如何在Apple的SampleDetailViews样本的详细视图中推送视图控制器？

Question

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 = [[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 ?

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 Its simple and works much better then some of the complex and outdated options i found so far.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 .

Answer 3

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];
