本文介绍了NSNetServiceBrowser 在 iOS 14 上没有搜索错误 -72008的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

设置多点连接(使用 Bonjour)也会触发相同的错误.我用于启动 Bonjour 浏览和 Multipeer Connectivity 的代码是从 Apple 示例代码修改而来的，并且在 iOS 13 下运行良好.

The same error is also triggered setting up Multipeer Connectivity (which uses Bonjour). The code I was using for initiating Bonjour browsing and Multipeer Connectivity was modified from the Apple sample code and worked fine under iOS 13.

推荐答案

您需要在 Info.plist 中添加以下键:NSLocalNetworkUsageDescription 和 NSBonjourServices.例如

You need to add the following keys to the Info.plist:NSLocalNetworkUsageDescription and NSBonjourServices.E.g.

<key>NSLocalNetworkUsageDescription</key>
<string>Reason for using Bonjour that the user can understand</string>
<key>NSBonjourServices</key>
<array>
    <string>_my-service._tcp</string>
    <string>_my-service._udp</string>
</array>

确保为您的服务名称正确命名了 my-service.例如.如果您正在为 foobar" 服务设置 MPC，您可能有

Ensure that my-service is correctly named for your service name. E.g. if your are setting up MPC for a "foobar" service, you might have

mpcAdvertiserAssistant = MCAdvertiserAssistant(serviceType: "foobar", discoveryInfo: discoveryInfoDict, session: mpcSession)

所以你会使用

<string>_foobar._tcp</string>
<string>_foobar._udp</string>

(您的实现中可能不需要 TCP 和 UDP.)

(You might not require both TCP and UDP in your implementation.)
