升级到iOS 4.2后，iPhone / iPad应用程序在Ipad上显示空白屏幕

Question

Since I've upgraded my iPad to iOS 4.2, one of my universal applications shows a blank screen on iPad (on iPhone, it's OK).

The code creating the window for the iPad is:

firstVC = [[[PickerViewController alloc]             initWithNibName:@"PickerViewIpad" bundle:nil] autorelease];
ResultViewController* secondVC = [[[ResultViewController alloc]
            initWithNibName:@"ResultViewIpad" bundle:nil] autorelease];

PermanentSplitViewController* splitVC = [[PermanentSplitViewController alloc] init];
  splitVC.viewControllers = [NSArray arrayWithObjects:firstVC, secondVC, nil];

[window addSubview:splitVC.view];
[window makeKeyAndVisible];

PermanentSplitViewController is derived from UISplitViewController.

No fatal error at compilation. No error at runtime.

Any idea how to solve this problem?

The problem was not in the creation of the views but is similar as this one : How implement splitview for iphone os 4.2?
