How to create a folder/file on iPhone device Library?

Question

I like to access the device Library folder (not app's document directory). Actually i am trying to create one file in Device Library folder and want to access this file from another app. Any idea ?

Answer 1

You can't, apps in the iOS are sandboxed and can only write in there own environment. Also there is no library directory.

Answer 2

终于，现在可以通过应用程序扩展了，但是3年后:)

Answer 3

如果您确实希望在应用程序之间进行数据传输，则可以使用钥匙串。
