How can I push view controllers in detail view of Apple's sample MultipleDetailViews?

my intent is to implement something similar to native iPad Settings app. Settings use UITableViewController and, as such, in detail view can drill down to subviews, however I want to be able to push a view controller via button tap in my detail view.

So I've tried to extend MultipleDetailViews sample application:

1) SecondDetailViewController has property navigationController (which is read-only) set to nil...

2) So I created a new UINavigationController and used it to push my controllers, but that didn't work.

My code:

if (!self.myNavigationController) {
    self.myNavigationController = [开发者_如何学编程[UINavigationController alloc] initWithRootViewController:self];
}

FirstDetailViewController *controller = [[FirstDetailViewController alloc] initWithNibName:@"FirstDetailView" bundle:nil];

[[self myNavigationController] pushViewController:controller animated:YES];

[controller release], controller = nil;

Also tried just init method on UINavigationController, but didn't work as well.

Am I trying something that is not possible without implementing custom UISplitViewController? Was I misled by the sample code that for SecondDetailViewController has UINavigationBar?

To be able to do this you have to push the viewController on to each viewController in the array. Like so:

[[self.appDelegate.splitViewController.viewControllers objectAtIndex:0] pushViewController:rootLevel1 animated:YES];
[[self.appDelegate.splitViewController.viewControllers objectAtIndex:1] pushViewController:detailLevel1 animated:YES];

I was searching for the solution to a similar problem. In my case i wanted tableview to link to multiple detailviews depending on the selection. I could overlay the data on one viewcontroller but was seeking a better solution. Here is what i did. Its simple and works much better then some of the complex and outdated options i found so far.

I simply gave a storyboard ID in the identity inspector to the viewcontroller that i wanted showing up in the detailview ("second") and upon didSelectRowAtIndexPath i simply added:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
 TimeDetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"second"];

[[self.splitViewController.viewControllers objectAtIndex:1] pushViewController:detail animated:YES];

  }

So when someone presses a cell in the master view, the detail view is pushed.

A simple if statement can switch which view is shown:

   if ([[self.selfRootMenuArray objectAtIndex:indexPath.row] isEqual: @"Second Choice"]) {
        TimeDetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"second"];

[[self.splitViewController.viewControllers objectAtIndex:1] pushViewController:detail animated:YES];

  else if ([[self.selfRootMenuArray objectAtIndex:indexPath.row] isEqual: @"First Choice"]) {
        TimeDetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"first"];

[[self.splitViewController.viewControllers objectAtIndex:1] pushViewController:detail animated:YES];

    };

You could simply use buttons, switches or anything else instead of a table view but the point is that by adding a "Storyboard ID" in the "Identity Inspector"

and simply instantiating the view controller by referencing the "Storyboard ID" and then pushing it to the split view controller at index 1 (detail side) its simple and quick

 TimeDetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"second"];

[[self.splitViewController.viewControllers objectAtIndex:1] pushViewController:detail animated:YES];

You can do it using:

showDetailViewController(viewController, sender: nil)

Documentation from Apple about it is here.
