Sandbox: initiate a Newsstand background download more than once in a 24-hour period


The content of my publication needs to be updated throughout the day. Can I initiate a Newsstand background download more than once in a 24-hour period?

Allowing multiple background downloads for multiple apps would drain system resources, so Newsstand apps are limited to one background download initiated by push notification each day. If you send additional notifications to a device that attempt to initiate a background download, those notifications will be delivered to the device but ignored by Newsstand Kit.

If you want your Newsstand app to deliver breaking news, consider sending an issue via background download and downloading a small amount of additional, up-to-the-minute content when the user launches your app.

For test purposes on development devices only, you can override the built-in limit and initiate more than one background download in a 24-hour period by setting the user default @"NKDontThrottleNewsstandContentNotifications". See Listing 1.

[[NSUserDefaults standardUserDefaults]setBool: YES forKey:@"NKDontThrottleNewsstandContentNotifications"];

Pattern: Riblets vs. VIPER

Engineering the architecture behind Uber's new rider app

Not being held back by our extensive codebase and previous design choices gave us the freedom where we otherwise would have made compromises. The outcome is the sleek new app you see today, which implements a new mobile architecture across both iOS and Android. Read on to learn why we felt the need to create this new architecture pattern, called Riblets, and how it helps us reach our goals.

The platforms share:

Core architectureClass namesInheritance relationships between business logic unitsHow business logic is dividedPlugin points (names, existence, structure, etc.)Reactive programming chainsUnified platform components
Each Riblet is made up of one Router, Interactor, and Builder with its Component (hence the name), and optional Presenters and Views. The Router and Interactor handle the business logic, while the Presenter and View handle the view logic.

WireMock

WireMock is a flexible library for stubbing and mocking web services. Unlike general purpose mocking tools it works by creating an actual HTTP server that your code under test can connect to as it would a real web service.

It supports HTTP response stubbing, request verification, proxy/intercept, record/playback of stubs and fault injection, and can be used from within a unit test or deployed into a test environment.

Although it’s written in Java, there’s also a JSON API so you can use it with pretty much any language out there.
