Steps and procedures for developing and publishing an iPhone app to iTunes

The process for developing an iPhone app is not as complicated as you think, and of course it is not very simple. There was a news report that a 9-year-old child can develop an iPhone app. I believe you will be fine. Don't be scared at all. Developing an iPhone app is similar to cooking, and requires a process step by step. This article will not detail each step, but will only show you how to publish the developed iPhone app to iTunes.

First, we should point out that the biggest difference between iPhone app development and Android development is that android is free, and iPhone apps are charged. The fee is USD 99.00. You also need a Mac computer and some specified software to complete your development. Basically, let's develop it.

1. Draw your iPhone app blueprint in your mind

App Store already has many applications. If you want to succeed, you must have a unique idea and idea. Don't be impulsive. If you really make up your mind to make a gold rush, sit down and think about how you can make your app stand out? Why do users want to download your app? Finally, why are they willing to pay for your app?

So before you start, you should first go to the App Store to find out if you already have the app you want. If they already exist, you should think about where their shortcomings are and how can you do better on their basis. If you think you have a chance, you 'd better put your ideas on paper.

2. Prepare a Mac Machine

The iPhone is a product of apple, and you must have a Mac machine to develop the iPhone app, because all the iPhone development tools currently only run on the Mac operating system platform. (However, it seems that some jailbreaking tools can be run on a PC ). If the funds are insufficient, you can consider a second-hand Mac or Mac Mini.

3. Register as an apple developer

To use Mac development tools, you need to register as a formal Apple developer. Registration is free. You must agree to Apple's terms. You can use your iTunes account and password to register.

4. Download the development kit for iPhone (SDK)

When you register as a developer, you can download the SDK for the iPhone. The SDK version depends on the operating system version you are currently running. The installation package is large because it contains various types of documents, code cases, and these documents and code will be very useful during your development. It may take several hours to download it. You can make a detour.

5. Download xcode

The next step is to download xcode. Scode is a complete and full-featured ide tool. You have a friendly user interface. you need to use it to edit code, compile and debug applications. Similarly, this file is huge. You can take another lap.

6. Use the template in the SDK to develop your first iPhone app

Of course, you already know what app you want to develop. We recommend that you use the template in the SDK to develop your first iPhone app. You will realize that the waiting time for the two downloads is worthwhile. You can select similar projects from a large number of templates and find useful videos.

7. Learn cocoa objective-C

If you are a programmer, you will fall in love with objective-C. If you don't understand programming, it may take you some time to chew on this hard bone. Or you can hire someone with objective-C to help you complete code work. There are also many related books. You can search for them.

8. Use objective-C to write app code

When you can use objective-C to start code writing, you can start code writing. A simple application can be written in just a few hours, but it may take several months for a large application to write code.

9. Use iPhone simulator to test the iPhone app

The SDK comes with an iPhone simulator (simulator) that is equally powerful ). Before release, you must load your app into the simulator for some testing. Use as many scenarios as possible to simulate users using your applications, locate bugs in the applications, and improve your application code.

10. Upload the iPhone app to iTunes

Do you think you have never mentioned the $99 thing? No, it's now. If you want to upload an app to iTunes, you need to pay $99. This fee is required. I believe you have the confidence to make them back. After the payment is successful, you can invite other developers in the community to help you test your application. At the same time, you also have the opportunity to get an apple upgrade before the release.

11. Submit the iPhone app for review

It's okay to invite others to test your app in the developer community. You can submit the app to iTunes for review. The review takes a long time. You need to wait patiently.

12. Start selling iPhone apps

After the app you submitted is approved, you published a paid app. Now you just need to sit in a chair and dream that the dollar source will constantly flow into your account. Of course, if you publish a free application, you are more concerned with the number of downloads and installations. This is the process from creation to release of the iPhone app. Wish you a big sale of the iPhone app!
