How to get Application states in iOS 10 notification? - ios

Question

I am using
userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler
for getting the notification response in iOS 10, can anyone tell me how to get the Application states in it ?
Because in iOS 9 or before I used
application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
In this method, we can get the application state by
application.applicationState
thanks for the help.

Answer 1

You can get application's state from anywhere in your project something like,
UIApplication *applicaiton = [UIApplication sharedApplication];
if (applicaiton.applicationState == UIApplicationStateBackground) {
NSLog(#"background state");
}
same like you can use UIApplicationStateActive,UIApplicationStateInactive etc to get respective state

I did some search and I got these methods
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog( #"for handling push in foreground" );
// Your code
NSLog(#"%#", notification.request.content.userInfo); //for getting response payload data
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
NSLog( #"for handling push in background" );
// Your code
NSLog(#"%#", notification.request.content.userInfo); //for getting response payload data
}

Something like this:
NSString * state = #"Unknown";
UIApplication *application = [UIApplication sharedApplication];
if ( application.applicationState == UIApplicationStateInactive ) {
//The application received the notification from an inactive state, i.e. the user tapped the "View" button for the alert.
//If the visible view controller in your view controller stack isn't the one you need then show the right one.
state = #"UIApplicationStateInactive";
}
if(application.applicationState == UIApplicationStateActive ) {
//The application received a notification in the active state, so you can display an alert view or do something appropriate.
state = #"UIApplicationStateActive";
}
if(application.applicationState == UIApplicationStateBackground ) {
state = #"UIApplicationStateBackground";
}
