【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。
【讨论】:
【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。
