I need to determine whether a string (sourceString) contains another string (queryString) and if it does, at what offset.

I'm guessing that NSScanner might do the trick but I don't fully understand the documentation.

Let's say sourceString = @"What's the weather in London today?"

If I set queryString to equal @"What's the weather", I'd like a method that would determine that, in this case, YES (sourceString does contain queryString) and the offset is 0 (i.e. at the start of sourceString).

Any suggestions?
