There are several points to note when Swift implements object archiving To inherit nscoding, implement two methods Extension is a classification, the classification does not allow storage capacity, so the protocol method can not be written in the classification The init (coder Decoder:nscoder) function in the protocol overrides the original constructor, so there is at least another Init method in the class If you do not specify a

This is a good the to create backups and archives.Some of tar' s options include: - C -create a new archive - f -when used with the- C option, use the filename specified for the creation of the tar file; When used with the- x option, unarchive the specified file - t -show the list of files in the tar

IOS Application Data storage mode (archive) One, simple explanation In the use of plist data storage and reading, only applicable to the system with some of the common types to use, and must first obtain the path relative trouble;Preferences (keep everything under the same folder, and primarily to store settings for the application)Archiving: Because the first two have a fatal flaw, you can only store commonly used types.
