core data - iOS UICollectionView and CoreData -


i'm new ios , still trying wrap head around basics (my newbie disclaimer). i'm starting play persistent data , presenting data uicollectionview.

i can create cells , right number arrays, i'm having issues right number of cells interacting core data. i'll try example clarify: have entity person attributes first name , last name. have 1 person saved. when number of objects in section, 1 object 1 person. number used create # of cells 1 1 person. i'd create 2 cells (one first name , 1 last name) each person, can't figure out. tried putting each entity own section , using arithmetic return 2 * #of entities in section, hat crashes.

this seems rather simple can't figure out?

in numberofsectionsincollectionview:: 

return 1;

in collectionview:numberofitemsinsection::

return fetcheddata.count*2;

in collectionview:cellforitematindexpath:: 

person *p = fetcheddata[indexpath.row/2]; // integer division ... cell.textlabel = indexpath.row % 2 ?          p.firstname     // odd row number        :p.lastname;     // row number
