I have a plist file like this

<array>

    <array>

        <dict>

            <key>name</key>

            <string>Ryan</string>

            <key>image</key>

            <string>088i.png</string>

            <key>webSiteURL</key>

            <string>http://www.ryan.com</string>

            <key>category</key>

            <string>Monday</string>

        </dict>

    </array>

    <array>

        <dict>


            <key>name</key>

            <string>Pinky</string>
            <key>image</key>

            <string>089i.png</string>

            <key>webSiteURL</key>

            <string>http://www.pinky.com</string>

            <key>category</key>

            <string>Sunday</string>


        </dict>

        <dict>


            <key>name</key>

            <string>Kitty</string>

            <key>image</key>

            <string>098i.png</string>

            <key>webSiteURL</key>

            <string>http://www.kitty.com</string>

            <key>category</key>

            <string>Sunday</string>


        </dict>

    </array>

</array>

This plist will be load to a NSTableView as a NSMutableArray, Now I want to pass data to DetailView, how to get specific data actually?

I use

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([[segue identifier] isEqualToString:@"TableToWebSegue"]) {
        NormalDetailView *detailViewController = [segue destinationViewController];

        detailViewController.webSiteURL = [[_cellContentList objectAtIndex:indexPath.row] objectForKey:@"webSiteURL"]
    } }

But it said indexPath is wrong and should be NSIndexPath, I change it to NSIndexPath but it said .row is wrong…

This is my first app, I have no idea how to get data in this case, if I want get webSiteURL, how to do it? How to pass it to detail view?

Answer 1

If your prepareForSegue method is in the UITableViewController that is you master controller, then just add this line to your prepareForSegue method:

 NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];

Then, you can use indexPath.row like you have it in your post.

After Edit: In response to your comments, I took a look at your project, and the error is occurring on lis line in NormalViewController:

detailViewController.name = [[_cellContentList objectAtIndex:indexPath.row] objectForKey:@"name"];

The problem is, that [_cellContentList objectAtIndex:indexPath.row] is a NormalCategory object which doesn’t have an objectForKey: method. It has a normalList property, which in itself has 2 normalData objects, which in turn have a “name” property. I assume it’s that name property you’re trying to get to, but which one? Since there are 2 normalData objects, you have to have a way to pick which one you want. It seems to me that your data structure is overly complex and confusing (at least to me).
