Type Method

animate(withDuration:animations:)

Animate changes to one or more views using the specified duration.

Declaration

class func animate(withDuration duration: TimeInterval, animations: @escaping () -> Void)

Parameters

duration

The total duration of the animations, measured in seconds. If you specify a negative value or 0, the changes are made without animating them.

animations

A block object containing the changes to commit to the views. This is where you programmatically change any animatable properties of the views in your view hierarchy. This block takes no parameters and has no return value. This parameter must not be NULL.

Discussion

This method performs the specified animations immediately using the curveEaseInOut and transitionNone animation options.

During an animation, user interactions are temporarily disabled for the views being animated. (Prior to iOS 5, user interactions are disabled for the entire application.)
