Overview
QuickLookThumbnailing is a non-UI framework, so your app doesn’t have to link to either UIKit or AppKit. It generates a thumbnail as a Core Graphics image object and makes the thumbnail available as the CGImage property. In case an app links to AppKit or UIKit, the thumbnail is available through the NSImage or UIImage properties.
See QLThumbnail for more information about the different types of thumbnails that QLThumbnail can create.
