UIButton is a subclass of UIView for displaying buttons in iOS. It implements the target action paradigm to send events to the controller layer.

A UIButton intercepts touch events and sends an action message to a target object when tapped. Methods for setting the target and action are inherited from UIControl (). This class provides methods for setting the title, image, and other appearance properties of a UIButton. By using these accessors, you can specify a different appearance for each button state:

  • UIControlStateNormal,
  • UIControlStateHighlighted,
  • UIControlStateDisabled,
  • UIControlStateSelected.
  • UIControlStateFocused.
