Delete NSUserDefaults Content Using the Terminal

Preface

Most of you are very familiar with NSUserDefaults. Today I’ll show you how to clear NSUserDefaults information using the terminal

NSUserDefaults is like the registry in Windows development; it’s used to store some flag bits Recently in development, what I needed most was clearing NSUserDefaults information without running the code

$ defaults delete + bundle identifier eg: com.baidu.demo

The following deletes all files with com.baidu.demo as the bundle identifier

1

$ defaults delete com.baidu.demo

The actual path (replace my app and the arrows before and after with your own app’s bundle identifier)

For macOS apps without sandbox (see below): ~/Library/Preferences/<my app>.plist <my app> eg:QQ

For macOS apps with sandbox (see below): ~/Library/Containers/<my app>/Data/Library/Preferences/<my app>.plist eg:qq

Summary

defaults also has other commands, such as setting a value for a key. You can google it yourself

Thank you all
