Event Delivery in iOS
summary
Shows the actual event pipeline: hit testing walks the window down the view tree, touchesBegan bubbles back up through views, view controllers, window and app delegate; UIControl sendAction:to:from:forEvent: is used rather than direct callbacks; gesture recognizers can short‑circuit touches; a demo uses becomeFirstResponder and key commands to switch who handles keys; a table cell creates a custom event sent up the responder chain to set the navigation title and the approach works though first‑responder timing can be surprising.
