In this article, I'll discuss how to write iPhone apps from a developer perspective. Meaning, those
that have written applications or designed websites.
Developing iPhone applications include two main areas of learning: the Objective-C language
along with the iOS framework and provisioning mobile devices. Objective-C is the language used
to write against the iOS framework. The iOS framework includes constructs that allow you to
communicate with networks, process events within the application, and retrieve data from a
database to name a few of its features. There are also subsets of the framework such as Mapkit,
Notification Center, and Game Center.
The second area of learning is device provisioning. Provisioning is the process of making the
mobile device trusted and copying your application from the computer to the mobile device.
Creating trust usually consists of installing certificates on the computer and mobile device.
For those that have never developed on mobile devices, this can certainly be a time consuming
area to learn because it is such a tedious process. Device provisioning is tedious because of the
various and numerous number of errors one might receive. Lack of documentation on these issues
can make provisioning a lengthy endeavor.
The iPhone development environment consists of Xcode. Xcode is an IDE (integrated
development environment), designer, debugger, and includes instrumentation for testing
performance. Xcode can be integrated with code repository products such as SVN. Xcode is free.
However, to submit iPhone applications for sale, you must join the developer program, which costs
$99 per year.
Apple has provided a large number of tutorials and documentation at their developer site.
Additionally, the iPhone developer community is very active. There are a large number of forums
for seeking help. As you work through your first few applications and begin running into problems
that are taking some time to figure out, it is likely you will find others that have experienced the
same issue.
Experiencing problems when learning a new development language and framework is a good
thing. It is taking you off of the beaten path and allowing you to dig in. This kind of exploration will
help sear how particular areas of the language/framework work or should be used. These
experiences also add to your toolbox. Next time you come across a particular issue, it will not take
as long to solve. Eventually, you will begin developing faster and more efficiently in this very new
environment.
