iphone - Change UICollectionViewCell content and nib layout based on data -

i have uicollectionview displaying many uicollectionviewcells have subclassed cardcell. pass variable "type" cardcell in - (uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath want cardcell class able load different nib file depending on type passed in. different types need have different layouts.

the problem cannot figure out change in cardcell.m. tried using - (void)prepareforreuse not call unless user scrolling.

you should register each nib file need in viewdidload, (substituting correct names nib file , identifier):

[self.collectionview registernib:[uinib nibwithnibname:@"rdcell" bundle:nil] forcellwithreuseidentifier:@"firsttype"]; 

then, in itemforrowatindexpath, test type , return correct type of cell:

 - (uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath {         if (type = @"firsttype") {             firstcell *cell = (firstcell *) [collectionview dequeuereusablecellwithreuseidentifier:@"firsttype" forindexpath:indexpath];             return cell;         }else{             secondcell *cell = (secondcell *) [collectionview dequeuereusablecellwithreuseidentifier:@"secondtype" forindexpath:indexpath];             cell.whatever .....             return cell;         } }
