AnimationSwitchingTabBar
Overview
AnimationSwitchingTabBar is an animatable tab bar class in Swift. This project is inspired by the dribble project.
Usage
Basic
Define a tab view controller
Inherit AnimationSwitchingTabBarController . And set child view controllers.
class TabViewController: AnimationSwitchingTabBarController {
override func viewDidLoad() {
super.viewDidLoad()
let vc1: AnimationSwitchingViewController = ...
let vc2: AnimationSwitchingViewController = ...
let vc3: AnimationSwitchingViewController = ...
setViewControllers([vc1, vc2, vc3])
}
}Define child view controllers
Inherit AnimationSwitchingViewController . And set an icon image.
class Child1ViewController: AnimationSwitchingViewController {
override func viewDidLoad() {
super.viewDidLoad()
setIcon(image: UIImage(named: "SearchIcon"))
}
}Implement delegate
extension TabViewController: AnimationSwitchingTabBarControllerDelegate {
override func tabBarController(_ tabBarController: AnimationSwitchingTabBarController,
shouldSelect viewController: UIViewController) -> Bool {
return true
}
override func tabBarController(_ tabBarController: AnimationSwitchingTabBarController,
didSelect viewController: UIViewController) {
// Called when an tab bar controller selected the child view controller.
}
}Others
Set animatable icon
Define custom item class. And, configure constraints and an animation.
class CustomAnimatableItem: AnimationSwitchingTabBarItem {
override func animate() {
super.animate()
// Define the item's animation to start.
}
override func setNotSelectedItem() {
super.setNotSelectedItem()
// Define constraints if the item is not selected.
}
override func setSelectedItem() {
super.setNotSelectedItem()
// Define constraints if the item is selected.
}
