Answer 1

While the core of the answer comes from Brad at iOS: Get pixel-by-pixel data from camera, a key element is completely unclear from Brad's reply. It's hidden in "once you have your capture session configured...".

You need to set the correct outputSettings for your AVCaptureStillImageOutput.

For example, setting kCVPixelBufferPixelFormatTypeKey to kCVPixelFormatType_420YpCbCr8BiPlanarFullRange will give you a YCbCr imageDataSampleBuffer in captureStillImageAsynchronouslyFromConnection:completionHandler:, which you can then manipulate to your heart's content.
