Question

I fill my tableView with random data. So i don’t know how many row i have and how to redirect it to screen i want to. I filled:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    MyClass *currentScreenElement = [self.tableRows objectAtIndex:indexPath.row];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:currentScreenElement.objectName];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:currentScreenElement.objectName];

        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

    }

    cell.textLabel.text = currentScreenElement.objectName;

    return cell;
}

And this works fine. I have a tableView with filled rows. Now i want to redirect to new screen and I doing it with:

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

    NewScreenClass *myScreen = [[NewScreenClass alloc] init];

    self.detailViewController = [[CreateView alloc] initWithScreenDef:[myScreen returnScreenFromName:@"second"]];

    [self.navigationController pushViewController:self.detailViewController animated:YES];

}

Of course i know that what I actualy do here is create the same screen for every row. But how can i redirect to screen i want to?
My currentScreenElement object contains properties: objectName (display name in tableView) and objectTarget (screen definition). Both NSString.

And my question is should i save a my currentScreenElement to row patch somehow or maybe I should catch a objectName from dislay name?

Answer 1

Why can’t you use the self.tableRows array again?

MyClass *currentScreenElement = [self.tableRows objectAtIndex:indexPath.row];
NSString *title = [currentScreenElement objectName];

It’s the same thing you did to setup that row, just use it again.
