From one of the users of my screensaver, I get the issue report that resolving
the SSB does not work.
He is running macOS 10.14.6 on a Mac Mini.
I have compiled my screensaver using the current version of Xcode, under macOS
14, but for the target macOS 10.13.
When my screensaver tries to resolve the bookmark, I get the infamous
Code%9 "The File couldn't be opened because it isn't in the correct format."
This happens, when my screensaver is launched by the ScreenSaverEngine.
When my screensaver is running in System Preferences, in the thumbnail window,
everything is fine, and resolving the bookmark works, of course.
Also, there are other users of my screensaver (including me), where it runs
just fine.
For that user, the directory for which my screensaver creates the bookmark is
on an external HD.
Below is the source code showing how I create/resolve bookmarks.
Any ideas what I could try (or the user) will be highly appreciated.
Best regards, Gabriel
Create bookmark:
NSData * dir_bookmark = [dir bookmarkDataWithOptions:
NSURLBookmarkCreationWithSecurityScope
includingResourceValuesForKeys: nil
relativeToURL: nil
error: &systemError];
[no problems occur here]
Resolve bookmark:
NSURL * dir_location = [NSURL URLByResolvingBookmarkData: bookmark
options:
NSURLBookmarkResolutionWithSecurityScope
relativeToURL: nil
bookmarkDataIsStale: & isStale
error: & error];
[at this point, dir_location == nil, and I get the error code 259.
I can still extract the path using this code:
NSDictionary * dict = [NSURL resourceValuesForKeys: [NSArray
arrayWithObjects: NSURLPathKey, nil]
fromBookmarkData: bookmark ];
.. = [NSString stringWithFormat: @"Orig path: %@", [dict
objectForKey: NSURLPathKey];
