UItableviewController doesn't load data

Hi guys i have a UITableviewcontroller class, i am calling it from otherview and pushing it on the navigationcontroller.

Streets_view_Controller_iPhone * street_controller = [[Streets_view_Controller_iPhone alloc]initWithStyle:UITableViewStylePlain];
        street_controller.riding_number =  [assignment objectForKey:@"Riding_Number"];
        street_controller.polling_number = [assignment objectForKey:@"Poll"];




        [self.navigationController pushView开发者_开发技巧Controller:street_controller
                                             animated:YES];

and here is my tableview controller class "Streets_view_Controller_iPhone.m"

#import "Streets_view_Controller_iPhone.h"


@implementation Streets_view_Controller_iPhone

@synthesize polling_number;
@synthesize data;

But for some reason i amnot getting anything in the cell, just the title of the view i.e Streets . and empty table

Nothing will show up in your table because of the following:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 0;
}

You must have at least one section in your table for it to show any data. Try return 1; and see if it works.
