strpos-type method

I've looked around for a while, and found some posts on CocoaDev, but 
nothing seems simple.

I'm looking for basic string searching functionality, like PHP's 
strpos() [http://uk.php.net/strpos].

Or rather, I want to know if a string is contained inside another 
string. if strpos() returns > -1 (or !== FALSE in PHP)
then the string is at the returned position.

But all I could find was NSString Categories that did a very long 
winded method, and had a comment with the following code
(Adapted for my app, natch)

   if (([[incomingText componentsSeparatedByString:@"(Quit)"] count] - 
1) > 0) {
       // It's in the string
   };

All I want to know is if the text "(Quit)" is in the incomingText 
NSString instance. Surely this can't be the right way?

Thanks for any help.
