Modal controller like in Mail or Apple Music application. Similar animation and transition. I tried to recreate all the animations, corner radius and frames. Controller supports gestures and Navigation Bar and works with ScrollView. You can watch how to use pod tutorial on YouTube.

I have a store where I sell applications and modules for Xcode projects. You can find source codes of applications or custom animations / UI. I regularly update the code.

Swift 4.2. Ready for use on iOS 10+
Put Source/SPStorkController
folder in your Xcode project. Make sure to enable Copy items if needed
and Create groups
.
Or via CocoaPods:
pod 'SPStorkController'
Create controller and call func presentAsStork
:
import UIKit
import SPStorkController
class ViewController: UIViewController {
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let controller = UIViewController()
self.presentAsStork(controller)
}
}
If you want customize controller (remove indicator, set custom height and other), create controller and set transitioningDelegate
to SPStorkTransitioningDelegate
object. Use present
or dismiss
functions:
let controller = UIViewController()
let transitionDelegate = SPStorkTransitioningDelegate()
controller.transitioningDelegate = transitionDelegate
controller.modalPresentationStyle = .custom
controller.modalPresentationCapturesStatusBarAppearance = true
self.present(controller, animated: true, completion: nil)
Please, do not init SPStorkTransitioningDelegate
like this:
controller.transitioningDelegate = SPStorkTransitioningDelegate()
You will get an error about weak property.
You can see how to use SPStorkController
and how to customize it in this video. For English speakers I’ve added subtitles, don’t forget to turn them on:
On my YouTube channel you can find videos about Xcode and Design. I would appreciate it if you like and subscribe. If you do not want to watch the video, I wrote a small wiki below.
To set light
status bar for presented controller, use preferredStatusBarStyle
property. Also set modalPresentationCapturesStatusBarAppearance
. See example:
import UIKit
class ModalViewController: UIViewController {
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
}
- Parameter
customHeight
sets custom height for modal controller. Default isnil
:
transitionDelegate.customHeight = 350
- Parameter
swipeToDismissEnabled
enables dismissal by swipe gesture. Default istrue
:
transitionDelegate.swipeToDismissEnabled = true
- Parameter
translateForDismiss
sets how much need to swipe down to close the controller. Work only ifswipeToDismissEnabled
is true. Default is240
:
transitionDelegate.translateForDismiss = 100
- Parameter
tapAroundToDismissEnabled
enables dismissal by tapping parent controller. Default istrue
:
transitionDelegate.tapAroundToDismissEnabled = true
- Parameter
showCloseButton
added circle button with dismiss action. Default isfalse
:
transitionDelegate.showCloseButton = false
- Parameter
showIndicator
shows or hides top arrow indicator. Default istrue
:
transitionDelegate.showIndicator = true
- Parameter
indicatorColor
for customize color of arrow. Default isgray
:
transitionDelegate.indicatorColor = UIColor.white
- Parameter
hideIndicatorWhenScroll
shows or hides indicator when scrolling. Default isfalse
:
transitionDelegate.hideIndicatorWhenScroll = true
- Parameter
cornerRadius
for customize corner radius of controller's view. Default is10
:
transitionDelegate.cornerRadius = 10
The project uses a snapshot of the screen in order to avoid compatibility and customization issues. Before controller presentation, a snapshot of the parent view is made, and size and position are changed for the snapshot. Sometimes you will need to update the screenshot of the parent view, for that use static func:
SPStorkController.updatePresentingController(modal: controller)
and pass the controller, which is modal and uses SPStorkTransitioningDelegate
You may want to add a navigation bar to your modal controller. Since it became impossible to change or customize the native controller in swift 4 (I couldn’t even find a way to change the height of the bar), I had to recreate navigation bar from the ground up. Visually it looks real, but it doesn’t execute the necessary functions:
import UIKit
import SPFakeBar
class ModalController: UIViewController {
let navBar = SPFakeBarView(style: .stork)
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.white
self.navBar.titleLabel.text = "Title"
self.navBar.leftButton.setTitle("Cancel", for: .normal)
self.navBar.leftButton.addTarget(self, action: #selector(self.dismissAction), for: .touchUpInside)
self.view.addSubview(self.navBar)
}
}
You only need to add a navigation bar to the main view, it will automatically layout. Use style .stork
in init of SPFakeBarView
. Here is visual preview with Navigation Bar and without it:
To use SPFakeBarView
you need to install SPFakeBar pod:
pod 'SPFakeBar'
If you use UIScrollView
(or UITableView & UICollectionView) on your controller, I recommend making it more interactive. When scrolling reaches the top position, the controller will interactively drag down, simulating a closing animation. Also available close controller by drag down on UIScrollView
. To do this, set the delegate and in the function scrollViewDidScroll
call:
func scrollViewDidScroll(_ scrollView: UIScrollView) {
SPStorkController.scrollViewDidScroll(scrollView)
}
Working with a collections classes is not difficult. In the Example
folder you can find an implementation. However, I will give a couple of tips for making the table look better.
Firstly, if you use SPFakeBarView
, don't forget to set top insets for content & scroll indicator. Also, I recommend setting bottom insets (it optional):
tableView.contentInset.top = self.navBar.height
tableView.scrollIndicatorInsets.top = self.navBar.height
Please, also use SPStorkController.scrollViewDidScroll
function in scroll delegate for more interactiveness with your collection or table view.
You can check events by implement SPStorkControllerDelegate
and set delegate for transitionDelegate
:
transitionDelegate.storkDelegate = self
If you want to present modal controller on SPStorkController, please set:
controller.modalPresentationStyle = .custom
It’s needed for correct presentation and dismissal of all modal controllers.
Here I would like to offer you my other projects.
Project SPPermission for managing permissions with customizable visual effects. Beautiful dialog increases the chance of approval (which is important when we request notification). Simple control of this module saves you hours of development. You can start using project with just two lines of code and easy customization!
