I have decided to enter the iPhone App development arena and as such have a couple of questions:
Coming from a business management background and having no experience/knowledge whatsoever in developing, what would be the right way to start?
I am aware that I should learn Objective C, to begin with; as well as OOP etc... will reading books and fiddling with iPhone SDK put me on the right track?
What else do I need?
P.S: I am very aware that this will/might be daunting to begin with but I am prepared and motivated.
If you have no development experience I would suggest starting on something other than the iPhone. Even a few days learning the ropes would make starting on the iPhone much easier.
Something like Python would allow you to play around and learn about programming and OO in a more forgiving environment than Objective C. Even some experienced programmers have some difficulties with memory management and the various foibles of the Cocoa touch frameworks. Obviously you'll need to learn all that at some point but trying to learn the basic principles of programming at the same time as fighting segmentation faults is a tall order.
Here is what i did ( although i am from a programming background ).oder important
Intel based mac
Join dev program ( this could be
the last step , but i wanted to something to keep my motivation high :) )
Read first 6 chapters of Programming
in Objective-C 2.0
started watching
stanford iphone course ( available
on itunes )
Started reading the grape-fruit
book ( while referring to 3 for
obj c questions )
Review tutorials/projects from appsmuck
Figure out how to use apple
documentation as reference
Subscribe to iphone blogs / podcasts
like mobile orchard / iphone devs
twitter accounts ( there are several
good ones )
Add iphone cocoa xcode objective c
tags to stackoverflow account
Update I was just reading this from prag programmers ..seems like high level overview that answers your question.
You will be best served if you have a Mac. Here is another post for you to look at. It pretty much talks to your concerns.
I'd recommend following tutorials to get familiar with things.

I'm a former professional software developer. I've been out of programming (doing ecommerce and marketing) for nearly 20 years, and I'd like to try getting back into software development.
I'm looking for advice on how to create a very basic and simple but useful application that I can own and promote. I'm hoping that this app will serve as a proof of concept for building more advanced apps. I'd like to be able to publish the app on my website and also make it available for iPhone and Android users through the respective app stores.
Does anyone have advice on how to do this?
Specifically, I'm trying to answer these questions:
What is the best, easiest language and framework to use for building a simple web or mobile application?
Any suggestions on what kind of utility the app should provide: e.g. calculator, weather update, unit converter, crypto, etc.?
Thanks in advance.
In 2000, I was the lead developer (pretty much the only developer for the first six months) for a company called Communitect. We were one of the first companies to create apps that used text messaging for bank transactions. We wrote most of the code in Java with a MySQL database, and our code ran on Apache Tomcat.
The company struggled because we were a bit ahead of the curve and ended up chasing a lot of squirrels.
I'm not looking to do something so innovative this time. I'd like to just make my own version of a digital mousetrap and see how the process works for building up its popularity.

I have good knowledge of C++ and after reading The Elements of Computing Systems I have a basic knowledge of how computers work. I made a list of topics I want to learn next and books I want to buy on those topics. One of them is operating systems, but the one on the top of the list is Game development.
I am still a noob on those topics, so I wonder if I should know how an operating system (unix specifically) works before trying to learn game programming (Opengl, etc). On operating systems I have the book Operating Systems by Tanenbaum, and I want to buy The Linux Programming Interface by Michael Kerish.
On game development I was planning on buying Game Engine Architecture and Game Coding Complete to acquire a general concept of game programming and how engines work and then learn Opengl.
I am really lost on what to do first and I hope this is an appropriate question. What should I learn first, what books should I read and in what order. Should I learn how a VGA works before trying Opengl? Are there any other topics I should know before delving into games programming. I am asking this because I like to know what I am coding, what the functions I am calling do under the hood, I don't like holes in my knowledge.
Thanks.
Fluffy opinion answer incoming. Take with grain of salt.
The nice thing about programming is that that you don't need to learn everything about everything to do one thing effectively. Knowing exactly how to implement a video driver isn't required for using OpenGL effectively. The point of OpenGL is to abstract that out so you don't have to worry.
Since you want to do game development, make a project. Like recreating Asteroids using OpenGL for graphics and writing all the game logic yourself. And set about completing it. In the process you'll learn much more than simply reading. Use books as reference. At least thats what I've found works for me.
The Operating Systems book is pretty good. Its the one I read in college. But those concepts presented in it, though interesting, are not something you'll have trouble learning simultaneously with game development or anything else.
Also you should read this: http://www.linuxforu.com/tag/linux-device-drivers-series/. It's a great article series that teaches linux driver development and operating systems concepts in the process.

