Example code

import Massive

...

MSVInit(apiToken: apiToken, completion: { (massive: MSVNode?, error: Error?) -> Void in
  if massive != nil {
    massive.userOptedIn = true

    massive.menuBarUsageShown = true

    if massive.menuBarUsageShown {
      massive.menuBarUsageShown = false
    }

    let massiveViewController = massive.createUsageViewController()
    view.addSubview(massiveViewController.view)

    massive.pauseUsage(timePeriod: .hour)

    if massive.usagePaused {
      massive.unpauseUsage()
    }

    if massive.userOptedIn {
      massive.userOptedIn = false
    }
  }
} as! MSVInitCompletionHandler)

​
Getting started

  1. Download the latest SDK package.
  2. Open the Xcode project you want to integrate the SDK into.
  3. If your project navigator isn’t shown, go to View > Navigators > Show Project Navigator.
  4. Open the SDK package and drag the Massive.framework bundle into the navigator.
  5. If the Copy items if needed box and box for your app target aren’t checked, check them.
  6. Press the Finish button.
  7. In the implementation file for your app delegate, import the SDK: 
    // Importing in Swift:
import Massive
  8. In your applicationDidFinishLaunching method, start and wait till the SDK is ready by calling the MSVInit function and defining a MSVInitCompletionHandler block: 
    // Starting in Swift:
func applicationDidFinishLaunching(_ notification: Notification) {
  ...

  MSVInit(apiToken: apiToken, completion: { (massive: MSVNode?, error: Error?) -> Void in
    if massive != nil {
      ...
    }
  } as! MSVInitCompletionHandler)

  ...
}
  9. When the user opts in, toggle the userOptedIn property on: 
    // Opting in in Swift:
massive.userOptedIn = true
  10. Next, show user tooling by toggling the menuBarUsageShown property on on demand or calling the getUsageViewController method then adding the view of the returned controller to your interface: 
    // Showing system tooling in Swift:
massive.menuBarUsageShown = true

// Showing custom tooling in Swift:
let massiveViewController = massive.createUsageViewController()
view.addSubview(massiveViewController.view)
See the API reference for detailed info and optional SDK functionality.

API reference

​
Protocol

MSVNode Defines a node of the Massive distributed computer.

​
Types

typealias MSVInitCompletionHandler = (MSVNode?, Error?) -> Void A block called asynchronously after a Massive node has been started. The node, if started successfully, or startup error, if not, is passed to the block.
enum MSVTimePeriod: Int A capped or uncapped duration. Cases case indefinite An indefinite time period. case hour An hour. case day A day. case week A week.

​
Functions

func MSVInit(apiToken: String, completion: MSVInitCompletionHandler) Starts a Massive node, pending user opt-in, attributed to your API token. Parameters apiToken A unique developer identifier obtained from this website. completion A block called asynchronously after node startup.

​
Properties

var userOptedIn: Bool { get set } The state of user opt-in. true allows computing resources to be opportunistically consumed; false doesn’t. Resource consumption is disallowed by default; the user must agree to easy-to-understand terms of the exchange you’re offering before you toggle this property on.
var usagePaused: Bool { get } The enablement state of resource consumption. true indicates usage is paused; false, unpaused.
var menuBarUsageShown: Bool { get set } The visibility state of menu-bar tooling. true adds charts representing resource consumption to the user’s menu bar; false removes them. Resource charts aren’t made available by default; they must be added to the menu bar by toggling this property on or to your interface by calling the createUsageViewController method.

​
Methods

func pauseUsage(timePeriod: MSVTimePeriod) Disables opportunistic resource consumption for the finite time period or till you call the unpauseUsage method. Resource consumption is enabled by default. Parameters timePeriod A capped or uncapped duration.
func unpauseUsage() Re-enables resource consumption if disabled.
func createUsageViewController() -> NSViewController Constructs a view controller with charts representing resource consumption that you can add to your app’s interface. Resource charts must be added to your interface by calling this method or to the menu bar by toggling the menuBarUsageShown property on. Return value The view controller with resource charts.
