iOS / objective-c / xcode：在代码中实例化DetailView控制器

Question

I had some code for launching a modal view controller created in storyboard with a storyboard ID. For a new situation, I am trying to adapt it to present a ViewController that is actually the detail view of a table in the main navigational system. I'm trying to jump around in the app if that is possible.

In this case, the VC should not be modal. Instead, I want to take the user to the normal detail view of a table.

To make it more challenging, I need the detail view to have the object data. Fortunately, this should be present in the starting VC.

Here is my code for launching a modal VC.

 UIStoryboard *storyBoard = self.storyboard;
         detailVC *newVC =
         [storyBoard instantiateViewControllerWithIdentifier:@"detailView"];
         //pass object to new VC
         detailVC.object = _object;//pass data object
         UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController: dareVC];
         [self presentModalViewController:nav animated:YES];

Edit: Following code does launch non-modal VC. However, initial detail view is devoid of data. The data is saved so if I come back to it, the data is there but initially, I get generic screen with no data.

  detailVC *secondViewController =
         [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];
         [self.navigationController pushViewController:secondViewController animated:YES];
         secondViewController.object=_object;

Answer 1

  detailVC *secondViewController =
         [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];
         secondViewController.object=_object;
         [self.navigationController pushViewController:secondViewController animated:YES];

First instantiate it. Then set the data. Then push it.
