Declaration
class CachedURLResponse : NSObject
Overview
A Cached
object provides the server’s response metadata in the form of a URLResponse
object, along with an NSData object containing the actual cached content data. Its storage policy determines whether the response should be cached on disk, in memory, or not at all.
Cached responses also contain a user info dictionary where you can store app-specific information about the cached item.
The URLCache
class stores and retrieves instances of Cached
.
