check for garbage value Objective c

Question

I am trying to get the range of a particular substring using rangeOfString method of the NSString instance.. the problem is it sometimes returns garbage value..

Is there a way i could do a comparison for the garbage value and skip the next steps if the range sent is garbage..

thanks!

If the range is not found, you'll get a NSRange with {NSNotFound, 0} . You can find this here in the documentation.

This is the test you'll want:

NSRange range = [myString rangeOfString:@"doobleydoo"];
if (range.location == NSNotFound) return;
