用于免费试用的 iPhone 应用内购买 [英] iPhone In-App Purchases for Free-Trials

问题描述

我正在向应用商店发布应用程序.我最近看到您可以免费提供应用程序，但可以进行应用程序内购买.当我看到这个时，我认为这可以用来创建一个免费试用版.但是，在 Apple 的 有关在免费应用程序中使用应用内购买的有用提示 中，它说><块引用>

不要设置任何时间限制您的应用程序的功能，无论是为了运行时间或生命时间.应用只运行一定数量的每个会话的分钟数，或到期一段时间后，不要招募客户那么多在他们的嘴里留下不好的味道.

我知道有时很难知道 Apple 的想法，但这是否意味着他们将不允许应用内免费试用，或者他们对此不屑一顾.有人知道有人试过这样做吗?

解决方案

如您引用的文字所示，他们将拒绝任何试用"的应用程序，因为它只能在有限的时间或使用次数.

如果您想删除高级功能并允许用户付费，那完全可以接受.事实上，这是他们谈论的主要用例之一.请记住，该应用的免费版本(在人们为高级功能付费之前)应该做一些有用的事情，并且不应该过期.

此外，需要注意的是占位符"功能，这会让您被拒绝.例如，如果你制作了一款游戏并且有必须购买的难度级别，你不能让它看起来像是可以选择这些难度级别，然后在用户尝试选择它们时提示用户付费.您可以告诉用户缺少难度级别并鼓励他们升级，但是，这是一个微妙但重要的区别.

I am in the process of releasing an application to the app-store. I recently saw that you can make your application free but have in-app purchases. When I saw this I thought that this could be used to create a free trial. However in Apple's Helpful Tips for Using In App Purchase In Free Apps it says

Don’t set time limits on any of the functionality of your app, either for run times or life times. Applications that only run for a set number of minutes per session, or that expire altogether after some period of time, don’t recruit customers so much as leave a bad taste in their mouths.

I know that sometimes it's tough to know what Apple is thinking but does this mean they will not allow In-App Free Trials or that they frown upon it. Does anybody know if people have tried doing this?

解决方案

As indicated in your quoted text, they will reject any app that is a "trial" in that it only works for a limited amount of time or number of uses.

If you want to remove advanced functionality and allow users to pay for them, that's perfectly acceptable. In fact, it's one of the main use cases they talk about. Just keep in mind that the free version of the app (before people pay for the advanced features) should do something useful, and it should not expire.

Also, something to watch out for is "placeholder" functionality, which will get you rejected. For example, if you make a game and have difficulty levels that must be purchased, you can't make it look like those difficulty levels can be selected and then prompt the user to pay for them once they try to select them. You can tell the user that there are missing difficulty levels and encourage them to upgrade, however, which is a subtle but important distinction.
