ios - Cell.selectedBackgroundview not showing -

-

cell.selectedbackgroundview isn't working. have figured out selectedview placed behind image in cell resulting in no visible image (i worked out making image small saw tick behind image). there way fix this? code seems fine must have layers

static nsstring *identifier = @"cell";  uicollectionviewcell *cell = [collectionview dequeuereusablecellwithreuseidentifier:identifier forindexpath:indexpath]; uiimageview *productimages = (uiimageview *)[cell viewwithtag:100]; productimages.image = [uiimage imagenamed:[allproducts_sections[indexpath.section]objectatindex:indexpath.row]];   collectionview.backgroundcolor = [uicolor greencolor];   cell.selectedbackgroundview = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"tick 1.png"]]; collectionview.allowsmultipleselection = yes; return cell

as can see blue selected backgroundview , blackbox image why doesnt selectedbackgorundview go on black box

-(uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {   static nsstring * cellidentifier = @"cell";   uitableviewcell * cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];   if (cell==nil)    {     cell = [[uitableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:cellidentifier];   //some code   }   uiview *selectedbackview=[[uiview alloc]initwithframe:cell.bounds];   uiimageview *selectionimg = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"tick 1.png"]];   [selectedbackview addsubview:selectionimg];   cell.selectedbackgroundview=selectedbackview;   return cell; }

also make sure tick 1.png in project's bundle.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
