I have a string which I want to insert to an ObjC `NSURL.UrlWithString` function, but it has to be without any quotes.

bad example:

```
$.NSURL.URLWithString("http://192.168.1.1")

```

In JavaScript, I know I can do something like `StringFromCharCode(34,90,81,33)` to avoid quotes, but what is the alternative in Objective C? (not Swift).
