writeToFile和encoding（objective-c）

Question

here is my code, i try to load a html file to an string variable then write it to a html file on computer again, but the problem is that when it export the file and i open the html file by browser it shows me the html content file unexpectedly!

  NSURL *url=[NSURL URLWithString:@"http://www.google.com"];
        NSString *web=[[NSString alloc]initWithContentsOfURL:url];

   [web writeToFile:@"/saleh/index.html" atomically:YES encoding:***NSUTF32BigEndianStringEncoding*** error:&theError];

as i think here is the problem encoding, isn't it?

Answer 1

Yes, it is problem of encoding, use NSUTF8StringEncoding

NSURL *theURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@", @"http://www.google.com"]];
NSString *web=[[NSString alloc]initWithContentsOfURL:theURL];
[web writeToFile:@"path/gp.html" atomically:YES encoding: NSUTF8StringEncoding error:&error];
