I use the following methods to get the visibility of files in the

You're using LaunchServices which is the right way to do this, however
you are not creating the FSRef properly. John is right, you shouldn't
use NSASCIIStringEncoding as paths are definitely not ASCII. I use
CFURLGetFSRef to create the FSRef which is much simpler.
You also don't need to check for the period at the beginning of the
file name etc because the Launch Services check does all that for you.
I use code similar to this:
-(BOOL)isVisible:(NSString *)path
{
//check to see if the file is visible by inspecting the
LaunchServices attributes
FSRef ref;
if (CFURLGetFSRef((CFURLRef)[NSURL fileURLWithPath:path],&ref))
{
CFTypeRef isInvisible;
if(LSCopyItemAttribute(&ref, kLSRolesAll, kLSItemIsInvisible, &
isInvisible)==noErr)
{
if(isInvisible!=kCFBooleanTrue)
{
[visibleFolderContents addObject:currentFileName];
}
CFRelease(isInvisible);
}
}
}
