uitableview - Search bar in core data project -

i use core data magical record , i'm try filter data search bar in table view.

i write 2 methods number of rows , name of cells:

    -(int) damminumerocercati:(nsstring *)searchbar {     nspredicate *predicate = [nspredicate predicatewithformat:@"nome contains [cd] %@", searchbar];      nsarray*arra = [ricetta mr_findallsortedby:@"nome" ascending:yes withpredicate:predicate];       return arra.count; } -(nsstring*) damminomericettacercata:(nsstring *)searchbar mostratanellacella: (int) cella {     nspredicate *predicate = [nspredicate predicatewithformat:@"nome contains [cd] %@", searchbar];      nsarray *arra = [ricetta mr_findallsortedby:@"nome" ascending:yes withpredicate:predicate];     ricetta*ctn = arra[cella];      return [nsstring stringwithformat:@"%@", ctn.nome]; } 

then call method inside numberofrowsinsection: , cellforrowatindexpath: inside if cycle:

if (self.mysearchbar.isfirstresponder){  // above methods  } else {  // normals methods have data } 

somebody know i'm wrong or if miss somethings?

searchbar uisearchbar, not string.

you should use searchbar.text , process in methods.

also, in table view's datasource methods have make sure table view causing callback, , return correct count/string. checked comparing pointers 2 tables (original table view , search results table view).

-(nsuinteger)tableview:(uitableview*)tableview         numberofrowsinsection:(nsuinteger)section {     if (tableview == _tableview) {       // return usual row count    }    return [self damminumerocercati:_searchbar.text]; }
