Thread SafetyThe UserDefaults class is thread-safe.

Should I use UserDefaults?

When to Use User Defaults? The defaults system is ideal for storing small chunks of data, such as settings or the user's preferences. The user's defaults database is stored on disk as a property list or plist. A property list or plist is an XML file.

What is NSUserDefaults?

A property list, or NSUserDefaults can store any type of object that can be converted to an NSData object. It would require any custom class to implement that capability, but if it does, that can be stored as an NSData. These are the only types that can be stored directly.

Is NSUserDefaults encrypted?

NSUserDefaults are stored in plist in binary format, with no encryption, and is stored in your app's directory.

When I store data:

  1. User preference data: Settings,Accounts... - NSUserDefaults
  2. Security data：passwords - KeyChain
  3. Small amount of data that do not need complex query - Plist,Archiver
  4. Big amount of data which need Structured Query － Coredata/SQLite(FMDB).
