> CDVViewController.supportedOrientations not set in a timely fashion
> -------------------------------------------------------------------
>
> Key: CB-1209
> URL: https://issues.apache.org/jira/browse/CB-1209
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Affects Versions: 2.0.0
> Environment: Mac OS X Lion, Xcode 4.4, iOS SDK 5.1
> Reporter: Kevin Hawkins
> Assignee: Shazron Abdullah
> Fix For: 2.1.0
>
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> The iOS template app (reasonably) expects to be able to access its
> viewController's `supportedOrientations` property to process the app's
> supported orientations, in `application:didFinishLaunchingWithOptions:`.
> However, supportedOrientations is not set until `CDVViewController`'s
> `viewDidLoad` method, which isn't called until the window is made visible.
> This trickles down into the status bar being forced into a state of
> `UIDeviceOrientationUnknown` by the forceStartupRotation functionality in the
> app delegate.
> What's more, when the status bar orientation is forced by setting
> UIApplication's statusBarOrientation property explicitly, it will no longer
> adhere to any autorotation behavior. This means that the status bar is
> permanently set into an unknown state, which basically impacts the main view
> size, since [[UIScreen mainScreen] applicationFrame] assumes an unknown state
> means that it gets the whole device frame for its area.
> Making the window visible before testing the orientations is a workaround,
> but arguably the initial setting of the supportedOrientations property should
> happen outside of the view lifecycle (i.e. in the `init` functionality of
> CDVViewController), since it has no dependency on any UI state--it reads
> `UISupportedInterfaceOrientations` configuration data from the app bundle to
> determine valid orientations.
