GetNeedItemsViewController *getNeedItemsViewController = [[GetNeedItemsViewController alloc] initWithNibName:@"GetNeedItemsViewController" bundle:nil];
[self.navigationController pushViewController:getNeedItemsViewController animated:YES];

I dont know why the getNeedItemsViewController doesn’t displayed.
Help me with this, thank you in advance!
Have you added content on the
GetNeedItemsViewController? From the image it looks like it is added but that it is empty. And at the moment you have a memory leak. One option is toauto-releaseit the controller.
