TabBarAnimationDelegate

open class TabBarAnimationDelegate : NSObject

TabBarAnimationDelegate is used as the delegate of a TabBarCoordinator’s rootViewController to allow for transitions to specify transition animations.

TabBarAnimationDelegate conforms to the UITabBarControllerDelegate protocol and is intended for use as the delegate of one tabbar controller only.

Note

Do not override the delegate of a TabBarCoordinator’s rootViewController-delegate. Instead use the delegate property of the TabBarCoordinator itself.
