Question

I have created an application for iPhone interface which displays a UITableView as its rootviewcontroller. When we select any of its row, it opens the corresponding detailViewController, we select the value from there and it is displayed in the cells of UITableView in masterViewController. This application was running perfectly fine in iPhone simulator as desired.

Now I want to incorporate this application to an iPad application. For that purpose, I have created a UIPopOver and assigned the masterViewController to the popover. Now the problem is, UITableView is initially shown in the popover. But when we select any row, next view doesn’t appear in popover as it appeared when application was running solely for iPhone. How should I make it work so that I can import the application with original functionality in UIPopOver?

I think you are pushing DetailViewController from your masterViewController.But your masterviewController should implement NavigationController, I mean while displaying masterViewController(your tableviewcontroller) in popover you should do as follows:

MasterViewController *theMasterViewController = [[MasterViewController alloc] init];

    UINavigationController *navCont = [[UINavigationController alloc] initWithRootViewController:theMasterViewController]; 
    [theMasterViewController release];
    UIPopoverController *popOverController = [[UIPopoverController alloc] initWithContentViewController:navCont];
    popOverController.popoverContentSize = CGSizeMake(400, 400);
    [popOverController presentPopoverFromRect:btn.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

and when user selects any row, then in didSelectRowAtIndexPath do as follows:

DetailViewController *detailViewController = [[DetailViewController alloc] init];
    [self.navigationController pushViewController:detailViewController animated:YES];
    [detailViewController release];

Hope this helps!
