How to Maintain Presenting View Controller's Orientation When Dismissing Modal View Controller

How to maintain presenting view controller's orientation when dismissing modal view controller?

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if ([self.window.rootViewController.presentedViewController isKindOfClass: [SecondViewController class]])
{
    SecondViewController *secondController = (SecondViewController *) self.window.rootViewController.presentedViewController;

    if (secondController.isPresented)
        return UIInterfaceOrientationMaskAll;
    else return UIInterfaceOrientationMaskPortrait;
}
else return UIInterfaceOrientationMaskPortrait;
}

And for Swift

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow) -> Int {

    if self.window?.rootViewController?.presentedViewController? is SecondViewController {

        let secondController = self.window!.rootViewController.presentedViewController as SecondViewController

        if secondController.isPresented {
            return Int(UIInterfaceOrientationMask.All.toRaw());
        } else {
            return Int(UIInterfaceOrientationMask.Portrait.toRaw());
        }
    } else {
        return Int(UIInterfaceOrientationMask.Portrait.toRaw());
    }

}

Maintaining orientation of parent view after modal view has been presented with different orientation

I think the problem is your use of application:supportedInterfaceOrientationsForWindow:. Instead, get rid of that, and start with a UINavigationController subclass and make that the class of the root view controller that is your navigation interface. Then:

• In the UINavigationController subclass, return UIInterfaceOrientationMaskLandscape from supportedInterfaceOrientations.

• In the presented (modal) view controller, return UIInterfaceOrientationMaskAll from supportedInterfaceOrientations.

Portrait orientation in all view controllers except in modal view controller

In appDelegate:

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }

special UINavigationController subclass (if you using navigation controller) with methods:

- (NSUInteger)supportedInterfaceOrientations {
    if (self.topViewController.presentedViewController) {
        return self.topViewController.presentedViewController.supportedInterfaceOrientations;
    }
    return self.topViewController.supportedInterfaceOrientations;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return self.topViewController.preferredInterfaceOrientationForPresentation;
}

each view controller should return it's own supported orientations and preferred presentation orientation:

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationPortrait;
}

my app works in portrait, but video player opens as modal vc with:

 - (NSUInteger)supportedInterfaceOrientations {
     return UIInterfaceOrientationMaskAllButUpsideDown;
 }

 - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
     return UIInterfaceOrientationLandscapeLeft;
 }

It works perfect for me, hope it helps!

iOS8 - prevent rotation on presenting viewController

So after long days of searching and investigating, I finally came up with a possible solution.

First of all, I can use navigation controller and push the viewController instead of presenting it, but it breaks my code and just isn't so true.

The second thing I can do is not setting constraints. I still can use autolayout, but if I don't set constraints, and let the default constraints to be set, the tableView doesn't get reloaded. of course this is also isn't very smart thing to do, as I have many elements in my viewController.

Finally, I figured out that I can show this "modal" viewController in another UIWindow. I create UIWindow and set the modalViewController as its rootViewController.

I put some example project in git:
https://github.com/OrenRosen/ModalInWindow

Hope it will be helpful.
