在Xcode8中不调用

Question

我使用iOS 10SDK在Xcode 8上构建我的应用程序。iOS 9.3设备未调用didRegisterForRemoteNotificationsWithDeviceToken，因此iOS 9.3及以下设备无法接收推送通知。但iOS 10设备可以接收推送。如果我使用iOS 9.3SDK在Xcode7.3上构建相同的应用程序，那么iOS 9设备就可以接收推送。所以，我确信我的所有设置都应该是正确的。

这是我的实现：

// Push notification
if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) )
{
    if([application respondsToSelector:@selector(registerUserNotificationSettings:)])
    {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];

    }
    else
    {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
    }


}
else
{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
     {
         if( !error )
         {
             [[UIApplication sharedApplication] registerForRemoteNotifications];
         }

     }];
}


- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

NSString * tokenAsString = [[[deviceToken description]
                             stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]]
                            stringByReplacingOccurrencesOfString:@" " withString:@""];

}



- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {

DLog(@"app didFailToRegisterForRemoteNotificationsWithError: %@", error.description);
}

Answer 1

为什么要使用过时的方法?？[[UIApplication sharedApplication] registerForRemoteNotificationTypes:

当我移除它的时候

[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)categories:nil]];

并使用

[[UIApplication sharedApplication] registerForRemoteNotifications];

我从APN拿到了令牌。

您需要从didFinishLaunchingWithOptions调用registerForNotifications方法。

 func registerForNotifications(){
        if #available(iOS 10.0, *) {
            let center = UNUserNotificationCenter.current()
            center.delegate = self
            center.requestAuthorization(options:[.alert,.sound,.badge]) { (granted, error) in
                if granted{
                    UIApplication.shared.registerForRemoteNotifications()
                }else{
                    print("Notification permission denied.")

                }
            }

        } else {
            // For iOS 9 and Below
            let type: UIUserNotificationType = [.alert,.sound,.badge];
            let setting = UIUserNotificationSettings(types: type, categories: nil);
            UIApplication.shared.registerUserNotificationSettings(setting);
            UIApplication.shared.registerForRemoteNotifications()
        }
    }

 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let token = String(format: "%@", deviceToken as CVarArg).trimmingCharacters(in: CharacterSet(charactersIn: "<>")).replacingOccurrences(of: " ", with: "")
        print(token)
    }


extension AppDelegate : UNUserNotificationCenterDelegate{
    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {
        print("Handle push from foreground”)

        let info = ((notification.request.content.userInfo as NSDictionary).value(forKey: "aps") as! NSDictionary)
        if let type = info.value(forKey: "type") as? Int{
            if type == 0 {   // notification arrive
                handlePush(apsDict: (notification.request.content.userInfo as NSDictionary))
            }
        }
    }
    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print("Handle push from background or closed")

        let info = ((response.notification.request.content.userInfo as NSDictionary).value(forKey: "aps") as! NSDictionary)
        if let type = info.value(forKey: "type") as? Int{
            if type == 0 {   // notification arrive
                handlePush(apsDict: (response.notification.request.content.userInfo as NSDictionary))
            }
        }
    }
}
