Question

here is my productscontroller.h

ProductListViewController *productListViewController;
ProductGridViewController *productGridViewController;
UIButton *flipIndicatorButton;  

and i am adding list and gridview as a subview like this in my implementation

ProductListViewController *listController = [[ProductListViewController alloc] initWithNibName:@"ProductListView" bundle:nil];
self.productListViewController = listController;
self.productListViewController.CurrentSale = CurrentSale;
[self.view insertSubview:listController.view atIndex:0];

but in when i tried to push detailview controller from ProductListViewController.m like this

ProductDetailViewController *productDetailViewController = [[ProductDetailViewController alloc] init];

productDetailViewController.productIndexPath = indexPath;

[self.navigationController pushViewController:productDetailViewController animated:YES];

it just does not work, then i check [self.navigationController] , it was nil,
now how to deal with this problem. i am ready to give some more code and detail to make more clear. thanks

Answer 1

i found workaround for this problem.
now what i am doing is i am passing ref of parent controller in this case ProductsController and written method to push next view. following this now i am calling parent method to push next view like this
[parent pushNextview];
so far it works fine, hope this is good way of doing what i wanted to.
