使用AVCapture捕捉高质量图像的简单方法

Question

All I need to do is capture an image, and all I can find is complicated code on capturing video or multiple frames. I can't use UIImagePickerController because I do not want to see the camera shutter animation and I have a custom overlay, and my app is landscape only. What is the simplest way to manually capture an image from the front or back live camera view in the correct orientation? I don't want to save it to the camera roll, I want to present it in a view controller for editing.

Take a look to the SquareCam ( http://developer.apple.com/library/ios/#samplecode/SquareCam/Introduction/Intro.html ) example from Apple. It contains all what you need for high-quality capture of images. I recently copy-pasted the code from this project myself where I solved the same task as you. It works well :)
