ios - cellForItemAtIndexPath is Changing Multiple Cells When Should Change One -

-

i may not understanding reusing of cells behaviour uicollectionview can tell me why 2 cells having properties changed in cellforitematindexpath when should 1 cell.

here's code.

-(uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath {    photocollectionviewcell *cell = (photocollectionviewcell *) [collectionview dequeuereusablecellwithreuseidentifier:@"photocollectionviewcell" forindexpath:indexpath];    if (![[self.userphotos objectatindex:indexpath.row] isequaltostring:@""]){     nsstring *photourl = [self.userphotos objectatindex:indexpath.row];      nsurl *imageurl = [nsurl urlwithstring: photourl];     nsurlrequest *imagerequest = [nsurlrequest requestwithurl:imageurl];    [cell.photoimageview setimagewithurlrequest:imagerequest placeholderimage:[uiimage imagenamed:@"animage"] success:^(nsurlrequest *request, nshttpurlresponse *response, uiimage *image) {        cell.photoimageview.image = image;       cell.photoimageview.frame = cgrectmake(0, 0, 100.0f,100.0f);       cell.photoimageview.contentmode = uiviewcontentmodescaleaspectfit;        [cell.deleteimageview setframe:cgrectmake(-4.0f,-4.0f,28.0f,28.0f)];       cell.deleteimageview.layer.cornerradius = cell.deleteimageview.frame.size.width / 2;       [cell.deleteimageview setalpha:0.8f];       cell.deleteimageview.layer.borderwidth = 1.0f;       cell.deleteimageview.layer.bordercolor = [uicolor redcolor].cgcolor;      } failure:^(nsurlrequest *request, nshttpurlresponse *response, nserror *error) {       nslog(@"%@",[error localizeddescription]);     }];   }else{     cell.photoimageview.image = [uiimage imagenamed:@"camera"];     cell.photoimageview.layer.borderwidth = 1.0f;     cell.photoimageview.layer.bordercolor = [uicolor lightgraycolor].cgcolor;     nslog(@"setting alpha & hiding delete");     cell.photoimageview.alpha = 0.4f;     [cell.deleteimageview sethidden:yes];   }

the code in else part being executed on cells 2 , 6 example when should 6. although logging says it's executed on 6

any idea i'm going wrong?

thanks.
