Answer from AI
The main stages of the UIView lifecycle in iOS are related to its creation, display, and removal:
-
Initialization: creating a UIView instance via
init(frame:)or loading from XIB/Storyboard. -
Loading and setup: configuring properties, adding subviews.
-
Adding to hierarchy: calling
addSubview(_:), after which the UIView becomes part of the hierarchy. -
Layout: calling
layoutSubviewsmethods to position and resize subviews. -
Drawing: the
draw(_:)method is called for custom drawing. -
Event handling: UIView can handle touches and gestures.
-
Removal: when removed from the hierarchy,
removeFromSuperview()is called, after which the object can be deallocated.
These stages ensure the correct creation, display, and interaction of UIView in an application.
