Question

I am using an NSMutableArray to hold some objects, and I need to access the element at i and the element at i+1 in the same line. Also, is there any way to access the NSMutableArray‘s length?

Answer 1

Try this:

for(int i = 0; i < [arry count]; i++)
{
  [arry objectAtIndex:i];
  [arry objectAtIndex:i+1];
}

As for your second question, yes, use the selector count. I think you need to spend some time with the NSMutableArray documentation.
