IOS: Can you record without displaying video?
The answer is absolutely.
You can hide the capture / video view as the other answer suggests, but if you already have permission to use video (and / or audio if it's an AV stream), you can do whatever you want.
Of course, I stick with "don't be mean" like your shtick, as one of the important but purposefully vague rules of app store presentation is simply "they know something is wrong when they see it."
See my answer here for a very close question and answer.
