title: Finding a substring in a NSString object
body: <p>I have an NSString object and I want to make a substring from it, by locating a word.</p>
  
  <p>For example, my string is: "The dog ate the cat", I want the program to locate the word "ate" and make a substring that will be "the cat".</p>
  
  <p>Can someone help me out or give me an example?</p>
  
  <p>Thanks,</p>
