ios - 迁移到 x64 iOS 后的 Xamarin NetworkReachability SetCallBack 方法问题

Question

将我的 iOS 项目迁移到 x64 后，我遇到了很多错误，我修复了所有错误，但我无法修复以下错误，我在 Xamarin 和 Apple 开发者网站上搜索了很多，但没有解决。

Error CS1061: Type `SystemConfiguration.NetworkReachability' does not contain a definition for `SetCallback' and no extension method `SetCallback' of type `SystemConfiguration.NetworkReachability' could be found. Are you missing an assembly reference? (CS1061)

我还导入了以下引用资料:

using System;
using System.Net;
using Foundation;
using UIKit;
using SystemConfiguration;
using CoreFoundation;
using CoreServices;

代码是:

NetworkReachability reachability = new NetworkReachability (new IPAddress (new byte [] {169,254,0,0}));
reachability.SetCallback (OnChange); // <-- seems that this method removed from the class But what I should use instead of it ?

请与我分享您的建议。

Answer 1

您需要改用 reachability.SetNotification()。

SetCallback() 不再推荐:

[Advice ("Use SetNotification instead")]
public bool SetCallback (NetworkReachability.Notification callback)
{
    return this.SetNotification (callback) == StatusCode.OK;
}
