iOS中的永久文件位置

Question

When deploying to an iOS, the documents path of the previous copy of the app is deleted and a new documents path is created and the files are copied to that new path.

What if you want to place a file that you do not want to get deleted each time you redeploy your app? Is this possible and if so where is a good location to place this file?

Thanks.

You are talking about when you compile and deploy from Delphi to the device. It uninstalls the previous deployment of the app first before it installs the new deployment. Naturally this deletes everything in the app sandbox.

Normally, in real life this would not be a problem because updating an app to a newer version from the app store leaves alone anything that is in the Documents directory.

This applies to XE5 and older. In XE6 this behavior has been changed. In XE6 the deployment to device leaves the old documents, data and cache directories alone, so the old stuff stays there. And there is an optional switch to do it the old way and delete everything.

So, the solution is to upgrade to XE6. There is no other known way.
