Question

I have this in my tableView:cellForRowAtIndexPath:

if (condition) {
    // make a custom cell
    return cell;  // line number 240
}
else {
    // make another kind of cell
    return cell;  // line number 256
}

I got a EXC_BAD_ACCESS, so I fired up the debugger and set a breakpoint, stepping through the code line by line.

When I stepped forward “step over” from line number 256 it went directly to line 240, i.e. into another branch of the if statement. How is that possible???

Thanks a lot for your help,
Sascha

I think I found the solution. The view controller with the table view is also the delegate of a background web loading thread. Apparently the debugger can only step through one thread at a time. The delegate routine did indeed call a scrollToRowAtIndexPath: without checking the above condition.

Still, I find the behavior of the debugger a bit puzzling.
