【英文标题】：in react native camera onGoogleVisionBarcodesDetected not working on IOS

【问题描述】：

在反应原生相机中，我正在使用onGoogleVisionBarcodesDetected 不会在 ios 上触发 在android上工作，但不在ios上

在安装要求中我应该在pod文件中添加这个

pod 'react-native-camera'，路径：'../node_modules/react-native-camera'，子规范：[ '条形码检测器MLKit' ]

但是当我尝试安装 pod 时发生了这个错误

require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
require_relative '../node_modules/react-native/scripts/react_native_pods'
platform :ios, '10.0'
target 'megatel' do
  config = use_native_modules!
  use_react_native!(:path => config["reactNativePath"])
   # react-native-maps dependencies
   rn_maps_path = '../node_modules/react-native-maps'
   pod 'react-native-google-maps', :path => rn_maps_path
   pod 'GoogleMaps'
   pod 'Google-Maps-iOS-Utils'
   pod 'GoogleMLKit/BarcodeScanning'
     permissions_path = '../node_modules/react-native-permissions/ios'
   pod 'Permission-Camera', :path => "#permissions_path/Camera.podspec"
   pod 'Permission-LocationAlways', :path => "#permissions_path/LocationAlways.podspec"
   pod 'Permission-PhotoLibrary', :path => "#permissions_path/PhotoLibrary.podspec"
   pod 'GoogleMLKit/BarcodeScanning'
   pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
    'BarcodeDetectorMLKit'
  ]
  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)
  end
end
target 'megatel-tvOS' do
  # Pods for megatel-tvOS
  target 'megatel-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end
end

“反应”：“16.9.0”， “反应原生”：“^0.63.3”， "react-native-camera": "^3.40.0",

【问题讨论】：

你找到解决办法了吗？

【参考方案1】：

我昨天能够让它在 Mac 上运行。 使用onGoogleVisionBarcodesDetected 扫描速度要快得多。 我只是像你一样将片段添加到 Podfile 中：

pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
  'BarcodeDetectorMLKit'
]

然后运行pod update。

使用的版本是：

CocoaPods 1.10.1
react 17.0.2
react-native 0.64.2
react-native-camera 4.1.1
GoogleMLKit 2.3.0
MLImage 1.0.0-beta1
MLKitBarcodeScanning 1.4.0
MLKitCommon 3.1.0
MLKitVision 1.3.0
