The Image Capture API allows developers to leverage the Camera Connection Kit to import photos directly into their apps.
I haven't been able to find in the docs or WWDC sessions where it talks about this. I have an app for our action camera and would love to be able to directly read the camera's filesystem over USB. I see where you can use a a document picker to access a USB filesystem, but that requires the user to properly find/select the correct directory in the camera's file system. I am hoping to be able to detect it and access it without the error prone user selection.
