How to escape only unescaped quotation marks Objective C

I'm receiving a JSON response and I need to escape quotation marks. This is The string I get:

"sign":0,"text":"Continue onto William Elton \"Brownie\" Brown Freeway, I 580"

Now, I need to get the string looking like this:

\"sign\":0,\"text\":\"Continue onto William Elton \"Brownie\" Brown Freeway, I 580\"

But, when I call this method

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

What I get is:

\"sign\":0,\"text\":\"Continue onto William Elton **\\"Brownie\\"** Brown Freeway, I 580\"

So the problem is with the bold part, Brownie, that already had quotation marks, before I started replacing them. How can I solve this, and only escape " and not \" as well?

To do what you asked for, first un-escape the escaped quotes:

Use stringByReplacingOccurrencesOfString to change all the \" into "

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

Then use stringByReplacingOccurrencesOfString to change all the " into \"

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