body: <p>Not sure why I get "Missing sentinel in function call?"</p>
  
  <pre><code>NSMutableArray *kkk = [NSMutableArray arrayWithObjects: @"a", @"b", @"cat", @"dog", nil];
  ppp = [NSMutableArray arrayWithCapacity:3];
  [ppp addObject:[[NSMutableArray alloc] initWithObjects: kkk]]; // &lt;&lt;--- Missing sentinel in function call
  [ppp addObject:[[NSMutableArray alloc] initWithObjects: kkk, nil]]; //&lt;&lt;--- change, but it falls out
  
  NSLog(@"Working: %@   %@", [[ppp objectAtIndex:0] objectAtIndex:3], [[ppp objectAtIndex:0] objectAtIndex:2] );
