通过可可豆荚安装第三方框架后出现“reachabilityChanged”错误？

【中文标题】通过可可豆荚安装第三方框架后出现“reachabilityChanged”错误？

【英文标题】：Getting Ambiguous use of 'reachabilityChanged' error after installing third party framework through cocoa pods?

【发布时间】：2020-01-24 13:14:18

【问题描述】：

我有以下互联网连接检查代码，使用 rechability 在我的应用程序中的互联网连接状态发生变化时发出通知。

self.reachability = Reachability.forInternetConnection();
self.reachability.startNotifier();
NotificationCenter.default.addObserver(self, selector: #selector(self.checkForReachability(notification:)), name: Notification.Name.reachabilityChanged, object: reachability)

之前它工作正常，但在通过可可豆荚添加第三方框架后，我收到以下错误。 'reachabilityChanged' 的模糊使用

如果我将其更改为以下代码，则如某些网站/博客中所建议的那样

NotificationCenter.default.addObserver(self, selector: #selector(self.checkForReachability(notification:)), name: Notification.Name("reachabilityChanged"), object: nil)

然后错误得到解决，但是当互联网连接发生变化时，它不会通知并且 checkForReachability 方法不会被调用。

如何解决此问题。 注意：我不知道是哪个第三方框架/文件导致了这个问题

我正在使用 swift 5

以下是我的 pod 文件

【问题讨论】：

您将哪些库添加为 cocoapods？

你试过下面的swift 4 / swift 5 answer

***.com/a/30743763/2303865的可能重复

【参考方案1】：

当我将 ReachabilitySwift pod 库文件中的通知reachabilityChanged 名称更改为其他名称时，我没有收到构建错误，并且当网络状态更改时 checkForReachability 方法也被调用。

但是在 podfile 中更改某些内容并不是一个好的解决方案，因为如果每次我们需要更新 pod，所以我删除了 ReachabilitySwift pod 文件并使用了 alamofire 库的网络管理器。

似乎 almorfire 和外部使用的可达性导致了问题。

【参考方案2】：

我同时安装了 Reachability 和 ReachabilitySwift pod。我删除了 ReachabilitySwift pod，然后从我的 appDidFinishLaunching 方法中使用了以下代码 sn-p

func startReachability() 
    self.reachability = Reachability.forInternetConnection() //reachability has strong reference.
    NotificationCenter.default.addObserver(forName: NSNotification.Name(rawValue: "kReachabilityChangedNotification") , object: nil, queue: OperationQueue.main)  (noti) in
        let r = noti.object as! Reachability
        DispatchQueue.main.async 
            let alert = UIAlertController(title: "Success!", message: "\(r.isReachable())", preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "Ok", style: .default, handler:  (action) in

            ))
            self.window?.rootViewController?.present(alert, animated: true, completion: nil)
        
    
    self.reachability.startNotifier()

这对我有用。其他组合对我不起作用。 NSNotification 的块/选择器没有被调用，但是当我使用上面的 sn-p 时它确实被调用了。
