#import <uikit/uikit.h>  @interface historicocell : uitableviewcell  @property (weak, nonatomic) iboutlet uilabel *lblcodigo; @property (weak, nonatomic) iboutlet uibutton *btnfavoritar;  @end 

secondviewcontroller.h

    #import <uikit/uikit.h>  @interface secondviewcontroller : uiviewcontroller <uitableviewdatasource, uitableviewdelegate>  @property (weak, nonatomic) iboutlet uitableview *tblhistorico; 

secondviewcontroller.m

you should set cell indentifier "cellidentifier" cell in file inspector

or register nib file if add cell nib:

uinib *itemnib = [uinib nibwithnibname:@"yourcell" bundle:nil]; [self.tableview registernib:itemnib forcellreuseidentifier:@"yourcellreuseindentifier"];
