Unleash Your Inner App Developer Part 16: Tuning Up Core Data

image

Do you have an idea for an app but lack the programming knowledge to begin building it? In this weekly blog series, How to Unleash Your Inner App Developer, I will take you, the non-programmer, step by step through the process of creating apps for the iPhone, iPod touch, and iPad. Join me each week on this adventure, and you will experience how much fun turning your ideas into reality can be! This is Part 16 of the series. If you are just getting started now, check out the beginning of the series here(This post has been updated to iOS 7.1.)

In my previous blog post, you learned how to add Core Data to a project and how to design entities in a data model. In this post, you will learn how to generate entity classes from the entities in a data model and use them within your app. You can get the latest version of the iAppsReview project at this link.

In my previous post in this series, I discussed some of the basics of Core Data, the technology that allows you to store and retrieve information on an iOS device. You learned about entity data models, databases, and how you can improve on Apple's default Core Data implementation.

Core Data is the technology that allows you to store and retrieve information on an iOS device. Although it is an advanced technology often difficult to grasp, my goal in this post is to simplify Core Data so it can be easily used by beginners.

This post contains some of the most important information you need to know to build a well-designed app that easily adapts to changes requested by users, the constant changes Apple makes to iOS, and the ever-changing landscape of iOS devices. It all comes down to a solid app architecture. We're going to take a quick digression from the iAppsReview app this week to look at a simpler Calculator app to help us establish good architectural principles.

One of the best software development books of all time is Steve McConnell's Code Complete. Whether you are a seasoned software developer or a brand new programmer, regardless of the platform or language in which you write code, I highly recommend checking out this book. It will change your way of thinking and vastly improve the quality of the code you write.



Swift 101 - Swift Meets the Cocoa Touch Framework

image

Even though Apple has provided the new Swift programming language for building iOS apps, one thing remains the same—we still use the Cocoa Touch Framework libraries to build iOS functionality into our apps. However, since the Cocoa Touch Framework is written in Objective-C, how is this accomplished? In this article I'll show you the mechanics behind how Swift accesses Objective-C code, and how the Cocoa Touch APIs (application programming interfaces) change when you access them from Swift.

Now that you have some of the basics of Objective-C programming under your belt, it's time to dive into some deeper coding territory. However, first let's talk about the homework assignment I gave you last week. I asked you to enhance iAppsReview so that it pulled the name of the app from the Write Review scene's text field.

In my previous post, you learned the basic mechanics of sending messages. There's very little you can do in Objective-C, the language of iOS development, without sending messages. In this post, we're going to put into practice what you have learned about messages and integrate social media into the iAppsReview app we've been working on in this blog. I'm also going to introduce a new Cocoa Touch Framework concept known as collections. You can get the latest version of iAppsReview from this link.

In my previous post, I taught you how to write your very first line of code. In the process, I touched on the concept of passing messages in Objective-C. In this post, we're going to take a closer look at the important concept of passing messages, and we will also work on converting the prototype iAppsReview into a fully-functional app.

In my previous post, I mentioned Objective-C, the language of iOS Apps, is an object-oriented programming language. This means when you write code, you are mostly interacting with objects—both visual and non-visual. Working with an object-oriented language is a great advantage for non-programmers who want to learn programming. In this post I'll talk about these advantages, and we'll even get you to write your first lines of code!
