Requirements

Swift 4.2 & 5.0. Ready for use on iOS 10+

Installation

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

To integrate using Xcode 12, specify it in File > Swift Packages > Add Package Dependency...:

https://github.com/ivanvorobei/SPLarkController

CocoaPods:

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate using CocoaPods, specify it in your Podfile:

pod 'SPLarkController'

Manually

If you prefer not to use any of dependency managers, you can integrate manually. Put Sources/ProjectName folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.

Usage

Presenting

Create controller and call func presentAsLark:

import UIKit
import SPLarkController

class ViewController: UIViewController {
    
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)

        let controller = UIViewController()
        self.presentAsLark(controller)
    }
}

If you want customize controller (set custom height and other), create controller and set transitioningDelegate to SPLarkTransitioningDelegate object. Use present or dismiss functions:

let controller = UIViewController()
let transitionDelegate = SPLarkTransitioningDelegate()
controller.transitioningDelegate = transitionDelegate
controller.modalPresentationStyle = .custom
controller.modalPresentationCapturesStatusBarAppearance = true
self.present(controller, animated: true, completion: nil)

Please, do not init SPLarkTransitioningDelegate like this:

controller.transitioningDelegate = SPLarkTransitioningDelegate()

You will get an error about weak property.

Height

Parameter customHeight sets custom height for modal controller. Default is nil:

transitionDelegate.customHeight = 350

Change Height

For change height after presenting use with code:

if let presentationController = self.presentationController as? SPLarkPresentationController {
    presentationController.updateHeight(600)
}

You can see how it work in Example folder. I am plase ready-use project.

Settings Controller

You can simple implement settings controller as in preview. You need extend from SPLarkSettingsController and implement all methods for it. See class for more details.

class SettingsController: SPLarkSettingsController {}

Snapshots

The project uses a snapshot of the screen in order to avoid compatibility and customisation 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:

SPLarkController.updatePresentingController(modal: controller)

and pass the controller, which is modal and uses SPLarkTransitioningDelegate

Modal presentation of other controller

If you want to present modal controller on SPLarkController, please set:

controller.modalPresentationStyle = .custom

It’s needed for correct presentation and dismissal of all modal controllers.
