，这会通过 APPLE 审核流程吗？你能进一步帮助我吗？

@AniShroff 我很乐意帮助解决涉及我们的 PayPal iOS SDK 的技术问题。但我无法就 Apple 的应用审核流程向您提供建议。

@DaveGoldman 有没有办法就此事获得建议？我已经尝试搜索网络，但无法获得任何详细信息。

@Dave 我可以在 paypal 处理付款之前获取交易密钥吗？

【参考方案3】：

您必须在 appdelegate.m 文件中进行更改。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary      *)launchOptions  #warning "Enter your credentials"
  [PayPalMobile initializeWithClientIdsForEnvironments:@PayPalEnvironmentProduction :    @"YOUR_CLIENT_ID_FOR_PRODUCTION",
  PayPalEnvironmentSandbox : @"ATIXyxAAjtL8-HdqfLq0kTCeefUi1SNI_xkfWktHelloqznRxsrm_Hello"]; return YES;

【参考方案4】：

用于 Swift 开发

    [PayPalMobile initializeWithClientIdsForEnvironments:@PayPalEnvironmentProduction                             :@"YOUR_CLIENT_ID_FOR_PRODUCTION",
      PayPalEnvironmentSandbox : @"ATIXyxAAjtL8-HdqfLq0kTCeefUi1SNI_xkfWktHelloqznRxsrm_Hello"];

你需要做的不会工作

 PayPalMobile.initializeWithClientIdsForEnvironments([PayPalEnvironmentProduction: "ID1", PayPalEnvironmentSandbox: "ID2"])
