NSMutableArray - Get Arrays Index Integer By Searching With A String

Question

I have been working with NSMutableArray and have had no problems retrieving an object from an array by using `objectAtIndex:int`. 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. ``` 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) ``` 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.

Accepted Answer

You can use the `indexOfObject:` method from `NSArray`:

```
NSUInteger index = [animalOptions indexOfObject:@"Bear"];
```

If there are duplicate entries then the lowest index of that object is returned. For more information, take a look at the docs.
