ios - Reminder App using Core Data and TableView -

how can create table each section there titles such dates , dates duplicate different times included in section same date? ios calendar.

i not use eventstore , calendar, , reason work using core data , have created data model inside created date attribute.

let me give example, sample output:

reminder 04/23/2014 17:33:32.502 [2654:60 b] (      "4/22/2014 16:45:42 +0000",       "4/22/2014 16:50:25 +0000",       "4/23/2014 17:50:03 +0000",       "24/4/2014 15:45:43 +0000"  ) 

my thought is:

the sections of tableview should 3, takes dates of 22, 23 , 24 , in section 22, there must 2 dates of 22 different times.

any advice on how move?
