Question

I separated some processes. I have two application and i want to access database of one of them from another. Is there any way to access?

Answer 1

No you cannot access database in one app from another app.

However there are always workarounds, such as using UIPasteboard

The UIPasteboard class enables an application to share data within the
application or with another application using system-wide or
application-specific pasteboards.

1. First you will need to create an application-specific pasteboard by pasteboardWithName:create:
2. You can then save your database in one app, and convert it to NSData, then put it into your application-specific pasteboard with setData:forPasteboardType:
3. You can read the NSData with dataForPasteboardType: and convert it back to your database format

Hope this help.
