Hi. So we are trying to add push notifications to an existing Qt Desktop application. Mac OS is first priority.
However, I can't figure out how to get to NSApplication to register to APN. I looked here, although it's for iOS and Android: https://github.com/gympulsr/qt-pushnotifications Simple code so converted to MacOS, mostly changed the mm file: #include <AppKit/NSApplication.h> #include "pushnotification.h" @interface QMacOSApplicationDeligate @end //add a category to AppDelegate @interface QMacOSApplicationDeligate (QPushNotificationDelegate) @end @implementation QMacOSApplicationDeligate (QPushNotificationDelegate) - (BOOL)application:(NSApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //-- Set Notification [application registerForRemoteNotifications]; return YES; } - (void)application:(NSApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSLog(@"Did Register for Remote Notifications with Device Token (%@)", deviceToken); // const unsigned *tokenBytes = (const unsigned*)[deviceToken bytes]; // NSString *tokenStr = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x", // ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]), // ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]), // ntohl(tokenBytes[6]), ntohl(tokenBytes[7])]; // PushNotificationRegistrationTokenHandler::instance()->setAPNSRegistrationToken(QString::fromNSString(tokenStr)); } - (void)application:(NSApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { NSLog(@"Did Fail to Register for Remote Notifications"); NSLog(@"%@, %@", error, error.localizedDescription); } @end But, I'm getting exactly this issue, looks like they were trying to do almost the same thing. I can't figure out how I can do this, any suggestions? https://interest.qt-project.narkive.com/6v9o61We/objective-c-category-for-qcocoaapplicationdelegate-undefined-symbols -- Wes Krasko www.worldwidewes.com www.kraskofamily.com "Stay away from negative people.