I am new to iOS. A bit knowledge of obj. C.
So now from where I have to start?
I just want to go with basics of objects and Class. And how do we use property of iOS.
And after that where should I move.
Please post details of iOS 6, not older version.
This website is easy to start to program for iOS. I just started it two weeks ago with this website.
Also they have a cheat sheet to understand basic structure of obj-c.
They update their contents to new iOS versions frequently.
Hope it helps you.

Have a look at Stanfords course cs193p. It is available for free on iTunes:
https://itunes.apple.com/us/course/coding-together-developing/id593208016
and has a community forum dealing with questions about the course:
https://piazza.com/open-classes/coding-together
The course consists of lectures including live demos, and also provides assignments (for self study).
The official site is always the place to start :) ...
https://developer.apple.com/programs/ios/
(But you will soon find that learning Objective C is a pre-requisite ... so if you don't know it yet, try http://cocoadevcentral.com/d/learn_objectivec/)
First I recommend you to take a look at Lynda's "iOS SDK Essential Training (2012)" while you are having a couple of coffees, it is a very smooth introduction to iOS.
Then go ahead for Ray Wenderlich Blog for some well covered tutorials.
[iOS developer:tips]; is a nice place to follow for quick tips.
And finally come back here for your questions, eventually.

Wake on LAN so cool, just want to write a iPhone app to WOL my PC, but have no idea to code, any one can point me the way?
If you've no experience of programming, then this is a very large first step. (More of a sheer vertical incline really.)
As such, you might want to take a step back and have a look a some basic (or indeed BASIC) programming tutorials. (Google is your friend.)
Alternatively, Apple has good online documentation regarding Objective C and the Cocoa (the language and framework that iPhone applications are written in.) A good place to start for this would be Apple's Introduction to The Objective-C Programming Language.
Basically you need to send a magic packed as described here, to do that you'll need basic programming knowledge and some knowledge on socket programming, here is a good book on the subject. There are numerous examples of that.
But in the end perhaps I could persuade you to purchase one of several iPhone applications that do exactly that, or grab the free one?
You'll need an understanding of bsd sockets as well as the user interface kit framework to put the necessary controls on the screen.
Or of course download an existing free app like this one which does it already, automatically detects your mac address, and also tells you whether your machines are on or off:
http://itunes.apple.com/us/app/wake/id396566137?mt=8
All the best for your projects.

I come from a .Net C# background, what's the best way to learn how to program native applications for the iPhone?
Have a look at the Stanford course on iPhone development. It will really get you started.
Everyone has posted nice resources, but even if you already know the language you have to use, I just wanted to state it so that other people who probably don't know it, can see.
The language used for developing Apple sanctioned, native applications is Objective-C. Of course, you can mix in C and C++, but the SDK itself is in Objective-C, so you might want to learn that. It looks a bit scary at first to most people, usually those coming from higher level languages such as C#. The brackets and supposed 'verboseness' turns some people off. After a while though, it grows on you and you'll notice it's a very readable and self-documenting language.
I personally used the book titled Learning Objective-C which was perfect for me as someone who is already familiar with programming languages, preferably C-style languages, and wanted to learn about the main differences in that language. The other, longer and I imagine better reference of a book is the popular Programming in Objective-C 2.0. This book is longer and starts off assuming the reader has 0 programming experience, going over control structures, Object Oriented Programming basics, etc. I believe both books have cheaper and searchable PDF versions.
Have fun and I hope all goes well for you in this venture.
In case you didn't know it: You can also use C# to program on the iPhone through MonoTouch. And in fact MonoTouch does also compile down to native ;)
I found the Beginning iPhone 3 Development book to be a very good way to get started.
