Why am I getting an isEqualToString error in this Cocoa code?

Question

I keep getting this error:

alt text http://img514.imageshack.us/img514/2203/help.tif

What is it? I never even called \"isEqualToString\".

Here Is my Joke

Answer 1

Replace this line:

cell.text = [jokes objectAtIndex:indexPath.row];

with these lines:

Joke *j = (Joke *)[jokes objectAtIndex:indexPath.row];
if( j )
  cell.text = j.joke;
