title: Comma-separated string to NSArray in Objective-C
body: <p>So I have no experience with arrays... But I need to use one to populate a UIPickerView. I am obtaining a list of objects via HTTP (NSURLConnection). This works fine. Currently, the response is stored in a NSString as a comma-separated list. I need to convert it to an array. I think this is the type of array I need:</p>
  
  <pre><code>NSArray  * myArray2 = [NSArray arrayWithObjects:@"foo",@"bar",@"baz",nil];
  </code></pre>
  
  <p>Maybe I'm overcomplicating things... I'm really not sure. There is already an array for the PickerView, and I have it setup so to add an item to the PickerView array I use this code:</p>
  
  <pre><code>[pickerArray addObject:@"Item 1"];
  </code></pre>
  
  <p>So... How do I separate the items in a comma-separated string (item 1,item 2,item 3,...) into separate array items ([pickerArray addObject:@"item 1"];)??</p>
