how to handle Notification when app State is UIApplicationStateInactive - ios

Question

I am using following code to handle push notification.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
if(application.applicationState == UIApplicationStateInactive)
{
//************************************************************
// I only want this called when user click on notification.
//************************************************************
NSLog(#"Inactive");
if ([[userInfo valueForKey:#"noty_type"] isEqualToString:#"web"])
{
if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:[userInfo valueForKey:#"url"]]])
{
dispatch_async(dispatch_get_global_queue (DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[userInfo valueForKey:#"url"]]];
});
}
}
}
if((application.applicationState == UIApplicationStateActive)
{
// I am useing local notification when app in Forground
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.soundName = #"Default";
localNotification.alertBody = [userInfo valueForKey:#"msg"];
localNotification.userInfo = userInfo;
[[UIApplication sharedApplication] scheduleLocalNotification: localNotification];
}
}
This code open the url in safari browser. this code work fine When my app in background and notification come and I click on notification check the applicationState and open the url with [[UIApplication sharedApplication] openURL.
now the scenario that generate the problem.
I open my app .
and Down the notification UI
now Send the notification from server
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler method get called.
Now I get the ApplicationState == UIApplicationStateInactive .
"It open into the safari browser without any user interaction".
I only want this called when user click on notification.
So, How can I handle this condition ?

Answer 1

Try this.
if (application.applicationState == UIApplicationStateInactive || application.applicationState == UIApplicationStateBackground)
{
// do something when app open with notification
}

You have to know why the app is inactive. The two possibilities are that the app was in the background and the user is bringing it to the foreground (by tapping on the notification banner), or something like the notification center was pulled down or the user got a system alert.
To tell the difference, keep track of when the user enters the background. Just set a boolean in the applicationDidEnterBackground: delegate method, and clear it when the app is resigning active.
static BOOL didEnterBackground;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Launching the app is kind of like coming from background.
didEnterEnterBackground = YES;
return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application {
didEnterBackground = NO;
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
didEnterBackground = YES;
}
Now you can check the variable didEnterBackground to determine how the app got to the inactive state when you're handling a notification.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
if (application.applicationState == UIApplicationStateInactive) {
if (didEnterBackground) {
// The user tapped the notification
}
else {
// The app was inactive, but not in the background.
// Ignore notification, or do whatever the app does
// when receiving a notification while active.
}
}
}

Hope this help you
-(void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
}//iOS below 9
- (void)application:(UIApplication *)application
handleActionWithIdentifier:(nullable NSString *)identifier
forLocalNotification:(nonnull UILocalNotification *)notification
completionHandler:(nonnull void (^)())completionHandler {
// handling local and interactive notifcation
} // iOS 9 and above
Which is used to trigger the notification in background state.
