Back slash issue while comparing two strings

Question

I am getting some string from service

  <iframe width="560" height="314" src="http://www.youtube.com/embed/oWeXKVioM34" frameborder="0" allowfullscreen></iframe>

I just replaced the string like this

  summary = [summary stringByReplacingOccurrencesOfString: @"\"" withString:@"\\\""];



    NSString *str2=@"<iframe width=\"560\" height=\"314\" src=\"http://www.youtube.com/embed/oWeXKVioM34\" frameborder=\"0\" allowfullscreen></iframe>"// this is my expected string which i got in console area for summary.

I am getting exactly in console area but if I compared the strings

      if([str2 isEqualToString:summary])
                {
                    NSLog(@"same......");
                }
                else{
                    NSLog(@"notsame ......");
                }

I wondered I am getting notsame as output even they appear same in console area. Then I calculated the length for summary it is 129 and for str2 it is 121. then I got that there is a problem of backslash because I added 8 slashes,then what to do to get same output.

any help would be really appreciated. thank you.

Backslash is used to represent special characters like " on a NSString literal. So, actually the str2 string doesn't have any backslash, while the summary string do (added by stringByReplacingOccurrencesOfString:withString:).
