Background

A product similar to QQ, with QQ coins. We had to integrate In-App Purchase — no amount of explaining would do.

When a created product is rejected, the SKProduct’s localizeTitle is nil. In most cases this is enough to crash the program.

For the product’s language description, don’t mention the price (the price should be obtained from price). Write the detailed description in more detail: after entering the app, where to tap to get to the purchase page, which button to tap to buy the current product, and what the effect is after purchasing.
Apple’s product review and app review are done by different people.
Apple’s phone notification is a different person from the product or app reviewer.
Apple’s phone notification is in Chinese.
Apple will use an iPad to test an iPhone app.
Because the program crashes when localizeTitle is nil after a product is rejected, the Apple reviewer doesn’t know this is the reason; they’ll only say they tested many devices and it always crashes, and a program that crashes can’t pass review.
The phone number you submit for review must be correct — Apple does make phone calls.

Handling one case of IAP payment failure in a multi-account app. See these two questions:

When I have time and find a solution, I’ll add it here

The information returned by Apple’s server when validating receipts is reliable; you can get the purchased product ID, quantity, price, etc. from here.
For more safety, you can compare it once more against what the client uploaded.
A receipt may contain multiple products. (Perhaps a network anomaly last time caused the receipt to contain multiple products.)
On the server side, read the docs carefully: some fields in the json returned by receipt validation are arrays.

文章目录

产品类似QQ，有QQ币。必须集成In-App Purchase, 怎么解释都不行。

产品的语言描述，不要出现价格（价格要从price中获取）。详细描述要写的详细一些，进入App后，从哪里点击能进入到购买页面，点击哪个按钮可以购买当前产品，购买后效果如何。
苹果的产品审核与App审核是不同的人。
苹果的电话通知与产品或App审核是不同的人。
苹果的电话通知是用中文。
苹果会拿iPad测试iPhone的App。
由于产品被拒绝后，localizeTitle为nil导致程序崩溃，苹果审核人员是不知道这个原因的，他们只会说测试过很多设备，总是崩溃，崩溃的程序是不能通过审核的。
提交审核的电话一定要正确，苹果是会打电话的。

有时间找到解决办法后，再补充到这里
