Question

I’m trying to make segue via IB, that switching views when pressed cell accessory in tableView.

Images from my IB:

1.I’m dragging from cell of tableviewcontroller to another view and selecting Accessory Action -> push

and when i’m running my project i get error:

[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key accessoryActionSegueTemplate

I think that this might be something wrong with reuseIdentifier of cell.

My cellForRowAtIndexPath: method:

static NSString *CellIdentifier = @"champion cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

NSString *cellIconName = ((championList *)[self.champions objectAtIndex:indexPath.row]).championImage;
UIImage *cellIcon = [UIImage imageNamed:cellIconName];
[[cell imageView] setImage:cellIcon];

cell.imageView.frame = CGRectMake(0.0f, 0.0f, 70.0f, 70.0f);

cell.imageView.layer.cornerRadius = 7;
[cell.imageView.layer setMasksToBounds:YES];

cell.textLabel.text = ((championList *) [self.champions objectAtIndex:indexPath.row]).championName;
cell.detailTextLabel.text = ((championList *) [self.champions objectAtIndex:indexPath.row]).championId;

return cell;

I can use performSegueWithIdentifier: method as solution of this problem, but i want to figure out why i having problem with accessory action in IB.

Answer 1

I had this problem when I had ctrl-dragged a segue from the detail accessory button of the prototype cell to the next view controller. So instead I did the drag from the table view controller itself, and added a bit of code to it.

Objective-C:

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier: @"EditUser" sender: [tableView cellForRowAtIndexPath: indexPath]];
}

Swift 3.0:

func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {
    performSegue(withIdentifier: "EditUser", sender: tableView.cellForRow(at: indexPath))
}

This works for iOS 5.0 – 10.x
