My Info.plist contains:
Supported interface orientations =
<array>
<string>UIInterfaceOrientationPortrait</string>
<string>UIInterfaceOrientationLandscapeLeft</string>
<string>UIInterfaceOrientationLandscapeRight</string>
<string>UIInterfaceOrientationPortraitUpsideDown</string>
</array>
as it should, because on iPad all orientations are allowed.

Yes. But this thing I have not created (nor subclassed). Probably created by
some storyboard magic.
Do you mean I have to subclass it to MyRootNavigationController, which only
implements supportedInterfaceOrientations?
No. Better give it a delegate, which implements
navigationControllerSupportedInterfaceOrientations:
Easier said than done though.
The Main.storyboard contains a "Navigation Controller Scene", but no
AppDelegate. How should I set this to be the delegate also of the
NavigationController?
Creating a class MyNavigationDelegate just for one method seems a bit silly.
Just did:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSArray *allWindows = application.windows;
if ( [ allWindows count ] != 1 ) // warn
{
NSLog(@"%s Warning: have %lu windows (should have
1)",__FUNCTION__,[ allWindows count ]);
};
UIWindow *someRandomWindow = allWindows.firstObject;
UINavigationController *rootViewController =
(UINavigationController*)someRandomWindow.rootViewController;
if ( ![ rootViewController isKindOfClass: [ UINavigationController
class ] ] ) // error
{
NSLog(@"%s Error bad class rootViewController
%@",__FUNCTION__,rootViewController);
return YES;
};
if ( rootViewController.delegate != nil ) // error
{
NSLog(@"%s Error rootViewController already has delegate
%@",__FUNCTION__,rootViewController.delegate );
return YES;
};
rootViewController.delegate = self;
return YES;
}
This seems to work, but it really looks like a very bad hack.
There sure must be a better solution.
Kind regards,
Gerriet.
