I realize this is a difficult question without a straightforward answer, but I'm hoping for some suggestions of frameworks or libraries I should start with.
Imagine a view that contains a background image, some smaller images overlaid, and a small video (an MPMoviePlayerController view) overlaid. What I need to do is create a composite video of the entire view. So the final result saved to disk would be all the images and the video combined into one video file.
What AV tools are available that would be most likely to help accomplish this?
AVAssetWriter seems to be the best option for doing this.

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.

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.
http://www.raywenderlich.com/18840/
I think it should give you a hint on how drawing works.

In my application, you can take photos or choose photos from the library in order to use them as a background image later.
I would like to ask for a tutorial that explains how to save these photos using Core Data.
Sorry if this question is not appropriate, I know that StackOverflow is only for code questions. And sorry for my bad English, I am Spanish.
Thank you!
Here this is a nice tutorial. It teaches you how to use core data over all but it also teaches with pictures. By the way you need to create a new attribute with the type binary data to save the photo. Basically you need to convert your image into NSData and then save it in your attribute. To get it out convert NSData to a UIImage.

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.
