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.
