iOS is a mobile operating system developed by Apple. It was originally named the iPhone OS, but was renamed to the iOS in June, 2009. The iOS currently runs on the iPhone, iPod touch, and iPad. While Apple’s iOS provides a more basic user interface than Mac OS X, each new version adds more features. For example, iOS 2 provided access to the App Store, which allowed users to download and install third-party apps on their iPhones. iOS 3 added copy and paste functionality and iPad support. iOS 4 was the first version to support multitasking and added the GameCenter feature. iOS 5 introduced the Siri voice assistant, and provided new cloud connectivity features.
Now we are going to discuss some important steps to keep in mind to develop iOS application:
- Have a unique idea for an app? There are many apps out there. Be sure to check that there aren’t other apps that do the same thing that you are proposing. Or if you want to create something better than an app that already exists, think about how your idea will be better. Draw it out on paper or on the computer.
- The iPhone is an Apple product and uses a variation of the Mac OS. Currently, the iPhone development tools are only available for Mac users, but in order to get it up in the App Store, you will eventually need a Mac to get it there.
- Without becoming an official apple developer, you cant work with the Mac tools. because registration is free so it is very easy to become a official developer. Once you register you can use the same user name and password for your iTunes accounts and can develop iPhone apps for any Mac products.
- After becoming an official developer, you can develop the SDK(software Development Kit) for iPhone. The version you need depends on the OS you are currently running. This download is HUGE because it comes with all sorts of documentation, sample codes, and all sorts of things you will be glad to have later on. It could take a few hours
- According to Apple, “Xcode is a complete, full-featured IDE built around a smooth workflow that integrates the editing of source code, with the build and compile steps, through to a graphical debugging experience – all without leaving the view of your source code.” This is another huge download.
- Once you have your app drawn out on paper or in Photoshop, you can start designing it with the templates provided in the SDK. This is where that HUGE amount of download time will be a huge benefit. You will have lots of templates to choose from, and there are a lot of great YouTube clip tutorials on how to use the templates effectively.
- If you love programming languages, you will love Objective-C. If you don’t know how to program, this is the part that can get pretty sticky, so you might want to find a programmer friend or hire someone. It really does help to get a book, too, for reference.
- Once you at least understand the basics of Objective-C, you are ready to program your app. It helps to take screenshots as you go along so you can remember what you tried. Some apps can take just a few hours to program while other Apps can take months.
- The SDK comes with a lovely iPhone Simulator. You will need to load up your app and do your own testing. You should try to work out as many bugs as possible and think about all the ways someone might use your app.
- Sadly, loading an app into iTunes costs a one time member fee of $99 (USD). There is no way out of this fee, but you might earn it back if your app is worthy. Once you pay your fee, you will be able to have others in the app community test your app and help you work out final bugs.
- After testing your app in the community and working out all the bumps, you can submit the app to iTunes for approval. You will be able to upload it right from the community. The process of approval can take some time. After getting approval If you created a paid app, just wait for the money to roll in to shore. If you created a free app, watch the traffic.
