Hi everyone,
I’m having some troubles getting the last used date of a file, can anyone see
issues here with my code?
NSDictionary *fileAttributes = [[NSFileManager defaultManager]
attributesOfItemAtPath:anObject error:NULL];
if (fileAttributes != nil)
{
MDItemRef item = MDItemCreate(NULL, (CFStringRef)anObject);
NSDate *aDate = (NSDate*)CFBridgingRelease(MDItemCopyAttribute(item,
kMDItemLastUsedDate));
if (!aDate)
{
NSDate *fileCreateDate = [fileAttributes
objectForKey:NSFileModificationDate];
}
}
My problem is I’m only getting a kMDItemLastUsedDate on about 10% of files I
check, and even though I always get a value for NSFileModificationDate it still
doesn’t seem to always be the true last used date. For example looking at how
Path Finder does it they have an Attribute tag that seems to more correctly
give the last date file was used. Any input here would be appreciated thanks
in advance...
