Different Views for Each Cell

So I am re-creating the treehouse blog reader app for practice and for the first view that comes up when you launch the app is a table view of the following categories: Websites, Coding, iOS, Andriod and Business. Now I can't seem to figure out how to perform a segue based on the category selected. When I click on any of them each one has the same view, but I want it to have different views. Any help would be much appreciated, thanks!

You need to get the indexPath to the correct cell (i.e the one that was tapped). In your prepareForSegue method, one of the arguments is (id)sender. Do something like this to get the indexPath:

NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];

Hey Thomas Nilsensender { if ([segue.identifier isEqualToString:@"showCategories"]) { NSIndexPath *indexPath = [self.tableView indexPathForCell:0]; [self.carSites objectAtIndex:indexPath.row]; }

}

You're using storyboards. Are you absolutely 100% sure that all the segues in you storyboard are connected properly? If yes, could you provide a dropbox link to the project so I can have a look?

I don't have a drop box link, but maybe I'm setting it up wrong? I select the yellow box under the view controller in the storyboard and ctrl drag to the tableview I want. In the tableview's implementation file I declare the array I want displayed. But since I'm not actually dragging it from the cell how do I tell the specific cell selected to take that segue path?

Thomas Nilsen I even tried the following code

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    if ([indexPath row] == 0) {
        [self performSegueWithIdentifier:@"viewAndriod" sender:nil];
    }
}

In my mind this should work, although I'm used to doing everything programmatically. I would really be helpful if you could zip the project and mail it to me: thnilsen90@gmail.com, or upload it to github or something :)
