Is the objectAtIndex start with 1 instead of 0? I use the objectAtIndex , and passing data 0, but it said that this is out of bound. So, I guess that is start at 1, am I right?

NSMutableArray is zero-indexed. However; from the docs:
If there is nothing stored in the array, accessing index 0 will fail the above test, and cause the error.
