In my project i'm creating a file using the function:

- (BOOL)createFileAtPath:(NSString *)path contents:(NSData *)data attributes:(NSDictionary *)attr;

I want to grant this file permissions so only the user can read and write (-rw------). I cant figure out (or find documentation) how i should fill this attribute dictionary (keys and values).

Thanks in advance

Who are you protecting the file from? –  trojanfoe Jul 24 '14 at 9:23

It's not clear what you expect to gain from this, but the syntax is:

NSDictionary *attributes = @{
    NSFilePosixPermissions : @((short)(0x600))
};
BOOL created = [[NSFileManager defaultManager] createFileAtPath:path
                                                       contents:data
                                                     attributes:attributes];

Not sure if you actually need the (short) cast or not.

It's not that important, but i still want to play it on the safe side. can you tell me where can you find documentation for it? Thanks! –  Zbun Jul 24 '14 at 9:29

Shouldn't the value be 0600, not 0x600? You want the octal value 600, not the hex value 600. There's a big difference. –  rmaddy Jan 30 at 16:20
