- Modal presentations can be programmatic or implemented using segues.
- Transition direction and speed is customizable.
- Designed for portrait device orientation.
- Swift 3.0
Demo
Requirements
- iOS 8.0+
- Xcode 10.0+
Usage
Installation
pod "FlipTheBlinds"
Modal Presentations
- Assign the
transitioningDelegateproperty of the view controller being presented to the presenting view controller. - Add an extension to the presenting view controller that includes methods for the
UIViewControllerTransitioningDelegate. - Return instances of the
FTBAnimationControlleranimator object usingFTBAnimationController(displayType:direction:speed:)for presenting and dismissing.
// MARK: Programmatic option
func presentAction() {
let toViewController = ToViewController()
toViewController.transitioningDelegate = self
self.present(toViewController, animated: true, completion: nil)
}
// MARK: Segue option
func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "segue", let destinationViewController = segue.destination as? toViewController {
destinationViewController.transitioningDelegate = self
}
}
// MARK: Transitioning Delegate
extension fromViewController: UIViewControllerTransitioningDelegate {
func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return FTBAnimationController(displayType: .present, direction: .up, speed: .moderate)
}
func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return FTBAnimationController(displayType: .dismiss, direction: .down, speed: .moderate)
}
}Navigation
- Assign the
delegateproperty of the navigation controller to the root view controller. - Add an extension to the root view controller that includes the
UINavigationControllerDelegateand necessary transitioning method. - Return instances of the
FTBAnimationControlleranimator object usingFTBAnimationController(displayType:direction:speed:)for push and pop.
// MARK: Push
func pushAction() {
let navStackViewController = NavStackViewController()
self.navigationController?.delegate = self
self.navigationController?.pushViewController(navStackViewController, animated: true)
}
// MARK: Navigation Controller Delegate
extension NavRootViewController: UINavigationControllerDelegate {
func navigationController(_ navigationController: UINavigationController, animationControllerFor operation: UINavigationControllerOperation, from fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
switch operation {
case .pop:
return FTBAnimationController(displayType: .pop, direction: .right, speed: .moderate)
case .push:
return FTBAnimationController(displayType: .push, direction: .left, speed: .moderate)
default:
return nil
}
}
}Tab Bar
- Assign the
delegateproperty of the tab bar controller to one of the root view controllers of the tab bar controller. - Add an extension to a root view controller that includes the
UITabBarControllerDelegateand necessary transitioning method. - Return an instance of the
FTBAnimationControlleranimator object usingFTBAnimationController(displayType:direction:speed:).
// MARK: Delegate
override func viewDidLoad() {
super.viewDidLoad()
self.tabBarController?.delegate = self
}
// MARK: Tab Bar Controller Delegate
extension TabBarRootOneViewController: UITabBarControllerDelegate {
func tabBarController(_ tabBarController: UITabBarController, animationControllerForTransitionFrom fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return FTBAnimationController(displayType: .tabSelected, direction: .down, speed: .moderate)
}
}Known Issues
- Drawing/Rendering images in the animator object is problematic for the simulator, especially iPhone 7/7P. Device testing is recommended.
-
drawHierarchy(in:afterScreenUpdates:)is used for modal presentations and may cause an inconspicuous flicker.
