I am preparing presentation, and would like to put approximate figure of total number of classes available in iOS SDK. kindly easy go, if the question is not a question.
If no link available, kindly let know how to figure it out ?

To have a brief overview of iOS and MAC OS X classes, use RuntimeBrowser
And to check the APIs added with every release, API differences

On iOS 7.0.4 runtime reports 3138 classes on iPhone 4(6 of them do not conform to NSObject protocol) but you'd have to filter private classes somehow(and filtering classes which start with _ will remove only part of them). I'd say that around 500 of them are public, but that's a blind shot. And with each (at least major) iOS release classes count will increase.

I am suck by the issue that when I am writing code for my app's UI, I often need to adjust some frame parameter, but after that , I need to build and run Xcode again, I can not see the effect real-time.
After some google search, I find this project: RestartLessOften,but it seems to do a lot more to get it work! Anyone find an easy one that I can see my UI effect at real-time?
There is an alternative to RestartLessOften, that is Injection for Xcode Source. I dont know, if its better than RestartLessOften, but it might help other users as an alternative to RestartLessOften.
Reveal allows you to inspect and modify many aspects of your UI at runtime, beyond simply the frame. It costs money, but it works.

We recently added some policies to out fairly large Lua project, which also includes some stricter style guidelines than we used to.
The problem we are facing now is to convert the whole codebase to the new style guidelines, which is a lot of work. I started reformatting the code and got tired of it after about 5 files out of hundreds.
My idea is to use a code formatter, which automatically does this for me. However, the output format needs to be according to our style guidelines and not any different style. We also have some unusual guidelines, like a space before the opening parenthesis for the argument list in a function definition.
All this makes it fairly hard to find a suitable formatter. Does anyone know about one that meets all my criteria? Any help will be greatly appreciated.

I find it hard to locate some kind of information source which will give me a breakdown of the most used iOS versions as of today. I am working on my app and trying to decide on my "Deployment Target". I want to choose iOS 5.0 but not sure how many iOS 4.x users are out there. Does anyone know of a good place to get this information?
You can have a look here for iOS usage statistics.
As for me, it's ok just concerning about iOS 5, 6 and 7.
Forget about using third party sources for this kind of information.
You only care about marketshare for your specific app which will almost always we wildly different to the global average across all apps.
The only real option is to have some kind of tracking in your app, where it sends the OS version to the server once per week for similar for each user.
For a new app, you should support as many version back as you can with a reasonable amount of development effort. Then use actual statistics gathered from your app to decide when to drop old OS versions.
Accoring to this and this, iOS7 has over 50% usage.

I want to do something like this:
With iPhone's camera and AR tech, I could stick one virtual paper to the desk in front of me in the real world and wherever I put my iPhone around that place I stick the paper and it still seems that the paper is on the original position where I've put it at first.
If I want to make it come true, what do I need? And what SDK is more suitable for me to use?
This question is pretty old now. Is it still open? You can try out Qualcomm Vuforia
Take a look at http://socialcompare.com/en/comparison/augmented-reality-sdks to see which AR SDK support iOS. You can start by looking into ARToolkit, Metaio, String, Vuforia, and Wikitude.

How do I obtain the Natal SDK? Where to take it from (google had not given me lot of help)
There is now a third-party (open-source?) SDK available from Code Laboratories. The NUI SDK is still under development, but you can download it and start using it.
well, I've looked around, and I can't find it (legal or otherwise).
The natal kinect SDK would be great fun to play with... come on microsoft and xbox!
It appears that Microsoft have released the SDK to a limited number of games studios but it is not freely available. You might be able to find a pirate copy on a torrent site if that sort of thing doesn't bother you.
