title: NSMutableArray - Get Arrays Index Integer By Searching With A String
body: <p>I have been working with NSMutableArray and have had no problems retrieving an object from an array by using <code>objectAtIndex:int</code>.  Rather then pulling an object out of the array by an integer is their a way to get the index position by searching the array with a string.</p>
  
  <pre><code>animalOptions = [[NSMutableArray alloc] init]; 
  //Add items
  [animalOptions addObject:@"Fish"];
  [animalOptions addObject:@"Bear"];
  [animalOptions addObject:@"Bird"];
  [animalOptions addObject:@"Cow"];
  [animalOptions addObject:@"Sheep"];
  
  NSString * buttonTitle = [animalOptions objectAtIndex:1];
  // RETURNS BEAR
  
  int * objectIndex = [animalOptions object:@"Bear"];
  // THIS IS WHAT I NEED HELP WITH, PULLING AN INDEX INTEGER WITH A STRING (ex: Bear)
  </code></pre>
  
  <p>Hopefully this makes sense, and there is an answer out there, I have been unable to research online and find anything through google or apple's class references.</p>
