NSKeyedArchiver/NSKeyedUnArchiver wrapper

Usage

Archiving

[LKDocumentDirectoryArchiver archiveRootObject:userList
                                        forKey:@"UserList"];

It executes like below functions.

// filename is equal to (Application Directory)/Documents/UserList.archive
[NSKeyedArchiver archiveRootObject:userList toFile:filename];

Unarchiving

id userList = [LKDocumentDirectoryArchiver unarchiverObjectForKey:@"UserList"];

It executes like below functions.

id userList = [NSKeyedUnarchiver unarchiverObjectWithFile:filename];

If required default value case,

[LKDocumentDirectoryArchiver unarchiveObject:userList
                                      forKey:@"UserList"
                                defaultObject:^id{
                                   return @[].mutableCopy;
                                }];

Supports handling failure,

[LKDocumentDirectoryArchiver unarchiveObject:userList
                                      forKey:@"UserList"
                                     failure:^{
                                        // do something
                                     }];

Using directroy

You can use directory.

[LKDocumentDirectoryArchiver archiveRootObject:userList1
                                        forKey:@"Support/01/UserList"];
// placed as bellow:
// (Application Directory)/Documents/Support/01/UserList.archive

The first "/" character will be removed. (e.g.) "/Sales/obj" => "Sales/obj"

Etc

You can remove an archive file.

[LKDOcumentDirectoryArchiver removeArchiverForKey:@"UserList"];

Check to exist an archiver file.

[LKDocumentDirectoryArchiver archiverExistsForKey:@"UserList"];

NSCachesDirectory is available too:

[LKCachesDirecotryArchiver archiveRootObject:userList toFile:filename];
