Intro

ReachabilityUI is a framework meant to help informing the user when an app loses connection to the internet.

With ReachabilityUI you can even register a ReachabilityListener instance that will allow you to get notified about the connection drop. This can be used to adjust your application's UI so that the content won't overlap the banner, or for any other action you might need to take when the connectivity drops.

Please refer to the demo project for a showcase on how to integrate the ReachabilityUI framework in a Nodes like VIPER architecture.

📝 Requirements

  • iOS 11
  • Swift 4.0+

📦 Installation

Carthage

github "nodes-ios/Reachability-UI"

Cocoapods

pod "ReachabilityUI"

💻 Usage

Initialize the ReachabilityUI Dependencies

Conform to HasReachabilityListenerRepository and create a ReachabilityUIManager instance:

import UIKit
import ReachabilityUI

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    public var reachabilityListenerFactory: ReachabilityListenerFactoryProtocol!

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        reachabilityListenerFactory = ReachabilityUIManager()

        return true
    }
}

extension AppDelegate: HasReachabilityListenerRepository {}

Initialize the ReachabilityUI Banner

To enable the Reachability banner in your views, add the following code snippet to your AppDelegate.swift:

private func addReachability() {
    // create a ReachabilityConfiguration instance  
    let configuration = ReachabilityConfiguration(title: "Connected",
                                                  noConnectionTitle: "No Connection",
                                                  options: nil)

    // create the ReachabilityCoordinator and pass it along the previously
    // created ReachabilityConfiguration together with the ReachabilityListenerFactoryProtocol
    let coordinator = ReachabilityCoordinator(
        window: window,
        reachabilityListenerFactory: reachabilityListenerFactory,
        configuration: configuration
    )
    reachabilityCoordinator = coordinator
    coordinator.start()
}

Listen for Reachability Changes

To get notified about connectivity changes you must create a listener and start listening in order to get notified about the connectivity changes.

private var listener: ReachabilityListenerProtocol!

func subscribe() {
    listener = reachabilityListenerFactory.makeListener()
    listener.listen { [weak self] (isConnected) in
        // TODO: react to change in connected state
    }
}

Change Configurations

You can change the various options in the ReachabilityConfiguration to tailor the component to your needs.

 let configuration = ReachabilityConfiguration(title: "Connected",
                                               noConnectionTitle: "No Connection",
                                               options: [.appearance : ReachabilityConfiguration.Appearance.bottom,
                                                         .appearanceAdjustment : CGFloat(-100),
                                                         .animation : ReachabilityConfiguration.Animation.slideAndFadeInOutFromBottom])

The following keys can be used in the options dictionary:

  • .titleColor (must be a UIColor)
  • .noConnectionTitleColor (must be a UIColor)
  • .noConnectionBackgroundColor (must be a UIColor)
  • .backgroundColor (must be a UIColor)
  • .height (must be a CGFloat)
  • .font (must be a UIFont)
  • .textAlignment (must be a NSTextAlignment)
  • .animation (must be a ReachabilityConfiguration.Animation)
  • .appearance (must be a ReachabilityConfiguration.Appearance)
  • .appearanceAdjustment (must be a CGFloat)

If options are set to nil, default options will be used. Any options set, will override the default state.
