It doesn't work when add rootController and mainView for my window
===

I've some problem when add view and controller on self.window.
Here is the code.
My BookListViewController class owns a view object named BookListView.
The problem occurs at `makeKeyAndVisible` methods.
Thanks.

    self.bookListViewController = [[bookListViewController alloc] init];
    CGRect applicationRect = [[UIScreen mainScreen] applicationFrame];
    self.bookListViewController.bookListView = [[[BookListView alloc] initWithFrame:applicationBound] autorelease];
    self.window.rootController = self.bookListViewController;
    [self.window addSubview:self.bookListViewController.bookListView];
    [self.window makeKeyAndVisible];
