Never mind, I just got rid of it and cast the struct directly:
- (void) setBundleBitOfFile:(NSString*)path toBool:(BOOL)newValue
{
const char* pathFSR = [path fileSystemRepresentation];
FSRef ref;
OSStatus err = FSPathMakeRef((const UInt8*)pathFSR, &ref,
/*isDirectory*/ NULL);
if (err == noErr)
{
struct FSCatalogInfo catInfo;
err = FSGetCatalogInfo(&ref,
kFSCatInfoFinderInfo,
&catInfo,
/*outName*/ NULL,
/*FSSpec*/ NULL,
/*parentRef*/ NULL);
if (err == noErr)
{
if (newValue)
((FolderInfo*)&catInfo.finderInfo)->finderFlags |= kHasBundle;
else
((FolderInfo*)&catInfo.finderInfo)->finderFlags &= ~kHasBundle;
FSSetCatalogInfo(&ref,
kFSCatInfoFinderInfo,
&catInfo);
}
}
}
Thanks - it does the job for me.
One small follow-up question though. I'm also trying to set the extension of
this package file hidden by default, using:
[[NSFileManager defaultManager] setAttributes:[[self class]
defaultFileAttributes] ofItemAtPath:[self path] error:&error];
Where the default attributes are:
+ (NSDictionary*) defaultFileAttributes
{
return [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber
numberWithBool:YES], NSFileExtensionHidden, nil];
}
But the extension is not hidden. Opening Get Info in the Finder, the "hide
extension" checkbox is greyed out, though is is checked, as if the extension
were hidden.
Any idea what's going on there?
