I want to make a UIButton
disable for user touch. Both setEnabled
and setUserInteractionEnabled
can do this. Which is better? How are they different?
enabled
is a property of UIControl
, which is the superclass for UIButton
. userInteractionEnabled
is a property of UIView
(which is the superclass of UIControl
). enabled
has effects on the visual state of the object (grayed out, by default) and is generally the preferred method of disabling a control—visual feedback indicating behaviors is a good thing.
There's not much practical upshot beyond that. Code that interacts with your controls is more likely to check if buttons are enabled than if their userInteractionEnabled property is set. Hence using enabled
is more conventional.
