I joined Pramati a month back and on the very first day I was told to inspect
iPhone developement. Sine then I have been working day and night learning
and applying everything I come across. Just few days to go when I will give
a complete demonstration of my first application on iPhone. Its a mobile
version of Sugar CRM (for those who are unaware of what a CRM is, you can
find more about it at http://www.sugarcrm.com. And btw CRM stands for
Customer Relationship Mangement). So in this article I am going to share
all my experience, difficulties, things that I liked/ not liked with the
First thing that you should know before you start writing applications on iPhone
is Objective-C. As such its' not a difficult language to learn but there are some
specific features that make it more powerfull and some are just enough to make
life as difficult as you can ever imagine.You can find Objective-C tutorials on
http://www.developer.apple.com/iphone.As far as my experience says,
understanding these tutorials is really a heck of a job if you are not familiar with
Object-Oriented Programming. They donot teach you obj-c as other books do
it step by step starting from the very core of basics.So it might be frustating when
you are reading it for the first time (and if you have never developed anything on Mac),
but once you have given it a quick look, try some hand on example codes given on
the developer site and then read it again. It helped me and only after that I realised
the real power obj-c gives you.
In my examples that I will be posting sooner, you will find how even the minor controls
when taken from the compiler to the run-time can make you code so much powerfull.
But as obvius with great power comes great responsibilities. The compiler in such
cases is lame at reporting some of the absolutely basic mistakes we make at times.
An exapmple of such a situation is when you forget to mention data-type of a
parameter expected by a method. obj-c compiler will not even give you a clue of
what wrong is happening.But good news is if you write your code carefully and in a
structured way, it's a beutifull language to work with.
For all my brothers who are also new to this environment, here are some tips for
getting started with iPhone developement
- Learn the basics of Object Oriented programming(java if you know is very
- Give a quick look at obj-c (tutorials can be found here)
- Try playing around with the example code given on developer site of Apple,
- Try reading the concepts from the tutorial once again. It gave me a clearer insight of what exactly they mean to do.
And btw, You need Leopard and XCode to play around with iPhone developement, so get them sooner and have a happy coding and coffee nights :P
if you are facing any problems on iPhone developement, feel free to leave a comment and I 'll be more then happy to fugure it out for you :)
