Apple draws 15% to 30% commission on the sales of virtual goods in the developer's App, which is called "Apple tax" in the industry and cannot be returned.

On 20 17, wechat turned off the reward function because apple failed to discuss the issue of extracting 30% of users' rewards. At that time, there were today's headlines, such as Zhihu, Yingke Platform and so on. In its official website Apple developer agreement, Apple clearly stipulated that "Apple is responsible for the global payment processing" and "the developer keeps 70% of the sales revenue".
