    <p>I have implemented a MGSplitViewController where I have 6 rows in the masterviewcontroller and each one loads a new UIViewController into the detailviewcontroller - I have followed Apples example project on using multiple detail view controllers. But I am having a couple of weird problems with it.</p> <p>Firstly, upon the initial load the first selected detailviewcontroller displays perfectly. However, when I select different rows in the masterviewcontroller to change the detail view controller the row is selected but the detailviewcontroller does not change - this continues on like this for several clicks - then everything works fine.</p> <p>Well almost, now when the new detailviewcontroller actually loads sometimes the views become overlaid. For instance if I first select a detailviewcontroller with a tableview and then select one that just has some buttons in it - the buttons appear overlaid onto of the tableview. If anyone can understand what I am doing wrong please let me know. Here is my did selectrow method.</p> <pre><code>- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { /* Create and configure a new detail view controller appropriate for the selection. */ switch (indexPath.row) { case 1: { self.splitViewController.detailViewController = self.postViewController; // popover = [[UIPopoverController alloc] initWithContentViewController:self.postViewController]; // [popover presentPopoverFromRect:CGRectMake(200, 0, 100, 100) // inView:self.splitViewController.view // permittedArrowDirections:UIPopoverArrowDirectionAny // animated:YES]; break; } case 2: self.splitViewController.detailViewController = self.latestViewController; break; case 3: self.splitViewController.detailViewController = self.categoriesViewController; break; case 4: self.splitViewController.detailViewController = self.messagesViewController; break; case 5: self.splitViewController.detailViewController = self.searchViewController; break; case 6: self.splitViewController.detailViewController = self.accountViewController; break; default: break; } } </code></pre>

    1. COI suppose you're not using ARC with your app. Don't you want to remove the previous detailViewController from the superview before assigning a new one? What are your properties of all the detailViewControllers?

    2. COSorry, I am using ARC. How would I remove them? I tried to set them to nil but get a compiler error. All of the detailViewControllers are UINavigationControllers that are (nonatomic, strong).

    3. CONo, with ARC you don't need to release them, but before assigning a new detailview, you could try something like `if (self.splitViewController.detailViewController) [self.splitViewController.detailViewController.view removeFromSuperview];`

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
