In Following code i added two UIBarButton with flexSpace..
you can add UIBarButton as you want

UIToolbar *Toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    Toolbar.barStyle = UIBarStyleBlackTranslucent;
    [Toolbar sizeToFit];

     NSMutableArray *barItems = [[NSMutableArray alloc] init];
    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
    [barItems addObject:flexSpace];
    [flexSpace release];

    UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(Cancel)];
    [barItems addObject:btnCancel];

    UIBarButtonItem *btnDone = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(done)];
    [barItems addObject:btnDone];

    [Toolbar setItems:barItems animated:YES];

Following Method is call when tapped on bar Button

-(void)Cancel
{
  // Write Code for Cancel Method
}

-(void)done
{
  // Write Code for Done Method
}
