See below Inbox APIs to get & delete inbox messages, we also provide an open source example of Inbox implementation (provided on the demo application on Github).
// Getting inbox messages [[Appoxee shared] refreshInboxWithCompletionHandler:^(NSError *appoxeeError, id data) { if (!appoxeeError) { NSArray *messages = (NSArray *)data; // all objects in array are of type APXRichMessage } }]; // Deleting inbox messages [[Appoxee shared] deleteRichMessage:richMessage withHandler:^(NSError *appoxeeError, id data) { if (!appoxeeError) { // refresh UI } }];
