Usage

The Versions File

You’ll need to host a JSON file on a server somewhere that defines options like whether or not an update is required,
recommended or not necessary.

The file also defines the messaging to be displayed in each case. For example, if the user has version 1.0 installed
(and the file below is used), when the you call Retire.check the supplied message in the completion block will be
the forced one.

If they’re running 1.1, you’d get the recommended message, and if they’re running 2.0 no update would be required.

Here’s an example of a versions file:

{
  "messaging": {
    "forced": {
      "title": "App Update Required",
      "message": "A new version of the app is available. You need to update now",
      "continueButtonText": "Let's do this"
    },
    "recommended": {
      "title": "App Update Available",
      "message": "A new version is available. Want it?",
      "continueButtonText": "I want it",
      "cancelButtonText": "No thanks"
    }
  },
  "versions": [
    { "version": "1.0", "policy": "force" },
    { "version": "1.1", "policy": "recommend" },
    { "version": "2.0", "policy": "none" }
  ]
}

There are two types of objects here; message and version.

message

  • title – The title of the alert (e.g. New Version Available)
  • message – The message to be displayed (e.g. There’s a new version available)
  • continueButtonText – The label for the button that links to the app store
  • cancelButtonText – The (optional) label for the cancel button (intended for recommended updates only)

version

  • version – The version of the app (pulled from CFBundleShortVersionString)
  • policy – One of force, recommend or none

Checking Status in Your App

I don’t wanna tell you how to handle displaying alerts or anything, but here’s what I did in the example app (if you
open the workspace you’ll see it in AppDelegate.swift).

First, I made an extension on Message

extension Message {
  func presentInController(controller: UIViewController?) {
    let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
    alert.addAction(UIAlertAction(title: continueButtonText, style: .Default, handler: goToAppStore))

    if cancelButtonText != nil {
      alert.addAction(UIAlertAction(title: cancelButtonText, style: .Cancel, handler: nil))
    }

    controller?.presentViewController(alert, animated: true, completion: nil)
  }

  private func goToAppStore(action: UIAlertAction) {
    UIApplication.sharedApplication().openURL(iTunesURL)
  }
}

Then, in applicationDidFinishLaunching:withOptions, I configured Retired with the URL to the versions file:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
  let versionURL              = NSURL(string: "https://example.com/versions.json")!
  let intervalBetweenRequests = 60 * 60 * 24 // one day between recommended app updates

  Retired.configure(versionURL, suppressionInterval: intervalBetweenRequests)
  return true
}

Finally, in applicationDidBecomeActive, I query the status and show a message if necessary:

func applicationDidBecomeActive(application: UIApplication) {
  // you should catch the error in production apps
  try! Retired.check() { updateRequired, message, error in
    guard updateRequired else { return }

    // handle error (non 200 status or network issue)

    if let message = message {
      message.presentInController(application.keyWindow?.rootViewController)
    }
  }
}
