Question

我使用以下方法获取当前viewController但它始终返回SWRevealViewController作为currentController。

我使用SWRevealViewController来处理幻灯片菜单。

extension UIApplication {
  class func topViewController(base: UIViewController) -> UIViewController?{
    if let nav = base as? UINavigationController {
        return topViewController(nav.visibleViewController!)
    }
    if let tab = base as? UITabBarController {
        if let selected = tab.selectedViewController {
            return topViewController(selected)
        }
    }
    if let presented = base.presentedViewController {
        return topViewController(presented)
    }
    return base
  }
}

以下是我试图获取当前控制器的方法：

 let topVC = UIApplication.topViewController(((UIApplication.sharedApplication().delegate as! AppDelegate).window?.rootViewController)!)
    print(topVC)
    if topVC!.isKindOfClass(mycontroller) == false{
        //do something
    }else{
     // do another thing
    }
}

尝试像这样获取当前视图控制器：

   UIViewController *topController = self.window.rootViewController;
     while (topController.presentedViewController) {
     topController = topController.presentedViewController;
}

SWRevealViewController获取currentController时出现问题
