objective c - (MagicalRecord) NSDate in relatedByAttribute -


I have an object that I import with the following JSON structure using magical record I am: 

  {"Receipts": [{"Date": "2014/03/05", "Zodiac": "199.00"}, {"Date": "2014/03 / 04 "," zodiac "" 9.00 "}, {" date ":" 2014/03/01 "," zodiac ":" 9.00 "}}}   
  receipt  object with two values, date and amount. According to the business requirements, this date will always be unique, in this way, I want to use it for 'related bay attribute' for that NSManid object. However, when I do this with the Magic Records error:  
  *** Canceling 'FIS' without exception 'NSInvalidArgumentException', Reason: '- [__ NSCF stringing time Interlacedins Refreshdate]: In the codeet on the 0x178034500 '/ code>  
  Receif  object sent to an unknown selector, I have the date attribute set "Related Behavior" on the date itself As a specialty of "I Format: I also set the yyyy / MM / dd "in the user information. Regarding the relationship of  receipt , I have a  commission  object in relation to "related beet attribute: date".  
 In Yoga: What?  
 For all those people, more details about this issue are being discussed through magazines tracker.   
 
 
 To solve this issue I  receif  objects on  Identifier  has added property. I made it a string and set  the map name  to  date . After this I have kept my current  date  property (i.e.  dateFormat  to  yyyy / MM / dd ). I again changed my related section to  identifier . It works like a charm!  
 Big "ah!" For me, when I realized that magical amount gives you the ability to map many properties into a single JSON feature. Now my  date  property is a NSDT that I want and I have a unique string  identifier .
