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 & 5.0. Ready for use on iOS 10+
You can use CocoaPods to install SPStorkController by adding it to your Podfile:
pod 'SPStorkController'You can use Carthage to install SPStorkController by adding it to your Cartfile:
github "IvanVorobei/SPStorkController"
For now Carthage support may not work correctly. If you have any problems, create a new issue.
Put Source/SPStorkController folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.
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
customHeightsets custom height for modal controller. Default isnil:
transitionDelegate.customHeight = 350- Parameter
swipeToDismissEnabledenables dismissal by swipe gesture. Default istrue:
transitionDelegate.swipeToDismissEnabled = true- Parameter
translateForDismisssets how much need to swipe down to close the controller. Work only ifswipeToDismissEnabledis true. Default is240:
transitionDelegate.translateForDismiss = 100- Parameter
tapAroundToDismissEnabledenables dismissal by tapping parent controller. Default istrue:
transitionDelegate.tapAroundToDismissEnabled = true- Parameter
showCloseButtonadded circle button with dismiss action. Default isfalse:
transitionDelegate.showCloseButton = false- Parameter
showIndicatorshows or hides top arrow indicator. Default istrue:
transitionDelegate.showIndicator = true- Parameter
indicatorColorfor customize color of arrow. Default isgray:
transitionDelegate.indicatorColor = UIColor.white- Parameter
hideIndicatorWhenScrollshows or hides indicator when scrolling. Default isfalse:
transitionDelegate.hideIndicatorWhenScroll = true- Parameter
cornerRadiusfor customize corner radius of controller's view. Default is10:
transitionDelegate.cornerRadius = 10- Parameter
hapticMomentsallow add taptic feedback for some moments. Default is.willDismissIfRelease:
transitionDelegate.hapticMoments = [.willPresent, .willDismiss]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.heightPlease, 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 = selfIf you want to present modal controller on SPStorkController, please set:
controller.modalPresentationStyle = .customIt’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!
