🎈FloatingShowable

This is a support kit that helps you develop a picture-in-picture-like view.

Introduction

FloatingShowable is a UIKit library for a more concise picture-in-picture implementation. Acceleration control, which tends to be complicated, is also supported.

Features:

It was developed inspired by the picture-in-picture introduced in iOS14.
Movement that takes acceleration into account is possible
Various parameters related to shadow and movement animation can be customized
With this, picture-in-picture will be available in the app even on devices with iOS13 or lower.

Installation

CocoaPods

# Podfile
use_frameworks!

target 'YOUR_TARGET_NAME' do
    pod 'FloatingShowable'
end

Replace YOUR_TARGET_NAME and then, in the Podfile directory, type:

$ pod install

Carthage

Add this to Cartfile.

# Cartfile
github "AkkeyLab/FloatingShowable"

Run this script to install it.

$ carthage update --platform iOS

Simplest Usage

Please import FloatingShowable
The target UIViewController must be FloatingShowable compliant

import FloatingShowable
import UIKit

final class FloatingViewController: UIViewController, FloatingShowable {
    var position: FloatingPosition = .bottomRight

    var frameSize: CGSize {
        CGSize(width: 160, height: 90)
    }

    var window: UIWindow {
        UIApplication.shared.windows.filter { $0.isKeyWindow }.first ?? UIWindow()
    }
}

Call the show function from a FloatingShowable compliant object
Don't forget to call dismiss function when you want to destroy the parent instance

final class ViewController: UIViewController {
    private var floatingScreen = FloatingViewController()

    deinit {
        floatingScreen.dismiss(isScaleChange: true)
    }

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

        floatingScreen.show()
    }
}

For the simplest implementation, picture-in-picture can be achieved in just four steps.

Change the movement range

Change stayArea value
Call updateLayout function when the target object is already displayed

final class ViewController: UIViewController {
    private var floatingScreen = FloatingViewController()
    private var isBottomInsetAdd = false {
        didSet {
            floatingScreen.stayArea.bottom = isBottomInsetAdd ? 100 : 16
            floatingScreen.updateLayout()
        }
    }
}

After changing the value, if the target object is in the no-entry area, it will move with animation.
