Divide NSDate by day and time

Question

I am trying to split the NSDate I receive from a web service into two different dates in order to populate the View table for sectioned events for each day. I decided that the least difficult way to do this is to create a fetch request that searches for unique days.

So, I'm trying to create an "day" NSDate, but the time component is set to 00:00. I wonder if there is a more efficient way to achieve this:

if (eventoItemList.count > 0) { NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; NSDateFormatter *dayFormatter = [[NSDateFormatter alloc] init]; [dayFormatter setDateFormat:@"yyyy-MM-dd"]; for (GDataXMLElement *eventoItem in eventoItemList) { BOEvent *event = [[BOEvent alloc] init]; NSString *idEventStr = [[[eventoItem elementsForName:@"id"] objectAtIndex:0] stringValue]; NSString *name = [[[eventoItem elementsForName:@"titulo"] objectAtIndex:0] stringValue]; NSString *type = [[[eventoItem elementsForName:@"tipo"] objectAtIndex:0] stringValue]; NSString *descr = [[[eventoItem elementsForName:@"descripcion"] objectAtIndex:0] stringValue]; NSString *address = [[[eventoItem elementsForName:@"direccion"] objectAtIndex:0] stringValue]; NSDate *date = [dateFormatter dateFromString:[[[eventoItem elementsForName:@"fecha"] objectAtIndex:0] stringValue]]; NSString *action = [[[eventoItem elementsForName:@"accion"] objectAtIndex:0] stringValue]; [event setIdEvent:[idEventStr integerValue]]; [event setName:name]; [event setType:type]; [event setDesc:descr]; [event setAddress:address]; [event setAction:action]; [event setDate:date]; [event setDayDate:[dayFormatter dateFromString:[dayFormatter stringFromDate:date]]]; [events addObject:event]; } } 

Thank you for your help.

sample code to split NSDate into two NSDates (date only, time only)

  NSDate *date = [NSDate date]; NSCalendar *gregorian = [NSCalendar currentCalendar]; unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit; NSDateComponents *comps = [gregorian components:unitFlags fromDate:date]; NSDate *dateOnly = [gregorian dateFromComponents:comps]; unitFlags = NSHourCalendarUnit | NSMinuteCalendarUnit | NSDayCalendarUnit; comps = [gregorian components:unitFlags fromDate:date]; NSDate *timeOnly = [gregorian dateFromComponents:comps]; NSLog(@"%@ = \n\tDate: %@ \n\tTime: %@", date, dateOnly, timeOnly);

sample code to output NSDate in two NSStrings

  NSDate *date = [NSDate date]; NSDateFormatter *f = [[NSDateFormatter alloc] init]; [f setDateStyle:NSDateFormatterFullStyle]; [f setTimeStyle:NSDateFormatterNoStyle]; NSString *dateOnly = [f stringFromDate:date]; [f setTimeStyle:NSDateFormatterFullStyle]; [f setDateStyle:NSDateFormatterNoStyle]; NSString *timeOnly = [f stringFromDate:date]; NSLog(@"%@ = \n\tDate: %@ \n\tTime: %@", date, dateOnly, timeOnly);
