Good afternoon, I have a question about InAppPurchases Auto-Renewable Subscription. Paid subscriptions can be cancelled at any time. Where and when to check the expiration date (and possible cancellation date) inside the application ? Do I need to call restoreCompletedTransactions every time in didFinishLauchingWithOptions to get the current date ?

Good afternoon. I have such a question. When I download the app in the app store, I will be asked: "Is your app designed to use cryptography or does it contain or incorporate cryptography?". I have a private library that I license for each individual project. I am provided with project parameters (Application name, BundleID, etc.). And I generate (independently, manually) several keys, I use for base64 and AES256. Then I insert these constants into the library. The library has a security mechanism. Every time an application that uses my library is launched, it extracts some project parameters, converts them to AES256/base64, and compares them with its constants. If they differ, it means that the framework was inserted into a project for which I did not license the use of the framework. What should I choose in iTunes connect ? Does my application (which uses a library that has a pirate protection mechanism) use encryption ? P.S. I also have a class in the library that contains different methods for converting NSString to NSData and vice versa. Below it will be .h file. I only use a part of them, just to check the license. THE LICENSE is checked locally on the device ! I don't send the data anywhere. objective-c /* CommonHMAC-------------------------------------------------*/ @interface NSData (CommonHMAC) (NSData*) HMACWithAlgorithm:(CCHmacAlgorithm) algorithm; (NSData*) HMACWithAlgorithm:(CCHmacAlgorithm) algorithm key:(id)key; @end /* CommonCryptor--------------------------------------------------------*/ @interface NSData (CommonCryptor) (NSData*) AES256EncryptedDataUsingKey:(id)key error:(NSError **) error; (NSData*) decryptedAES256DataUsingKey:(id)key error:(NSError **) error; (NSData*) DESEncryptedDataUsingKey:(id)key error:(NSError **) error; (NSData*) decryptedDESDataUsingKey:(id)key error:(NSError **) error; (NSData*) CASTEncryptedDataUsingKey:(id)key error:(NSError **) error; (NSData*) decryptedCASTDataUsingKey:(id)key error:(NSError **) error; @end /* CommonDigest--------------------------------------------------------*/ @interface NSData (CommonDigest) (NSData*) MD2Sum; (NSData*) MD4Sum; (NSData*) MD5Sum; (NSData*) SHA1Hash; (NSData*) SHA224Hash; (NSData*) SHA256Hash; (NSData*) SHA384Hash; (NSData*) SHA512Hash; @end

Greetings to all apple developers! I have the problem with NETunnelProviderManager and PacketTunnelProvider. When I try to make a connection (by OpenVPN), there is an instant disconnect. I am using OpenVPNAdapter.framework - https://github.com/ss-abramchuk/OpenVPNAdapter for this. I put nslog in all methods in PacketTunnelProvider and none were printed.... I have the following logs in the console: objective-c NEVPNStatusInvalid Save successfully Connection established! NEVPNStatusConnecting NEVPNStatusDisconnected I checked all the .entitlements and other parameters. As I think they are okay. However, if you could check them again, I would be grateful. Below I am pasting links to images.

Maybe in PacketTunnelProvider ? The code for PacketTunnelProvider was taken from here. - https://github.com/yaooort/OpenVPN-IOS/blob/master/PacketTunnel/PacketTunnelProvider.m All tests I run on a real device (iPhone iOS 12.4.4) Xcode Version 12.4 (12D4e) My .ovpn file is correct because it good works on android version of application. Please help me, I don't know where to look for the answer. There are similar questions on stackoverflow, but no one answered them.
