Question

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.

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.

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.

- (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;
    }
}

There seems to be a bug in MGSplitViewController where it doesn’t remove the previous detailViewController’s view. To solve this, add the following line above your switch statement:

[self.splitViewController.detailViewController.view removeFromSuperview]
