iOS 7 SDK: Working with Background Fetch

iOS 7 SDK: Working with Background Fetch | iPhone and iPad Development | Scoop.it

This tutorial will teach you how to use Background Fetch, a multitasking API provided with the iOS 7 SDK. To do so, we'll create a simple list of delicious dishes that are automatically fetched in the background. Read on!

Project Overview

Background Fetch is an awesome feature released with iOS 7. Today, we live in a social world, and most of our users have several social network apps on their mobile devices. However, every time the user opens each app, they typically must wait until the app updates to view more recent content. This can be painful if several apps and profiles are used. Now, with background fetch, all content can be automatically fetched and updated before the user loads the app.

The default Traffic application is a simple example of how Background Fetch works in action. If you check it every morning, let’s say at 8:20 AM, your iOS app must get that information at that time. Now, if the operating system knows you will access the app around 8:20 AM, it can fetch the data beforehand and have it ready when desired.

For a more comprehensive overview of the new multitasking features, be sure to read our introduction to this topic. The rest of this tutorial will be dedicated to a practical project that demonstrates how to implement Background Fetch.

Animation: Matrix Transformations

Animation. Such a powerful word when used in the context of UI programming. The tools provided by the Cocoa Touch frameworks allow developers to add dynamic, fluid animations to their app, often with only a few lines of code. Matrix transformations serve as one such tool, allowing you to scale, translate, and rotate views in any way imaginable (provided you know the math to make it possible). These transformations can be used to add that needed polish to the UI of your app by animating view transitions or providing feedback to user interaction.

nil / Nil / NULL / NSNull: Understanding the concept

nil / Nil / NULL / NSNull: Understanding the concept | iPhone and iPad Development | Scoop.it

Understanding the concept of nothingness is as much a philosophical issue as it is a pragmatic one. We are inhabitants of a universe of _somethings_, yet reason in a logical universe of existential uncertainties.

We've talked before about the philosophical and technical concerns of nothingness in programming. This week, our attention turns to another fundamental matter: Truth.
