i using xcode 5 , want search tableview data. used "search bar & search display controller" "searching", "customcell" "tablecell" , data parsing remote server nsxmlparsing. data showing corresponding image without problem how search option doesn't work properly. same code single array searsing , working. here isn't. @ time of searching crashed. here code:

-(void)loaddata {     countryparser = [[countryparser alloc] loadxmlbyurl:@"http://www.avowstudio.com/ios/partproject/ios7/xmlparsingwithcustomecell/xmlfiles/xmlparsingwithcustomcell.xml"];      countryarray = [countryparser countryarray];      displayitems = [[nsmutablearray alloc] initwitharray:countryarray];      [self.countrytableview reloaddata];     [activityindicator stopanimating];     [self loadarray]; }    -(void) loadarray {     countryinfo *currentcountryone = [[countryinfo alloc] init];     totalarray = [[nsmutablearray alloc] init];      (int i=0; < [countryarray count]; i++)     {         currentcountryone = [countryarray objectatindex:i];         [totalarray addobject:currentcountryone.countryname];     } }   -(void) searchbar:(uisearchbar *)searchbar textdidchange:(nsstring *)searchtext {     if ([searchtext length] == 0)     {         [displayitems removeallobjects];         [displayitems addobjectsfromarray:countryarray];     }     else     {         [displayitems removeallobjects];         displayitems = [[nsmutablearray alloc] init];          (nsstring *string in totalarray)         {             nsrange stringrang = [string rangeofstring:searchtext options:nscaseinsensitivesearch];             if (stringrang.location != nsnotfound)             {                 [displayitems addobject:string];             }         }     }     [self.countrytableview reloaddata]; }    - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {     return [displayitems count]; }  // method kept "tablerow height" after "done searching" - (void)searchdisplaycontroller:(uisearchdisplaycontroller *)controller didloadsearchresultstableview:(uitableview *)tableview {     tableview.rowheight = 100; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifier = @"cell";      countrycustomcell *cell = [self.countrytableview dequeuereusablecellwithidentifier:cellidentifier];      if (!cell)     {         cell = [[countrycustomcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:cellidentifier];     }      currentcountry = [displayitems objectatindex:indexpath.row];      cell.continentlabel.text = currentcountry.continent;     cell.countrynamelabel.text = currentcountry.countryname;     cell.capitallabel.text = currentcountry.capital;      imagequeuecountryflag = dispatch_get_global_queue(dispatch_queue_priority_high, 0ul); dispatch_async(imagequeuecountryflag, ^     {         uiimage *imagecountryflag = [uiimage imagewithdata:[nsdata datawithcontentsofurl: [nsurl urlwithstring:[currentcountry countryflag]]]];     dispatch_async(dispatch_get_main_queue(), ^         {             cell.countryflagimageview.image = imagecountryflag;             [cell setneedslayout];         });     });  return cell; 

}

i don't want use 2 array in "numberofrowsinsection" & "cellforrowatindexpath" flag or thing that, avoid more coding. if 1 familiar please share here. lot of in advanced.

i think added objects of countryinfo in [countryparser countryarray]. in loadarray method, initializing blank object currentcountryone , each time loop executes, trying add blank object's property totalarray. please make changes below:

-(void) loadarray {     totalarray = countryarray; }   -(void) searchbar:(uisearchbar *)searchbar textdidchange:(nsstring *)searchtext {     if ([searchtext length] == 0)     {         [displayitems removeallobjects];         [displayitems addobjectsfromarray:countryarray];     }     else     {         [displayitems removeallobjects];         displayitems = [[nsmutablearray alloc] init];          (countryinfo *country in totalarray)         {             nsrange stringrang = [country.countryname rangeofstring:searchtext options:nscaseinsensitivesearch];             if (stringrang.location != nsnotfound)             {                 [displayitems addobject:country];             }         }     }     [self.countrytableview reloaddata]; }
