How to show a light reasonable cell selected image / color ?


i'm using table 1 row , uitableviewcellaccessorydisclosureindicator allow selection of value. i'm using disabled button show stretched image in cell.

however, selectedbackgroundview can't seem show other dark blue color or image, uitableviewcellselectionstylegray.

can't understand why seems complicated.

can offer me advice ?

if want customise selected background colour possible, rather more involved might (see seloc tech wiki app in signature example: uses uitableviews lot customised colours: selected highlights green).

first of setup cell correctly:

code:
  // called cell table view.  if required create cell , setup required customisation  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath  {	  	static nsstring *myidentifier = @"myidentifier";  	  	// try retrieve table view now-unused cell given identifier  	uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:myidentifier];  	  	// if no cell available, create new 1 using given identifier  	if (cell == nil)  	{  		// 3.0 changed: initwithframe:reuseidentifier: depricated replace suggested new method  		cell = [[[uitableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:myidentifier] autorelease];  		// want have green text green highlights match our overall branding/theme  		cell.textlabel.textcolor = seloc_green;  		cell.selectedbackgroundview = [[[colourabletablecellbackgroundview alloc] init] autorelease];  		cell.selectedbackgroundview.clearscontextbeforedrawing = no;  		cell.selectedbackgroundview.backgroundcolor = [uicolor clearcolor];  		((colourabletablecellbackgroundview *) cell.selectedbackgroundview).cellbackgroundcolor = seloc_green;  	}  	[cell.backgroundview setneedsdisplay];  	  	return cell;  }
note seloc_green #define uicolor.

need custom view:

.h
