ios - Is there a way to determine the order of the self.collectionview.visiblecells? -

on collection view, know first item that's being displayed on collection view. figured @ visiblecells , first item on list, it's not case.

returning first item visible on collectionview:

uicollectionviewcell *cell = [self.collectionview.visiblecells firstobject]; 

returning first item from items in collectionview

uicollectionviewcell *cell = [self.collectionview cellforitematindexpath:[nsindexpath indexpathforitem:0 insection:0]]; 

you don't want cell, data:

nsindexpath *indexpath = [[self.collectionview indexpathsforvisibleitems] firstobject]; id yourdata = self.datasource[indexpath.row]; 

but visivlecells array not ordered!!

well, need order it:

nsarray *indexpaths = [self.collectionview indexpathsforvisibleitems]; nssortdescriptor *sort = [nssortdescriptor sortdescriptorwithkey:@"row" ascending:yes];  nsarray *orderedindexpaths = [indexpaths sortedarrayusingdescriptors:@[sort]]; // orderedindexpaths[0] return position of first cell. // can cell or data datasource accessing .row 

edit: believe visiblecells (and like) return ordered already, didn't find regarding on docs. added ordering part make sure.
