Question

UPDATE

I ended up fixing the issues with MGSplitViewController, so I am now using this fork of the project: http://github.com/ArtSabintsev/MGSplitViewController At the time of writing this edit, the fork hasn’t been pulled into Matt Gemmell’s master branch.

Please Note

1. My iPad app is Landscape only, and is iOS5 and iOS6 compatible
2. I have a partially working solution, but I need to take it one step further.
3. For the majority of the screens in my app, I need to present both the master and detail views (normal behavior).
4. At one point, I need to only the detailVC to be present.

How am I doing it now?

I am using the following UISpliterViewControllerDelegate Method

- (BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation
{
    return self.hideRootViewController;
}

where hideRootViewController is a boolean that is set to NO initially.

The Partial Solution

If I change the boolean to YES (in any screen/VC in my app) and rotate the screen, the masterVC disappears, and the detailVC occupies the entire screen.

The Remaining Problem

How do I force this change without physically having to rotate the device, or how do I force a device orientation notification change to redraw UISplitViewController?

The following attempts have failed:

1. CGAffineTansformation (Identity and small angle transformations)
2. Posting a UIDeviceOrientationDidChangeNotification
3. Calling setNeedsLayout on splitVC.view
4. Presenting and immediately dismissing modalVC’s on splitVC

Note: I am not using MGSplitViewController, nor do I want to use that class in this project.

Answer 1

Why dont you use mgsplitviewcontroller. I used it in my project, it works wonderful and very easy implement. You can able hide/switch master view easily.
