iOS: tell UIKit when unlockOrientation() changes the supported mask (#6089) by shai-almog · Pull Request #6093 · codenameone/CodenameOne

shai-almog · 2026-10-24T03:10:40Z

unlockOrientation() only reset orientationLock. Since iOS 16 UIKit caches the root controller's supportedInterfaceOrientations and re-reads it only when asked, so after a lock (here, one held across the native camera as a workaround for #6080) autorotation stayed off until the app was restarted.

Fix

On the main queue, unlock now calls setNeedsUpdateOfSupportedInterfaceOrientations on the root controller. When no native modal is presented, it also asks the window scene to rotate to the physical device orientation, provided both the controller and the app allow it. Before iOS 16 it calls attemptRotationToDeviceOrientation. While a modal is up, only the invalidation is sent: the modal owns the orientation, and UIKit re-reads the root mask when the modal is dismissed.

Test

No automated test. A simulator can't physically rotate after an unlock, so the existing NativeModalRotationTest path can't observe this. It needs a check on a physical device using the reproducer attached to #6089.

ParparVM vs HotSpot (JDK 25): macOS arm64

Runner CPU: Apple M1 (Virtual) (baseline macos-arm64)

Ratios are ParparVM / JDK 25: below 1.00x ParparVM is faster (time) or smaller (RAM). Median of 5 interleaved, paired rounds; every run's output was verified. A ratio more than 20% (time) / 25% (RAM) above its baseline in vm/selfhost/perf-baseline/ is a regression and fails; one that far below is an improvement, reported but not failed (a row whose calibration runs were noisier carries a wider tolerance), and for RAM the change must also exceed 0.05x in absolute terms. Both run unpinned on all of the runner's CPUs, with their own default thread counts.
