Can’t add UIImagePickerViewController’s view as a sub view – iOS 4

Incorrect code sample

UIImagePickerController *pickerController = [[UIImagePickerController alloc]init];
pickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
pickerController.delegate = self;
[self.navigationController.view addSubview:pickerController];
[pickerController release];

Actually there is nothing wrong with the addSubview method. The only problem is that it doesn’t load the gallery.
