ios - Segue not passing data between ViewControllers -

i making ios app uses payment methods.

at moment trying work on checkout flow, contains oderformviewcontroller , checkouttableviewcontroller can see below:

i connected both dragging segue, highlighted in blue. added segue identifier segue.

i called first view controller e_orderformviewcontroller(its title shipping address), , in created ibactionfor continue button , used -(void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender pass in information.

i have order model, properties in it. on checkouttableviewcontroller, have got labels , orderinfo public properties, first view controller 1 can access it.

#import <foundation/foundation.h>  @interface order : nsobject  @property(strong, nonatomic) nsstring *shippingname; @property (strong, nonatomic) nsstring *shippingaddress; @property (strong, nonatomic) nsstring *shippingcity; @property(strong, nonatomic) nsstring *shippingstate; @property(strong, nonatomic) nsstring *shippingzip;   @end   //e_orderformviewcontroller.m  #import "e_orderformviewcontroller.h" #import "f_checkouttableviewcontroller.h"  ...  #pragma mark - actions - (ibaction)storepaymentinfoproceedtoconfirmation:(id)sender {   [self performseguewithidentifier:@"tocheckout" sender:self]; }  #pragma mark - navigation -(void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender{    if ([[segue identifier] isequaltostring:@"tocheckout"]) {     f_checkouttableviewcontroller *checkoutview = segue.destinationviewcontroller;      //store information , pass next view     checkoutview.orderinfo.shippingname = self.txtfieldnameoncard.text;      nslog(@"shipping name stored: %@",checkoutview.orderinfo.shippingname);   }  } 

my nslog returns (null) whatever text type inside first textfield, 1 testing first.

here checkouttableviewcontroller, public property. orderinfois listed here. using pass in information, mentioned above:

//f_checkouttableviewcontroller.h  #import <uikit/uikit.h>  @interface f_checkouttableviewcontroller : uitableviewcontroller  @property (strong, nonatomic)order *orderinfo;  @end 

on viewdidload, on destination view controller, did:

//f_checkouttableviewcontroller.m  @implementation f_checkouttableviewcontroller  - (void)viewdidload {     [super viewdidload];    //load information    self.labelshippingname.text = self.orderinfo.shippingname;    nslog(@"typed name: %@",self.orderinfo.shippingname);  } 

i pasted viewdidload reference, aware if nslog in prepareforsegue not returning anything, information not being passed.

i don't know error is. searched in couple of threads here on stackoverflow, , none of them helped me, 1 seems similar, one, didn't issue:

multiple segues not passing object data between themselves

this seems pretty simple, making mistake can not find.

i appreciate help.

orderinfo must null, because didn't initialize it, therfore cannot set properties... got 2 options:

checkoutview.orderinfo = [[orderinfo alloc]init]; checkoutview.orderinfo.shippingname = self.txtfieldnameoncard.text; 

or change property from:

@property (strong, nonatomic)order *orderinfo; 

to:

@property (strong, nonatomic)nsstring *shippingname ;
