How To Check if a NSString Contains Another NSString

So, you want to see if a string includes a given sub-string in iOS, huh?

NSRanges and NSString searches in iOS aren't the most fun thing to work with, fortunately there is a simple way to determine if a String contains another String in iOS, and it goes like this:

  NSString *interestingString = @"In the course of human events...";
  BOOL contains = ([interestingString rangeOfString:@"course"].location != NSNotFound);


Well, thank goodness that you don't need to iterate over matches, but if you do, we wrote about that too. Give us a +1 on Google, and we'll have your answer ready when you need it.
