Named UIP package between applications?

Can I use a named UIP archive (i.e. not a global one) to transfer data between two applications?

  • applications are completely independent of each other, therefore they have different package identifiers from different providers
  • I would like to use named cardboard, so custom content in the global cardboard is not overwritten.

Apple docs say:

Frames can be public or private. Public printed circuit boards are called system boards; Private file cabinets are created by applications and are therefore called application collections.

It is understood that cardboard may be "global and publicly available" or "named and private."

I created two applications with different package identifiers and it seemed that I could transfer material from one application to another using a private named cardboard. But is it just a feature of iOS Simulator or something that was really supported but not well documented?

Thank you for understanding!

You can set a custom string for the value of your cardboard and use it in your applications so that your applications can access the value using your unique string:

UIPasteboard *pasteboard = [UIPasteboard pasteboardWithName:@"youruniquestring" create:YES];

[pasteboard setPersistent:YES];

//save the unique identifier string that we created earlier
[pasteboard setString:@"your message"];

It is supported. Keep in mind that named cardboard will disappear if both applications that configured it are deleted, so do not use it to store everything that you do not have a backup.
