Getting "Single stepping until exit from function CALayerGetDelegate, which has no line number information." in iphone sdk

My code is as follows:

if ([dematAllocationDict count] > 0)
    {
        [dematTableV reloadData]; // debugger stops here
        dematTableV.hidden = FALSE;
    }

When I call the method , my code runs good at first time. But when I call it again then I am getting the message in console, i.e.

"Single stepping until exit from 开发者_StackOverflow中文版function CALayerGetDelegate, which has no line number information."

I tried a lot but not getting the solution. When I do continue to run the app then it gives BAD ACCESS.

Debugger stops at :

 [dematTableV reloadData];

Please help me... :(

Thanks in advance.
