iOS Sandbox (sandbox)

iOS sandbox

Each iOS app has its own app sandbox, the app sandbox is the file system directory, and by default iOS apps only have access to their own sandbox

Extenaion is a new open-iOS8 extension mechanism for several fixed system regions, which can compensate to some extent the limitations of iOS sandbox mechanism to inter-application communication.

Application Package:
