objective c - iOS: Open a Calendar app New Event screen with populated date -

is possible redirect user calendar app new event screen programmatically populated start , end dates? aware of introduction calendars , reminders, seems overkill. have tried calshow://, didn't seem work either or couldn't find correct scheme.

@import eventkit; @import eventkitui; 

then present eventkit using this:

- (ibaction)scheduleclicked:(id)sender {  ekeventstore *eventstore = [[ekeventstore alloc]init]; if([eventstore respondstoselector:@selector(requestaccesstoentitytype:completion:)]) {     [eventstore requestaccesstoentitytype:ekentitytypeevent completion:^(bool granted,nserror* error){         if(!granted){         nsstring *message = @"hey! project can't access calendar... check privacy settings let in!";         dispatch_async(dispatch_get_main_queue(), ^{    // present alert warning.             });         }else{              ekeventeditviewcontroller *addcontroller = [[ekeventeditviewcontroller alloc] initwithnibname:nil bundle:nil];             addcontroller.event = [self createevent:eventstore];             addcontroller.eventstore = eventstore;              [self presentviewcontroller:addcontroller animated:yes completion:nil];             addcontroller.editviewdelegate = self;             }     }];   } } 

meanwhile there delegates giving detail of end dates start date of calendar.

#pragma mark - eventeditdelegates - - (void)eventeditviewcontroller:(ekeventeditviewcontroller *)controller didcompletewithaction:(ekeventeditviewaction)action{     if (action ==ekeventeditviewactioncanceled) {         [self dismissviewcontrolleranimated:yes completion:nil];     }     if (action==ekeventeditviewactionsaved) {         [self dismissviewcontrolleranimated:yes completion:nil];     } }   #pragma mark - createevent - -(ekevent*)createevent:(ekeventstore*)eventstore{     ekevent *event = [ekevent eventwitheventstore:eventstore];     event.title = @"new event";      event.startdate = @"your start date";     event.enddate = @"your end date";      event.location=@"location";     event.allday = yes;     event.notes =@"event description";      nsstring* calendarname = @"calendar";     ekcalendar* calendar;     eksource* localsource;     (eksource *source in eventstore.sources){         if (source.sourcetype == eksourcetypecaldav &&             [source.title isequaltostring:@"icloud"]){             localsource = source;             break;         }     }     if (localsource == nil){         (eksource *source in eventstore.sources){             if (source.sourcetype == eksourcetypelocal){                 localsource = source;                 break;             }         }     }     calendar = [ekcalendar calendarforentitytype:ekentitytypeevent eventstore:eventstore];     calendar.source = localsource;     calendar.title = calendarname;     nserror* error;    [eventstore savecalendar:calendar commit:yes error:&error];     return event; } 

this createevent create new calendar
