Would it be possible to add inapp purchase inside extensions in iOS 8? For example, a custom keyboard may have free and pro versions based on inapp purchase.
Thanks a lot in advance.

You should probably handle in-app purchases in the app itself, as the name suggests. – Andrew Jul 09 '14 at 03:16

The custom keyboard requires a container app anyhow, it would probably be a good idea to do it there. You could likely have UI on your keyboard interface to link to the app via openURL: directing users on how to purchase the "Pro" version. With that said, you can tell which APIs are not accessible if they are annotated with the NS_EXTENSION_UNAVAILABLE_IOS macro. You can see this on [UIApplication sharedApplication] as an example. If none of the StoreKit APIs you need to perform the purchase are marked as unavailable, it's likely that you'll be able to get it done within the extension.
