10 things you need before writing Apple App

You've seen amazing statistics about Apple Apps and how ordinary people are successful writing apps for iPhone and iPad. Well, the first thing I can tell you is that you're right! Apple App Store is taking the world by storm (over more than 2 billion downloads). And my suspicion is that this is all just the beginning.

The problem is, how do you write an app? Indeed, what do you need before you develop an application? Well, that's where this article will help. I will provide you 10 items that you need before you start writing your apple apple. Even if you have never developed mobile content, or if you are new to software development, you should know that it can be fun and rewarding experience learning iPhone development.

1. Get Mac OS X Computer

To develop applications for iPhone OS, you need a Mac OS X computer to run the Xcode tool. Xcode is Apple's suite of development tools that support project management, code editing, building applications, and debugging.

I know that many of you could be a computer user. Some of you might be thinking about using a Mac. Well, my advice is – give your Mac a chance. I have many friends who were once dying-hard PC users who have now switched to Mac. Why? Because they want to write a program! And when they did the exchange – they found Mac to be so much easier to use and a very fun experience.

2. Download SDK

Apple distributes software development software for the iPhone app (SDK). You definitely need to download this and read it from the front page back. Do not worry, it's more complicated than it seems. Take time and you'll soon be on the programming car.

3. Learn Objective-C

Mac programs are written in Objective-C Apple also introduced a special Objective-C abstraction API called Cocoa Touch for iPhone (and iPod Touch) development.

Goal C will come very naturally to those who have programmed in C, C ++ or Java before. Now, if you're new to programming, Objective-C could be challenged.

Try to grab a basics of programming before you get a node and a ball in Objective-C. One of the better books to study Objective-C is Programming in Objective-C by Stephen G. Kochan. You are not expected to have any prior knowledge in this field.

4. Make an Authorized Apple Developer

Becoming an approved programmer for an Apple application takes some time. Many people do not know this. I hear it's a six-month waiting list to be a certified developer. Some have the idea that the time to wait can be reduced now when interest in the iPhone and iPad has landed in the roof around the world.

Becoming an approved developer will get you only in the App Store. Of course, it's the only way to spread your applications, so it's an essential part of that process.

5. Investigate your application

As with everything related to software development, the goal of your app will be a solution to the number of users.

Make sure you investigate your application. It's no use to just jump into writing programs that do not meet the needs of users. A year ago, you could easily write programs that made some nonsense (such as shooting noise) and expect people to download it. It will not happen anymore. If you want a popular application, you need to make it useful.

Usually, when you are developing a mobile phone, your audience is on the move. People who use mobile apps want quick communication. They do not want to write a Word document at all. They want to make useful things by just pressing a button or two.

The other tip I have is to think about Apple iPhone as a pocket computer. For example, well-behaved programs like Pandora have been most often fought in desktop mode as a wrap-up solution. When planning an application, think about what's unique for iPhone that can be used in your application.

6. Write for portability

What do I mean with portability? Well, depending on what frame (main features of the iPhone SDK) are used in your application, your application can not work on all iPhone devices. For example, an application that uses the camera, compass or microphone will work on iPhone, but not iPod touch.

Now it's ok to write programs that are limited to iPhone 3G or iPhone 3GS-but I think you'll be missing out on potential chunks of target audiences.

7. Always document your ideas

Before you add any code to a new project, take some time to record your final experience. This does not have to be long document requirements. It could be as simple as writing down a few notes on a paper or sketching a drawing.

It's really a great sketching product called UI Stencils that lets you spot the screen design on paper. I love it and highly recommend software development.

8. Provide High User Experience

When you start viewing Apple Docs, there is one repeated theme that you see in a document called Human Relations Guidance (HIG). Essentially, this is the main document about how the iPhone should look and behave. Be sure to familiarize yourself with it.

It is also important to download and test other programs made by other major developers. To ensure a lot of user experience in the application, ask yourself why these programs are leaders and what factors they used to create a lot of experience. See also the ideas of critic Jakob Nielsen.

9. Data Management

Oh, before I forget, one of the most complex things you need to consider is data management. If your application is a basic utility (e.g., calculator), you should not worry about storing data. If you build applications that are related to internet services, you connect these online resources with web services. Your third option must store user data on your device using the Core Data Framework.

10. Manage Memory and Battery Life

Those who are a bit technical understand what I mean by memory and battery life management. Note that there is no garbage disposal for iPhone. Collection collection is a programming period, which means that if your application has "less leakage", it may cause the iPhone to eventually crash without warning.

Also, note that certain iPhone features will use more battery life than others. For example, programs that stream data from the internet or make use of the basic frame (eg GPS) will drain the battery life faster.


I certainly hope this article has given you the headline of what you need before you write the Apple app.

There are several things you need – Mac OS X computer, Objective-C knowledge, UI design, experience, among other things. But if you're serious about going on your reconstruction, you should not be the mood.

Learn a little every day and make sure you'll become a rather expert developer in no time!

Next time, I will write some articles on how to program applications in Xcode device and Objective-C. Until then, enjoy learning to develop those programs!
