Declaration
@interface NSURLCredential : NSObject
Overview
The URL Loading System supports password-based user credentials, certificate-based user credentials, and certificate-based server credentials.
When you create a credential, you can specify it for a single request, persist it temporarily (until your app quits), or persist it permanently. Permanent persistence can be local persistence in the keychain, or synchronized persistence across the user's devices, based on their Apple ID.
