I want to build an app which selling teaching course through in-app purchase.
The teaching course content contains text, images and video.
But, how to define a digital book?
First of all, youtube search in app purchase. I belive SimpleSDK has a tutorial on it. From there you can unlock anything you want. If you want to start making a digital book. Just start googling about it, its not that hard.
Do you know where do the digital book files (in-app purchase items) store?
keep in App Store server or our own server?
You can keep the files in your app. Whenever they purchase it though it is unlocked from the app. It is already there but it is just locked. Check the youtube tutorial.
Dont even think about keeping the files in your app. If you have jailbroken your iPhone/iPad you can have easy access to those files any time you want. Its best to keep them on the app store.

Obviously you did not understand what he wants to do. He wants to be able to get digital books through in app purchase. If he submits it to the App Store it will be rejected for keeping it in a cydia utility. Learn to read.
iSDK is right, however Chessin you are wrong. The app would not be rejected from the app store as it is NOT keeping a cydia utility. You should not comment on threads if you do not know what you are talking about. Where is he keeping a cydia utility in that app?

Are you serious. In-App Purchase CAN unlock something already in the app or it CAN download something from a server. What I am not sure of is what does Cydia have anything to do with this. He wants the users to be able to purchase a book through the app and get it in the app. What is so hard to understand?
Cydia has nothing to do with this, no one has mentioned cydia apart from you. There is no utility being kept in the app which would get it rejected. iSDK is just trying to prove a point that the app can be hacked by a jailbroken device owner and therefore the owner can then use the paid material without having to buy the in-app purchase.

Alright fine, but this is a non-jailbreak forum if you haven't noticed. No one should ever bring up jb anything. And if you want to prevent jb hackers from getting your in app content for free, you just implement some anti-piracy code like I did in my app.

Also I forgot to bring up something. No matter where the paying user gets it from ex: App Store, server, in app unlock ... the cracked app can still have access to that content for free because the person who cracks the app has it downloaded into their app and will be distributed with it. But I suppose one way around this would to delete those files when the app closes and then re download it next time it is open but it could take a while for it to download depending on how big the IAP files are.
In-App Purchase for text, image, video
Linear Mode
