我可以在 iPhone/iPad 应用程序中使用 PayPal 吗？

Question

我正在开发一个应用程序，我想通过它出售一些活动门票。

我可以使用 PayPal 来实现此目的吗？Apple 是否会批准使用其他 StoreKit 框架的应用程序。

我搜索了这个主题，但找不到任何可能的解决方案。

一些搜索称可以使用 paypal，另一些则称 Apple 从未批准使用除 inAppPurchase 之外的支付网关的应用程序。

请帮我！

Answer 1

是的，您可以在您的应用程序中使用 PayPal 支付网关。您可以从以下链接查看完整的文档：

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_documentation#mobile

在您的 .h 文件中添加以下代码

#import "PayPal.h"
#import "PayPalList.h"

typedef enum PaymentStatuses 
{
    PAYMENTSTATUS_SUCCESS,
    PAYMENTSTATUS_FAILED,
    PAYMENTSTATUS_CANCELED,
} PaymentStatus;

实现此委托方法“PayPalPaymentDelegate”

PayPalList *payPalList;
PaymentStatus status;

在您的 .m 文件中添加以下代码

#import "PayPalPayment.h"
#import "PayPalAdvancedPayment.h"
#import "PayPalAmounts.h"
#import "PayPalReceiverAmounts.h"
#import "PayPalAddress.h"
#import "PayPalInvoiceItem.h"
#define SPACING 3.

    frame.origin.x = 60;

Answer 2

尽管 iPhone 中存在用于 Paypal 集成的 API，但根据 Apple 指南，它不会批准此类应用程序进入其 AppStore。
请参阅此处的 Apple 指南第 11.3 条 https://developer.apple.com/appstore/资源/批准/guidelines.html

Answer 3

嗯，我认为这取决于。

虽然我确信苹果不会允许除应用内购买之外的任何其他内容，但我确实知道德国应用商店中至少有一款应用程序，它允许您在应用程序内购买电影院的门票。他们提供信用卡付款和许多其他服务，甚至不提供 IAP。

他们以某种方式到达了商店，所以我建议你提前和苹果谈谈，看看他们是否会批准你的商业模式。

如果购买的内容包含 100% 真实世界的对象或服务并且不会改变应用程序本身的行为或内容，他们可能会批准其他付款方式。

Answer 4

不，你不能。每个 iOS 应用都必须符合的商店审核指南为了获得苹果公司的通过，明确指出：
- 您不得使用“应用内购买 API (IAP) 以外的系统来购买内容、功能或服务”进行付款 (11.2)
- 不允许“使用[e] IAP 购买实体商品或在应用程序之外使用的商品和服务”

事实上，有一个 Paypal 的 API 用于此目的，但是，如上所述，使用它的应用程序将不会通过审核。

Answer 5

有可能，但据我所知，Appstore 不允许使用 PayPal API。执行此操作的方法是将用户发送到将处理付款的网站。这里您可以使用 PHP API 为例。
