Trying To Use Without Storyboard

[ozanonurtek]

Hello,
I really like your project and I run your demo project in emulator and it works fine
My question is;
Since I m not using storyboard I try push my viewcontroller when cell is tapped, like bellow
DetailViewController *d = [DetailViewController new];
d.detailView.headerImageView = cell.cellImageView;
[self.navigationController pushViewController:d animated:NO];
But it doesnt work
Any idea how to achieve this one?
Thanks :)
