ios - 单击带有 Reveal 的推送通知导航到特定 View

Question

我想在单击推送通知时导航到特定的 View Controller 。

我已经在我的 didReceiveRemoteNotification 方法中编写了这段代码。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "deals") as! FYIDealsVC
        let naviVC:UINavigationController? = self.window?.rootViewController?.revealViewController().frontViewController as? UINavigationController
        naviVC?.pushViewController(vc, animated: true)
}

但它给了我这个使应用程序崩溃的错误。

fatal error: unexpectedly found nil while unwrapping an Optional value

有很多帖子介绍了导航 Controller 或只是介绍了 View Controller 。但我想使用 reveal 导航到特定 View 。

如有任何帮助，我们将不胜感激。

Answer 1

这是另一个解决方案试试这个:-

第一个选项:-

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
     let vc = storyboard.instantiateViewController(withIdentifier: 
    "deals") as! FYIDealsVC

  // setup revelview controller and root with window 

    self.window?.rootViewController = //object of revelViewController
    self.window?.makeKeyAndVisible()

第二个选项:-

 //  in Landing Screen from where you can easily navigate to the target 
  viewcontroller :- 

在 Landing VC 中:-

   viewdidload:- 
            NotificationCenter.default.addObserver(self, selector: 
    #selector(self.navigationForNotification(notification:)), name: 
   NSNotification.Name(rawValue:PushNavigationIdentifier), object: nil)


// Selector Method :-

 func navigationForNotification(notification:Notification) {
  let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: 
 "deals") as! FYIDealsVC
 self.navigationController?.pushViewController(vc, animated: true)  
}


 in appDelegate :- 
   func application(_ application: UIApplication, 
   didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
                  NotificationCenter.default.post(name: 
   NSNotification.Name(PushNavigationIdentifier), object: userInfo)

   }
