XCode Tutorial: In-App Purchase

In-App Purchase is something highly requested and something to get developers a little extra money from their apps. Whether it's buying a song, a game level, or a book, it comes in handy. No need to create separate apps for the things you were making for the app.

@iwin28647 For content, such as new game levels, I include them in my app, and instead of downloading a file when the payment request gos through it sets a Boolean value to yes, when the Boolean is set to yes the levels become playable by the user. Hope that helps :)

@Pumpy032 Yes, but where is the boolean stored? In a plist file?

[MacOSeX10]

@Pumpy032 Bad idea users with jailbroken devices can get in the files and change the boolean to yes and that way you lose money and thats bad!

[SimpleSDK]

@MacOSeX10 Exactly, but it depends where the value is stored.

paymentWithProductIdentifiers is deprecated, what should I do ?

Just FYI with iOS 5 being out, instead of saving files to the Documents folder, they need to be saved to the Caches folder or the app will get rejected.

@MacOSeX10 or you can add "security keys" as I call them which have a specific huge value set when the boolean is true or false. If they change the boolean, but the security codes don't match the value, you could make the app crash. For example, if they had purchased the content, there could be a security key set to 102948, and if it's not purchased, the key would be set to 938473. If the key either doesn't match the boolean or is another number, they're a hacker and you would crash the app.
