iOS Back from tableview

[iphonejudy]

I used MainWindow.xib as my home page.

From that i add navigationcontroller.I want to go back to the mainwindow from the navigation controller.

I used the below code in the rootviewcontroller.m.But it did not work.

- (IBAction)back:(id)sender {
JsonappAppDelegate *Delegate1 = [[UIApplication sharedApplication] delegate];

	[Delegate1.navigationController popViewControllerAnimated:YES];
}

[self.view removeFromSuperview];
[window makeKeyAndVisible];

I used the above code for navigating the mainwindow.xib from the navigationcontroller.But the controls in the view are not working.
