FloatingView

A library for injecting and managing a floating view in the navigation controller view hierarchy.

Features

This library lets you add a floating view at the navigation controller level

• ❌ No need to subclass your nav controller
• ❌ No view logic in your nav controller
• ✅ Customization hooks whenever a view controller is shown

Usage

Setup

let floatingButton = ...
let floatingViewManager = FloatingViewManager(floatingView: floatingButton)
let nav = UINavigationController(rootViewController: vc, floatingViewManager: floatingViewManager)

Customization

Customization is offered via the FloatingViewCustomizing protocol.

protocol FloatingViewCustomizing {
    func shouldShowButton() -> Bool
    func createConstraints(floatingView: UIView, superview: UIView)
}

For each hook offered through the protocol, customization can be done with the following order of precendence:

• view controller being shown can conform to FloatingViewCustomizing and implement methods
• navigation controller can conform to FloatingViewCustomizing and implement methods
• default handler property corresponding to the desired customization can be set on the manager
