iOS：如何在情节提要中在横向和纵向视图之间切换？

Question

In my universal application I have a master detail at the beginning. On the iPad it is just shown as a split view and when I change the interface orientation the autosizing works fine. But on the iPhone this doesn't work good enough in my detail view. So I want to have two different views for my DetailViewController that should have the exact same functionality, but I can't really get it to work properly. I tried to use two view controllers, but that didn't really do the job. I am using a storyboard by the way.

I thought I have found a solution by adding two views to my DetailViewController. Then I simply check the current orientation and set the recent view like this:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    Video *currentVideo = [[self.xmlParser videos] objectAtIndex:indexPath.row];

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
        [self.detailViewController setDetailItem:currentVideo];
    else {

        if (!self.detailViewController) {

            DetailViewController *nextController = [self.storyboard instantiateViewControllerWithIdentifier:@"Detail"];
            if ([UIDevice currentDevice].orientation == UIDeviceOrientationPortrait)
                [nextController setView:nextController.portraitView];
            else
                [nextController setView:nextController.landscapeView];
            [nextController setDetailItem:currentVideo];
            [self.navigationController pushViewController:nextController animated:YES];
        }        
    }
}

This works like it should, but now I face another problem. The two views contain exactly the same outlets, but I can only connect the outlets of either one of them to my DetailViewController class. So in one of the orientations I can't view my contents properly or I have to code everything twice what is exactly the thing I want to avoid.

Do have any ideas how I could handle this problem?

Thanks in advance

You can try adding two views inside a container view to the view controller in the Storyboard. Size one to be the portrait, the other - the landscape. Add all the controls you need to whichever view required. When the orientation changes - hide one and show the other.
