ios - cell properties returned nil -

i created custom uitableviewcell named gatecell, inside placed 1 label , 1 text field.
in gatecell.h

@property (weak, nonatomic) iboutlet uilabel *gatelabel; @property (weak, nonatomic) iboutlet uitextfield *gatetextfield; 

in gatetableviewcontroller

- (void)viewdidload {     [self.tableview registerclass:[gatecell class] forcellreuseidentifier:@"cellidentifier"]; } 

finally @ cellforrowatindexpath method, used this

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     gatecell *cell = (gatecell *)[tableview dequeuereusablecellwithidentifier:@"cellidentifier"];     cell.gatelabel.text = @"gate";     cell.gatetextfield.text = @"open gate"     return cell; } 

when print description of cell, getting following..

<`gatecell`: 0x7b6bd790; baseclass = `uitableviewcell`; frame = (0 0; 320 44); layer = <calayer: 0x7b6c2e60>> <br> 

printing description of cell->_gatelabel:

nil

printing description of cell->_gatetextfield:

nil

why label , textfield returns nil when cell created ???

first thing ensure connected iboutlet interface builder. if not connect iboutlet. getting cell use following

uitableviewcell *cell = [tableview      dequeuereusablecellwithidentifier:@"cellreuseidentifier"];
