如何在iOS上的UIImagePicker中获取实际图像帧的大小？

Question

I am implementing a kind of "augmented reality" app which has to add guide to the user on the image being taken. In order to do this camerOverlayView is used. The problem is that I have to place the guide on the image too. For that I need the size and the position of actual image on the UIImagePickerController . Where can it be found from?

For iPhone 4: 5.0 MP (2592 x 1936) - Frame : (0.0, 0.0, 2592.0, 1936.0)

For iPhone 5: 8.0 MP (3264 x 2448) - Frame : (0.0, 0.0, 3264.0, 2448.0)
