thanks

when app in foreground state call

application:didreceiveremotenotification:

but if it's not , app launched, example, swiping alert in notification center

application:didfinishlaunchingwithoptions:

is called key. way call

application:didreceiveremotenotification:

from

application:didfinishlaunchingwithoptions:

i believe should help

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     if (launchoptions[uiapplicationlaunchoptionsremotenotificationkey]) {         [self application:application didreceiveremotenotification:launchoptions[uiapplicationlaunchoptionsremotenotificationkey]];     }     // code...     return yes; } 

// extended

try storyboard that:

// make sure name match uistoryboard *mainstoryboard = [uistoryboard storyboardwithname:@"mainstoryboard" bundle:nil];  

create object mainstoryboard:

updatepoliticalviewcontroller *ringingvc = [mainstoryboard instantiateviewcontrollerwithidentifier:@"updatepoliticalviewcontroller"]; 

and try set new root view controller

[self.window setrootviewcontroller: ringingvc];
