在 Swift 5 中使用可达性 [重复]

Posted 2023-02-23

【中文标题】在 Swift 5 中使用可达性 [重复]

【英文标题】：Using Reachability in Swift 5 [duplicate]

【发布时间】：2019-05-06 19:01:47

【问题描述】：

我按照本教程尝试在我的项目中安装和使用 Reachability (https://medium.freecodecamp.org/how-to-handle-internet-connection-reachability-in-swift-34482301ea57)

它表明它已全部安装，但我的 Import 语句仍然出错。

下图显示了 Podfile、Pod 安装过程、项目目标名称和错误。

任何想法我错过了什么？我需要检测连接类型（3G、4G、Wifi 等）

NetworkStatus.swift 标头

import Foundation
import Reachability //No such module 'Reachability'

播客文件

Dans-MacBook-Pro:gnccapp danpalmer$ cat Podfile
# Uncomment the next line to define a global platform for your project
  platform :ios, '12.2'

target 'gnccapp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for gnccapp
  pod 'ReachabilitySwift'
  pod 'Alamofire'

end

Pods的安装过程

【问题讨论】：

您打开的是工作区文件而不是项目文件？

【参考方案1】：

确保您打开的是以 .xc​​workspace 而不是 .xcodeproj 结尾的文件

【讨论】：

谢谢先生，就是这样。太习惯打开项目了，我没有看到另一个。

【参考方案2】：

确保打开的是cocoapods（白色）生成的xcworkspace文件

清理构建文件夹（shift + command + K）

构建您的项目（command + B），即使出现错误。有时您必须将项目构建到 Xcode 才能了解您正在导入一些 cocoapods 框架。

希望对你有帮助
