I would like to develop a very simple application that allows a user to add shapes to a 3D model and view/rotate the model.
Where do i begin? What are the recommended frameworks for iOS?
Are there any good tutorials you can recommend me?

Apple's document OpenGL ES Programming Guide for iOS was very useful in my case. Describes the system integration using straightforward code. Also, gives you an overview about "background and multitasking awareness".
Also, there is a great tutorial for understanding the basic stuff by Ray Wenderlich

Is there any website similar to http://iossupportmatrix.com/ where I can find the matrix of ios frameworks and compatibility. Basically if I want to use some of the framework feature I would like to refer to the matrix and see if the compatibility across os versions.

After quite a bit of searching Google, I'm surprised that I can't find something to walk me through this process. The Apple docs have a 'Design Guide', but no sample app or tutorial.
At the moment I'm a bit in the dark. What I'd like are the steps I'll need to take to do this from scratch - OR a link to a tutorial if one exists.
I too had this problem. After searching for months for a tutorial or sample code- <sarcasm>thanks for the help Apple!</sarcasm> - I found this answer. The developer created a GitHub class that makes this much much easier.
This guy hit the nail straight on with this implementation.

I am interested in learning MVVM. Sadly I cannot find examples and/or tutorials on the internet that use Delphi with database applications.
Can you post links or point me in the direction that I should go?
Thank you in advance.
Take a look at this CodeRage session.
This session will look at Model-View-ViewModel, one technique that leverages LiveBindings to not only minimize the effort required to slide different UIs in front of your code, but also increases the maintainability and testability of your app as a bonus.

I'm working on a project in which I want to add a draw/sketch feature that draws by the user's touches on screen. That way they can make simple drawings on a view. This is a concept used in many picture apps (i.e. SnapChat). I've done many Google searches but haven't found anything out there that I could use. Does Apple have a guide or class for this or is there are any algorithms or code out there that's available to the public? Please provide me with references or information regarding this topic. Thanks in advance for your time.
I really like the ray wenderlich tutorials.
They also have a tutorial on how to make a simple drawing app.

I think it should give you a hint on how drawing works.

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.
