prepend NSString?

Question

I am getting a JSON response from a web service but it is not wrapped by the [] tags required by the JSON parser I am using so I need to Append and Prepend those characters to my NSString before I pass that to the JSON parser.

Here is what I haver so far:

NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
responseString = [responseString stringByAppendingFormat:@"]"];

The appending works perfectly now I just need to prepend the [ to this, can't seem to find this method.

Answer 1

Try this:

responseString = [NSString stringWithFormat:@"[%@]", responseString]

There are other ways of acheiving the same thing, I'm sure others will be provide more efficient methods, but if responseString isn't very large then the above should suffice.
