I have a table view with two dynamic prototype cells. The tableview is shown using performSegue which does a modal display of a new Navigation controller. It works fine on the IOS 6.0 simulator, but not on an IOS 5.1 device (I'm using the 6.0 SDK but targeting a 5.1 platform).

I can't get the accessory view to work correctly - two problems

  1. If I add the disclosure accessory view to the dynamic table cell prototype and use the - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath tableview delegate method, it never gets called. This has been asked elsewhere but no answers yet.

  2. Alternatively, if I use the storyboard editor to trigger a segue from the disclsoure accessory view, it works fine on the simulator, but crashes on the device when I attempt to dequeue the reusable cell. Crash stackdump below

I have tried deleting and recreating the scenes in storyboard thinking that they may have become corrupted, but no joy. Any suggestions would be gratefully received.

Thanks

Usually when I get the error

    this class is not key value coding-compliant for the key

It means that something is not hooked up right in the storyboard.

For example, a previously used property name is still hooked up to an element in the storyboard.

A workaround to this would be to make the segue from controller to controller in storyboard (zoomed out so it's not hooked up to a specific event) and implement:

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

Check for what cell is being selected and use 

      [self performSegueWithIdentifier:@"yourIdentifier"];

Hope it helps, good luck.
