Apple has launched the new Xcode 4 for the iOS Application Developers. It is for sure that the developers are going to love it because of its awesome features. Lets have a look at some of its new features.
What’s new in Xcode 4
The tools in Xcode 4 are redesigned to work faster and smoother. It has become more helpful, and it not only tells you error but also fix it for you.
Some of the new features which you will notice at first….
Yes, the Xcode 4 is a single window development environment which combines Interface builder in the same window in which you write code.
Interface Builder is Built-in
There is no seperate application called interface builder. Infact, interface builder is integrated with Xcode. Selecting a .xib file will directly open editor in Xcode. You can drag connections directly from UI design to source code. If your code is not ready with actions and outlets then just drag connection to empty space in source code and Xcode 4 will define outlets and actions for you.
This is another useful addition in Xcode4. If you make some changes in a source file then assistant will help you in determining which other source files need to be checked, as you work.
The Xcode 4 is an IDE which is intelligent enough, not only to report but also fix problem for you.
How to create iPhone/iPad applications and submit them to App Store
So today we are going to see how to create iPhone/iPad applications and then submit them to App Store. So basically we will be starting with the requirements first that we need to get us started.
Requirements for building iPhone application
You can build an iPhone application only on a Macintosh computer. Macintosh computers run Mac as their operating system, and are completely different from Windows. You cannot install Mac operating system on a Windows PC as it is hardware dependent. So guys if you own a Windows computer then get ready to shed some money for buying your new Mac. You will feel the difference between them from the day you start using Mac.
Xcode is an integrated development environment developed by Apple. Applications for iPhone/iPad are developed using Xcode in Objective c language. You can download Xcode by registering on Apple’s developer website. Xcode is downloaded as a complete package which consists of a programming environment for writing codes, an Interface Builder for designing pages and an iPhone simulator for testing applications.
iOS Developer Program
Ok, this is not so good part as it involves some more expenditure after you buy your Macbook. Apple needs you to be enrolled in its developer program before you can start putting applications on app store for sale. There are two membership programs, depending on whether you are a company(iOS Developer program Enterprise – $299) or an individual(iOS Developer Program Standard – $99) you can select your membership. After you get registered you can submit your application for sale on app store.
