我在我的应用程序中使用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，会发出警告说＃34;与Paypal服务器通信时出现问题。请再试一次＆＃34;。我google了很多次，其他说我需要更改clientId但我不知道如何更改客户端ID，我在paypal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，他们说我需要更改客户端ID类似的东西，但我不知道如何。需要你帮助的人谢谢你。我使用的是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

戴夫来自PayPal。
要设置客户端ID（一个用于Sandbox，一个用于Live），请参阅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;
}

对于Swift开发
[PayPalMobile initializeWithClientIdsForEnvironments:@{PayPalEnvironmentProduction :@"YOUR_CLIENT_ID_FOR_PRODUCTION",
PayPalEnvironmentSandbox : @"ATIXyxAAjtL8-HdqfLq0kTCeefUi1SNI_xkfWktHelloqznRxsrm_Hello"}];
无论你需要做什么工作
PayPalMobile.initializeWithClientIdsForEnvironments([PayPalEnvironmentProduction: "ID1", PayPalEnvironmentSandbox: "ID2"])
答案 2 :(得分：0)
要获得client_id，您需要注册＆amp;在https://developer.paypal.com/webapps/developer/applications/myapps创建应用。然后，您将获得沙盒（和实时）凭据。
答案 3 :(得分：0)
你必须在appdelegate.m文件中更改。
- (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;}
