How langshiyunyi/dynamicislandtweak works
DynamicIslandTweak is a jailbroken-iOS SpringBoard tweak that overlays a Dynamic Island-style view for now-playing media and notification banners. Its main flow is platform media/notification events into the Logos hook, through the display manager’s priority and timer state, and into the overlay UI; user gestures travel back through the manager for playback and dismissal actions. A separate Settings preference bundle saves configuration and signals live reloads. The README documents additional UI states, media controls, localization, and preference options; wiring details not shown in sampled source are limited to documented relationships.
