    NSDictionary *attributes = [[NSFileManagerdefaultManager] attributesOfItemAtPath:patherror:nil];

   if (attributes != nil) {

       NSNumber *fileSize = [attributes objectForKey:NSFileSize];

       NSString *accountName = [attributes objectForKey:NSFileOwnerAccountName];

       NSString *createDate = [attributes objectForKey:NSFileCreationDate];

       NSDate *modifyDate = [attributes objectForKey:NSFileModificationDate];

       //文件大小

       if (fileSize) {

           NSLog(@"File size: %qi\n", [fileSizeunsignedLongLongValue]);

        }

       //文件创建日期

       if (createDate) {

           NSLog(@"File creationDate: %@\n", createDate);

            //textField.text=NSFileCreationDate;

        }

       //文件所有者
