hi new objective c. trying create login system app.

here how story board looks like:

enter image description here

i using afnetworking classes , rest php library talk data.

now can see created navigations first app using push, modal , navigation.

where stucked

when user click on sign in button in app app first authorise user , take user find places view.

what need when click on sign in button, first place finder view open , call function display data of places using rest api eith json format. 

 - (ibaction)signin:(id)sender {   [self performseguewithidentifier:@"landingview" sender:sender];   }   - (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     if ([[segue identifier] isequaltostring:@"landingview"]) {    // here call function -"display_place" of class -"showplaces"????     }  }

i hope can idea if going right or should next?

thanks

you can use destinationviewcontroller property segue:

 - (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     if ([[segue identifier] isequaltostring:@"landingview"]) {       [((showplaces *)segue.destinationviewcontroller) display_places];    }  }

by way, not using proper naming of classes , functions... should take @ other examples , tutorials see how code style objective c.
