Question

I have a navigation view controller that will show the table view of my application, but I can’t get it to move to a new view when I tap an entry in the table. How do I link a new view to an element in the parent view?

Answer 1

You have a navigation view controller?

You either have a navigation controller or a view controller.

A navigation controller has a stack of view controllers and pushes and pops between them.

In regards to your question you need to define the tableview’s delegate as self. If you’re subclassing UITableViewController then you don’t have to worry about this.

Then implement this method:

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

    // here is where you can "push" a new view controller
    MyNextViewController *nextVC = [[MyNextViewController alloc] initWithNibName:@"MyNextViewController" bundle:nil];
    [nextVC setTitle:@"Next View Controller"];
    [self.navigationController pushViewController:nextVC animated:YES]; // this is where the next page is "pushed"
    // remember to release
    [nextVC release];

}

So in the code above we’re using the delegate method didSelectRowAtIndexPath which gets called when the user “clicks” a table view cell.

You can use the indexPath object to find out which row was tapped. int rowIndex = [indexPath row]; will get you the row index of the cell that was tapped.
