This gave me a problem with NSUInteger being unassigned long. Xcode (4.3)gave me a solution:
Change %i with %lu. So logging will be:
NSLog(@"Location is %lu and length is %lu", range.location, range.length);

thank you for making my transition from C# / C++ to Objective C an easy one. Can't wait to get to the iOS tutorials!

@jindak126 I've been fiddling around with them for a while, and generally there is no difference. I don't know why or when there is (I'm a noob), but x.y and [x y] usually yield the same result.

@iamafractal i might not know the exact reason but i think range cannot be an object because i dont think you can point to a range

ok why exactly is range NOT an object? bucky says, "this doesn't need to be an object…" or something like that… but WHY?
