Some time ago I studied the in-APP purchase technology and used the scam e-book to submit it to Apple for approval. You can read a certain number of chapters for free. If you want to read them completely, you must purchase them in the app.
Once purchased, you can always read it. If it is deleted, you can use the "resume purchase" button in the application to restore the existing purchase. Although there are a lot of downloads, there are not many "purchase" reading.
At least it indicates that the in-APP purchase technology is already available on the iphone.
Then we will study the advertising technology. That is, embedding an advertisement in an application. Select several, and finally select the MobWIN advertising platform. Considering that the iPhone app may be difficult to review after being added to the advertisement, I wrote the "fraud story" ebook on the android mobile phone. The first version was soon written and submitted to the MobWIN platform for review and online promotion. However, e-books on android are not able to flip pages on the iphone, so they are not satisfied. After a few days, the android mobile phone has also achieved the page flip effect, almost the same as the page flip effect on the iphone.
