添加许多视图控制器

Question

如何从appDelegate接收不同的值？

@synthesize window;
@synthesize viewController;
@synthesize viewController2;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {   

    [self.window addSubview:viewController2.view];
    [self.window addSubview:viewController.view];

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
        if (choix==6) {
            XMLTestAppDelegate   *appDelegatess = (BroseFormular2*)[[UIApplication sharedApplication] delegate];
            appDelegatess.viewController2.detailItem =[listOfMovies objectAtIndex:indexPath.row];
        }
        else if (choix==7)              
        {
            XMLTestAppDelegate   *appDelegate = (BroseFormular2*)[[UIApplication sharedApplication] delegate];
            appDelegate.viewController2.detailItem =[listOfMovies objectAtIndex:indexPath.row];
        }           
        else {              
            NSLog(@"no");
            XMLTestAppDelegate   *appDelegates = (authe*)[[UIApplication sharedApplication] delegate];
            appDelegates.viewController.detailItem =[listOfMovies objectAtIndex:indexPath.row];                 
        }

iPhone上的窗口中应该只有一个视图控制器。一次只能有一个控制器控制视图。

这将是一个问题：

[self.window addSubview:viewController2.view];
[self.window addSubview:viewController.view];

[编辑]实际上，有些情况下你可以在iPad上激活两个视图控制器，例如你可以在弹出视图中有一个视图控制器。
