Convert string to UTF8

Question

How to convert NSString to UTF8Encode ?

My NSLog print the same result as input string

    NSString*  username =@"MYUSERNAME";
    username=[username stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    NSString*  Password =@"MYUSERNAMEPASS";
    Password=[Password stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSLog(@"username=%@",username);
    NSLog(@"Password=%@",Password);

add special character '%20' or some more like this and check again. — Ajay Gabani, Jul 25 '16 at 06:28
Do you want to add % in the string or else do you want to remove % from string? — user3182143, Jul 25 '16 at 07:29

You need to use stringByAddingPercentEscapesUsingEncoding instead of stringByReplacingPercentEscapesUsingEncoding.

NSString *encodeUserName = [username stringByAddingPercentEscapesUsingEncoding:NSUTF32StringEncoding];

Also stringByAddingPercentEscapesUsingEncoding is deprecated so batter to use stringByAddingPercentEncodingWithAllowedCharacters like this

NSString *encodeUserName = [username stringByAddingPercentEncodingWithAllowedCharacters: [NSCharacterSet URLQueryAllowedCharacterSet]];
