Question

I’m working on a project for iOS5 using xcode.
ARC is ON
Using the storyboard

I have a class named Event which contains event info.
I have a TableView on the storyboard linked to my ListViewController.m file
I also made a view on the storyboard called ‘Detail’ and a DetailViewController.m file (which it is linked to)

Currently in my ListViewController.m I used this function:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    DetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];
    [self.navigationController pushViewController:detail animated:YES];
}

The items in the listview are made up from a var from the listviewcontroller, named events.

What I want to do is when I init the detailview, I want to pass the event coupled to that list item with it so I can fill up the text from the labels with the correct information in my DetailViewController.m.

I would like to do it like this cause I will also have other representations for the events (on a map, …) and would like to use this detail view for all of them.

How to best set this up?

Answer 1

Add an ‘Event’ property on your ‘DetailViewController’ and assign it to the controller before doing the push:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //Get here the selected event fron the datasource and assign it to yourSelectedEvent

    DetailViewController *detail = [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];

    [detail setEvent: yourSelectedEvent];

    [self.navigationController pushViewController:detail animated:YES];
}

Then you can use it to put the text to the labels.
