Answer 1

Try to check inside didReceiveRemoteNotification

 - (void)application:(UIApplication *)application 
    didReceiveRemoteNotification:(NSDictionary *)userInfo 
    fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

delegate method to receive remote notification in all state.

If you want to show the notification alert in active state. use HDNotificationView to show notification alert.

like this:

if(application.applicationState == UIApplicationStateActive) {

[HDNotificationView showNotificationViewWithImage:[UIImage imageNamed:@"Icon-40.png"]
                                                            title:title
                                                          message:message
                                                       isAutoHide:YES
                                                          onTouch:^{
                                                              /// On touch handle. You can hide notification view or do something
                                                              [HDNotificationView hideNotificationViewOnComplete:nil];
                                                          }];
}

Add an UIAlertView inside didReceiveRemoteNotification and check if you are receiving notification in active state. Check below code

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo  {

        if (application.applicationState == UIApplicationStateActive) {                              
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Received a Notification" message:[NSString stringWithFormat:@"My App received  notification while it is running:\n%@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]]delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [alertView show];          
        }    
    }

When Push Notification received to your app Application can be one the below 5 states Reference:: https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/TheAppLifeCycle/TheAppLifeCycle.html

1)Not running

2)Inactive

3)Background

4)Suspended

5)Active

If application state is 1,2,3,4 then iOS will handle and will display banner In case of 5(Active state) our app needs to handle this case In this case below method will be called

Reference:: https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623013-application?language=objc

- (void)application:(UIApplication *)application 
didReceiveRemoteNotification:(NSDictionary *)userInfo 
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler;

here you need to check state of app using application.state == Active then you can do what ever you want ideal case here we need to display alert .
