ios emulator partition issue-CodePudding

I tried to find the file inside the ios emulator.
When I scan the directory all the time, it finds my Mac Book local directory.
I don't know why the external folder is being read by the emulator. Turn it off or Is there any way to access the folder inside the emulator?

The code proceeds from a test application written in Objective-C. Here's the code:

   if ((dir = opendir("/Users/macAccount")) != nullptr) {
    while ((diread = readdir(dir)) != nullptr) {
      printf ("target : %s", diread->d_name);
    }
    closedir (dir);
  }

==> result (This is the files of my account on the macbook.)

Is this normal?

CodePudding user response：

If you run your code within an iOS app, you should start from NSHomeDirectory() which points to the root of the app's data container (e.g. /Users/qwerty/Library/Developer/CoreSimulator/Devices/B14BE9CD-4977-4960-8833-6591B1DB5530/data/Containers/Data/Application/8F26289C-DA47-4A1A-A9FB-65BEA7623496 ). And traverse it using NSFileManager.

If you do it from a macOS app that is not sandboxed (e.g. a command line tool), you could start traversing simulator devices at [NSHomeDirectory() appendingPathComponent:@"Library/Developer/CoreSimulator/Devices"], and then for each device directory, traverse the apps inside data/Containers/Data/Application.
