Programming iOS Applications
Do you have any knowledge of computer programming? Then this iOS development guide may be hard for you to understand. To learn if you know what is what in software programming, take a look at the following terms and explanations:
- Function — var name = Mary.getName();
- Variable — var x = 7;
- Array — var things = array("good", "bad");
- Conditional — if (x == 25).
The Basics of Coding
These are general computer programming terms utilised in JavaScript, one of the leading programming languages, so if you feel confused about what you have just seen, head directly to any JavaScript manual and scan through the basics. Another cornerstone of computer programming is C, so you have no idea what is a struct and what is a header file, our experts advise you to take a look into a C programming language tutorial and return to this article when you grasp the basic concepts of the language. When this is done, let us give you an insight into Objective-C.

Objective-C
>
Objective-C is the primary language for iOS native app development. Needless to say, there are dozens of languages you can write iOS app in, including pure C, C++, PyObjC, MacRuby, MonoTouch and much more, but we will not go into detail about them, you can find more info in the internet, if you are interested. If you do not want to use any of the languages mentioned above you can create a non-native app with the use of an app-building platform or build a web-based application, which is a website that looks like an application loaded in a mobile browser. Web-based apps are built on the basis of web technologies and languages like HTML5, JavaScript and CSS.
Characteristics of Objective-C

If you want to create a web-based app or a mobile website, there is no need to learn Objective-C, iOS development environments or any guides on app developer like this one. However, if your goal is to design a native application for iPhone, iPad or Mac, this article can be of a great help. Objective-C is an object-oriented programming language that is basically an addition to the C programming language. It adds Smalltalk-style messaging, inheritance, reflection and other crucial aspects to C. If you know Ruby or java, Objective-C’s syntax may seem confusing at first, but do not be afraid, you will get used to it. Because Objective-C is an extension of C, you can always get back to C in your code whenever you feel like it. Many iOS apps utilise primitive C data types and native C functions along with Objective-C functions and data types.
Build Your First iOS App
>
Now that you know the essential tools and the basics of Objective-C, do not waste time - launch Xcode and start building your first iOS app. There you will see a project waiting for you with some pre-made key files. One of the files is an app delegate, which determines the main setup of the application. You will see the line that says application: didFinishLaunchingWithOptions:, and that is where your app begins. That is where you first code will start, your user interface will be built and your first model objects will be created and utilised.
