Choosing Calendar to add an iOS event

问题:

I'm trying to add events to the calendar in iOS devices, for now I've got to add an event to the defaultCalendarForNewEvents calendar, but what I want is to be able to choose a calendar that has already been created in which I want to add the event.

For example in the following capture it is seen that there is an iphone calendar and then there may be 1 or several gmail created

What I want to do is that you can choose the calendar in which you want to add the event, this calendar must be created earlier, not that the system chooses the calendar.

Any recommendations? Any examples?

P.D: I'm starting to code with objective-c and ios

Code to add events I'm testing and it works:

- (void) addEventCalendar: (Evento_DTO *) evento {
    EKEventStore *eventStore = [[EKEventStore alloc] init];
    EKEvent *event = [EKEvent eventWithEventStore:eventStore];
    EKReminder *reminder = [EKReminder reminderWithEventStore:eventStore];


    event.title = @"Test Event";
    reminder.title = @"Test reminder";

    NSDate *cDate = [NSDate date];
    NSLog(@"current date  %@", cDate);


    /*NSDateComponents *startDateComponents = [[[NSDateComponents alloc] init] autorelease];
     [startDateComponents setDay:12];
     [startDateComponents setMonth:12];
     [startDateComponents setYear:2012];
     [startDateComponents setHour:12];
     [startDateComponents setMinute:18];


     NSDateComponents *endDateComponents = [[[NSDateComponents alloc] init] autorelease];
     [endDateComponents setDay:12];
     [endDateComponents setMonth:12];
     [endDateComponents setYear:2012];
     [endDateComponents setHour:12];
     [endDateComponents setMinute:18];
     [endDateComponents setSecond:20];*/


    //event.startDate = cDate;
    //event.endDate = [cDate dateByAddingTimeInterval:15.0];

    event.startDate = [cDate dateByAddingTimeInterval:((5*60*60) + (30 * 60) + 15)];
    event.endDate = [cDate dateByAddingTimeInterval:((5*60*60) + (30 * 60) + 30)];


    //event.startDate = [[NSCalendar currentCalendar] dateFromComponents:startDateComponents];
    //event.endDate = [[NSCalendar currentCalendar] dateFromComponents:endDateComponents];

    reminder.completionDate = [cDate dateByAddingTimeInterval:((5*60*60) + (30 * 60) + 10)];

    NSLog(@"startdate  %@", event.startDate);
    NSLog(@"enddate  %@", event.endDate);


    [event setCalendar:[eventStore defaultCalendarForNewEvents]];

    //[reminder setCalendar:[eventStore defaultCalendarForNewReminders]];

    NSError *error = nil;

    [eventStore saveEvent:event span:EKSpanThisEvent commit:YES error:&error];
    //[eventStore saveReminder:reminder commit:YES error:&error];
}

Try this by creating new calendar.

 -(EKEvent*)createEvent:(EKEventStore*)eventStore{
        EKEvent *event = [EKEvent eventWithEventStore:eventStore];
        event.title = @"New Event";

        event.startDate = [NSDate date];
        event.endDate =[NSDate date];

        event.location=@"Location";
        event.allDay = YES;
        event.notes =@"Event description";

        NSString* calendarName = @"Calendar";
        EKCalendar* calendar;
        EKSource* localSource;
        for (EKSource *source in eventStore.sources){
            if (source.sourceType == EKSourceTypeCalDAV &&
                [source.title isEqualToString:@"iCloud"]){
                localSource = source;
                break;
            }
        }
        if (localSource == nil){
            for (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;
}

Hope it will work. Let me know if you have any query.

-(void)addEventOnCalendar{
    EKEventStore *store = [EKEventStore new];
    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (!granted) {
            return;
        }
        EKEvent *event = [EKEvent eventWithEventStore:store];
        event.title = @"What ever You want to save as your event";
        event.startDate = selectedDate;

        event.endDate = selectedDate1;

        event.calendar = [store defaultCalendarForNewEvents];
        NSError *err = nil;
        [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];

    }];
    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Message" message:@"Event Successfully added in Calender" delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
    [alert show];
}

First of all, thank @NarendraPandey and @nehamishra for the help provided

I have given the solution to my problem, which will then put the solution in case someone can serve you.

I have created a method to obtain the available calendars that are local and those of gmail, the code is the following one:

- (NSMutableArray*) getCalendars {

    NSMutableArray *res =[[NSMutableArray alloc] init];

    EKEventStore *eventStore = [[EKEventStore alloc] init];
    EKEntityType type = EKEntityTypeEvent;
    NSArray *calendars = [eventStore calendarsForEntityType: type];

    for ( EKCalendar *cal in calendars )
    {
        if (cal.type == EKCalendarTypeCalDAV || cal.type == EKCalendarTypeLocal  ){
            NSLog(@"cal nombre:- %@ ", cal.title);
            [res addObject: cal];

        }
    }

    return res;
}

Then to show the list of calendars so that the user can select one and enter the events there, I found that Ihave to use an Action Sheet, although I have seen that it was deprecated according to some forum comments Of StackOverflow, so I used UIAlertController, being as follows:

NSMutableArray* cals =  [self getCalendars];

if([cals count] > 0){//Comprobamos que existan calendarios

   UIAlertController *alert = [UIAlertController   alertControllerWithTitle:AMLocalizedString(@"calendar_dialog_info", @"")
          message:nil
          preferredStyle:UIAlertControllerStyleActionSheet];

   for ( EKCalendar *cal in cals )
   {
         UIAlertAction *calAction = [UIAlertAction actionWithTitle: cal.title
         style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {

         NSLog(@"You pressed button %@ ", cal.title);

         [self descargarCalendario:  cal];
          }];

          [alert addAction:calAction];
   }

   UIAlertAction* cancel = [UIAlertAction
                                         actionWithTitle:AMLocalizedString(@"cancelar", @"")
               style:UIAlertActionStyleCancel
               handler:^(UIAlertAction * action)
               {
                    [alert dismissViewControllerAnimated:YES completion:nil];

               }];

         [alert addAction:cancel];

         [self presentViewController:alert animated:YES completion:nil];
}else{
    NSLog(@"No hay calendarios");
}

Where the [self downloadCalendario: cal]; function is responsible for downloading some events from a web service and adding them to the chosen calendar.

Resulting in the following view to choose the calendar:

And the code to add the event to the selected calendar is:

-(void)addEventOnCalendar: (EKCalendar *) cal{

    EKEventStore *store = [EKEventStore new];
    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (!granted) {
            return;
        }
        EKEvent *event = [EKEvent eventWithEventStore:store];
        event.title = @"Test";

        NSDate *cDate = [NSDate date];
        event.startDate = [cDate dateByAddingTimeInterval:((5*60*60) + (30 * 60) + 15)];
        event.endDate = [cDate dateByAddingTimeInterval:((5*60*60) + (30 * 60) + 15)];

        //event.calendar = [store defaultCalendarForNewEvents];
        event.calendar = [store calendarWithIdentifier: cal.calendarIdentifier];

        NSError *err = nil;
        [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];

    }];
    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Message" message:@"Event Successfully added " delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
    [alert show];

}

I hope it helps somebody.
