无法读取未定义的属性 getPermissionStatus |反应本机权限 [英] Cannot read property getPermissionStatus of undefined | react-native-permissions

问题描述

使用

我直接使用 react-native-permissions README 中的代码

 componentWillMount() {Permissions.check('photo').then(response => {控制台日志(响应)；});}

我使用 react-native link 来链接它.

react-native 链接 react-native-permissions

我很确定它链接正确，因为当我调用 Permissions.getTypes()

componentWillMount() {console.log(Permissions.getTypes());}

我收到以下回复:

React 原生版本: 0.53.0

React Native 权限版本: 1.1.1

Podfile

# 取消下一行的注释，为你的项目定义一个全局平台平台:ios，'10.0'目标myApp"做pod '条纹', '~>11.2.0'pod 'RNVectorIcons', :path =>'../node_modules/react-native-vector-icons'pod 'BVLinearGradient', :path =>'../node_modules/react-native-linear-gradient'pod 'ReactNativePermissions', :path =>'../node_modules/react-native-permissions'结尾

编辑

• 我将 React Native 降级为 0.52.0，因为这是 react-native-permissions 更新自述文件的最后一次，但我仍然遇到相同的错误.

解决方案

事实证明，

Permissions.getTypes()

无需链接即可工作.

我最终不得不按照此处的手动链接说明进行操作:使用手动链接

<块引用>

使用手动链接

在 XCode 的项目导航器"中，右键单击项目的库文件夹 ➜ 将文件添加到 <...>转到 node_modules ➜ react-native-permissions ➜ 选择 ReactNativePermissions.xcodeproj将 libReactNativePermissions.a 添加到构建阶段 ->将二进制文件与库链接

I'm getting this error when calling Permissions.check() using the react-native-permissions library

I'm using the code straight from the react-native-permissions README

  componentWillMount() {
    Permissions.check('photo').then(response => {
        console.log(response);
    });
}

I used react-native link to link it.

react-native link react-native-permissions

I'm pretty sure it's linked correctly because when I call Permissions.getTypes()

componentWillMount() {
    console.log(Permissions.getTypes());
}

I get the following response:

React Native Version: 0.53.0

React Native Permissions Version: 1.1.1

Podfile

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'

target 'myApp' do
  pod 'Stripe', '~> 11.2.0'
  pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'

  pod 'BVLinearGradient', :path => '../node_modules/react-native-linear-gradient'

  pod 'ReactNativePermissions', :path => '../node_modules/react-native-permissions'

end

Edits

• I downgraded React Native to 0.52.0 as that's the last react-native-permissions updated their README and I still get the same error.

解决方案

It turns out,

Permissions.getTypes()

works without linking.

I ended up having to follow the manual linking instructions here: using manual linking

Using manual linking

In the XCode's "Project navigator", right click on your project's Libraries folder ➜ Add Files to <...>

Go to node_modules ➜ react-native-permissions ➜ select ReactNativePermissions.xcodeproj

Add libReactNativePermissions.a to Build Phases -> Link Binary With Libraries
