objective c - iOS Notifications: callbacks not called -

i'm implenting reminder feature app through local notifications. user setup times , repetition intervals , app schedule respective notifications this:

uilocalnotification *notification = ...; [[uiapplication sharedapplication] schedulelocalnotification:notification]; 

for work need register notification types this:

uiusernotificationsettings *notificationsettings;  notificationsettings = [uiusernotificationsettings                          settingsfortypes:uiusernotificationtypealert                                categories:nil];  [[uiapplication sharedapplication]   registerusernotificationsettings:notificationsettings]; 

although notifications scheduled correctly none of appdelegate callbacks (didregisterusernotificationsettings, didreceivelocalnotification) called. need react notifications when app in foreground.

registering notification settings should trigger callback message in appdelegate:

- (void)application:(uiapplication *)application         didregisterusernotificationsettings:(uiusernotificationsettings *)notificationsettings {    nslog(@"callback called."); } 

it works fine quick test project (new project -> single view app -> add register code , callback -> launch). callback gets called.

however, in real app not work.

i completly stripped apps appdelegate (removed custom init code, no ui loading) registers notification settings. fresh app install triggers user confirmation dialog correctly. callbacks won't called.

am missing build setting/compiler flag? i'm not aware of special settings app pointing in direction. can't spot difference example project.

xcode 7.2 , ipod5 ios9.2.1

ouch. makes perfect reason facepalm...

in order detect ui events within whole app, appdelegate changed exdend uiapplication use - (void)sendevent:(uievent *)event callback. appdelegate should extend uiresponder.

you can setup different classes both uses in main.m:

int main(int argc, char *argv[]) {   @autoreleasepool {     @try {       // original appdelegate extending uiresponder       nsstring *maindelegate = nsstringfromclass([appdelegate class]);       // new class extending uiapplication       nsstring *mainclass    = nsstringfromclass([appmain class]);        return uiapplicationmain(argc, argv, mainclass, maindelegate);     }     @catch (nsexception *exception) {       nslog(@"%@", [exception reason]);     }   } } 

i thank suggestions. have take step back.
