如何延迟应用程序加载以显示启动画面更长时间？

在app委托中我放了一些函数,我希望启动画面等到appdelegate完成其功能.现在,我的应用程序立即运行初始视图控制器func和app委托func.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    let email = NSUserDefaults.standardUserDefaults().stringForKey("userEmail")
    if let email = email {
       reLogin()
    }else{
        buildNavigationDrawer()
    }// I want this execute first and run the initial view controller's after

    return true
}

这该怎么做？或者这是关闭初始视图控制器的方法？
