如何從appdelegate切換視圖？

Question

此代碼從我的AppDelegate從我的應用程序，這不是用故事板和normaly這撥碼開關視圖 -

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex 
{ 
    if (buttonIndex == 0) 
    { 
     LN_ShowNoteVC *showVC = [[LN_ShowNoteVC alloc] init]; 
     _iconBage = _iconBage - 1; 
     showVC.number = _showP; 
     NSLog(@"showVC.number = %i", _showP); 
     _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
     _window.rootViewController = showVC; 
     [_window makeKeyAndVisible]; 
    } 
} 

現在，我重寫我的應用程序使用故事板.....這個代碼不工作...我得到黑色的窗口
