Where is UIPasteboard physically located?

Question

Where are the contents of an app-specific UIPasteboard physically stored on a device?

Is this something which is backed-up when iTunes backs up the device?

So, in terms of security, would one want to encrypt data sent to the UIPasteboard?

Answer 1

From UIPasteboard Class Reference:

A pasteboard is a named region of memory where data can be shared. There are two system pasteboards: the General pasteboard (UIPasteboardNameGeneral) and the Find pasteboard (UIPasteboardNameFind. You can use the General pasteboard for copy-paste operations involving any kind of data; the Find pasteboard, which is used in search operations, holds the most recent string value in the search bar.

Info about app-specific pasteboards:

Apps can also create pasteboards for their own use or for use by other apps that have the same team ID. A pasteboard must be identified by a unique name. You may also mark an app-specific pasteboard as persistent, so that it continues to exist past the termination of the app and past system reboots.

However, the documentation does not specify where the items are stored.
