如何在 iOS 扩展应用程序上使用 IPC（基于 C++）？

Question

I am currently implementing an iOS App using QT. Although it is a QT-generated Project, it is very similar to iOS.

I added the Extension App to Main App and I would like to use IPC without pure iOS function. So, I want to use shared momory or named pipeline (C++ based).

But I lack knowledge of ios. So I don't know sandboxed path of Extension App. Which path should I create a pipe line at (using mkfifo function)??

I attached the information about my extension app as a screenshot.

• I tried to create a pipe line in relative path, but it failed.

Answer 1

The /tmp path only worked on the simulator. In order to operate on the device, after adding the App Group, it took the App Group path and created a pipe line in that path, and it worked correctly
