I want to get some metadata for a remote file.
I tried:
NSString *path = @"/Public/UNIDATA/Blocks.txt";
NSURL *icuBlocksUrl = [ [ NSURL alloc ] initWithScheme: @"http" host: @"unicode.org" path: path ];
NSArray *keys = @[ NSURLContentModificationDateKey, NSURLCreationDateKey, NSURLFileSizeKey ];
NSError *outError;
NSDictionary *icuDict = [ icuBlocksUrl resourceValuesForKeys: keys error: &outError ];
Now icuDict is non-nil but empty.
What am I doing wrong?
Gerriet.
P.S.
Just seen in small print: “This method applies only to URLs that represent file system resources.”
So this is not expected to work. What else can I do?
