I had the same problem as you do. It's actually quite tricky because you can have done "perform segue in collectionHeaderView" perfectly in an empty project(I tried). I found the key to this problem is your RootVC of navigation controller isn't the initial VC of the app.
You can get around this by adding the lines below in your .m file that presents the rootVC of navigation controller.

- (IBAction)next:(id)sender {
[theRootVCinNavigationController] *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"[your identifier]"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:[theRootVCinNavigationController]];
[self presentViewController:navigationController animated:YES completion:nil];
}
