3.1 Payments
3.1.1 In-App Purchase:
· If you want to unlock features or functionality within your app, (by way of example: subscriptions, in-game currencies, game levels, access to premium content, or unlocking a full version), you must use in-app purchase. Apps may not use their own mechanisms to unlock content or functionality, such as license keys, augmented reality markers, QR codes, etc. Apps and their metadata may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase.
如果你想在你的应用程序中解锁功能或功能，(例如:订阅、游戏内货币、游戏级别、访问高级内容或解锁完整版本)，你必须使用应用内购买。应用程序可能不会使用它们自己的机制来解锁内容或功能，例如许可密钥、增强现实标记、二维码等。应用程序及其元数据可能不包括按钮、外部链接或其他行动呼叫，这些呼叫会引导客户到应用程序内购买以外的购买机制。
· Apps may use in-app purchase currencies to enable customers to “tip” digital content providers in the app.
应用程序可以使用应用程序内购买货币，使客户能够在应用程序中“提示”数字内容提供商。
· Any credits or in-game currencies purchased via in-app purchase may not expire, and you should make sure you have a restore mechanism for any restorable in-app purchases.
通过应用程序内购买的任何积分或游戏内货币可能不会过期，您应该确保对任何可恢复的应用程序内购买有一个恢复机制。
· Remember to assign the correct purchasability type or your app will be rejected.
记住要指定正确的可购买类型，否则你的应用程序将被拒绝。
· Apps should not directly or indirectly enable gifting of in-app purchase content, features, or consumable items to others.
应用程序不应直接或间接允许向他人赠送应用程序内购买的内容、功能或消耗品。
· Apps distributed via the Mac App Store may host plug-ins or extensions that are enabled with mechanisms other than the App Store.
通过Mac应用程序商店分发的应用程序可能会托管由应用程序商店以外的机制启用的插件或扩展。
· Apps offering “loot boxes” or other mechanisms that provide randomized virtual items for purchase must disclose the odds of receiving each type of item to customers prior to purchase.
提供“战利品箱”或提供随机虚拟物品购买的其他机制的应用程序必须在购买前向客户披露收到每种物品的几率。
· Non-subscription apps may offer a free time-based trial period before presenting a full unlock option by setting up a Non-Consumable IAP item at Price Tier 0 that follows the naming convention: “XX-day Trial.” Prior to the start of the trial, your app must clearly identify its duration, the content or services that will no longer be accessible when the trial ends, and any downstream charges the user would need to pay for full functionality. Learn more about managing content access and the duration of the trial period using Receipts and Device Check.
非订阅应用程序可以提供一个免费的基于时间的试用期，然后提供一个完整的解锁选项，方法是按照命名约定，以0级价格设置一个不可消费的IAP项目:“XX-day试用。”“在试用开始之前，你的应用程序必须清楚地识别它的持续时间、试用结束后无法访问的内容或服务，以及用户需要支付的所有下游费用。”了解更多关于使用Receipts和Device Check管理内容访问和试用期持续时间的信息。
