Expo 联系人（旧版）

提供对手机系统联系人的访问的库。

Android

iOS

Included in Expo Go

Recommended version:

~57.0.0

重要 legacy 版本的 Contacts API 已包含在 expo-contacts 库中。它可以与从根导出的基于类的 expo-contacts API 一起使用。要使用传统 API，请从 expo-contacts/legacy 导入。

expo-contacts 提供对设备系统联系人访问的功能，允许你获取联系人信息，以及添加、编辑或删除联系人。

在 iOS 上，联系人有一个多层分组系统，你也可以通过此 API 访问该系统。

🌐 On iOS, contacts have a multi-layered grouping system that you can also access through this API.

安装

🌐 Installation

Terminal

- npx expo install expo-contacts

If you are installing this in an existing React Native app, make sure to install expo in your project.

应用配置中的配置

🌐 Configuration in app config

如果你在项目中使用配置插件（连续原生生成 (CNG)），可以使用其内置的配置插件来配置 expo-contacts。该插件允许你配置无法在运行时设置并且需要构建新的应用二进制文件才能生效的各种属性。如果你的应用不使用 CNG，则需要手动配置该库。

🌐 You can configure expo-contacts using its built-in config plugin if you use config plugins in your project (Continuous Native Generation (CNG)). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect. If your app does not use CNG, then you'll need to manually configure the library.

Example app.json with config plugin

app.json

{
  "expo": {
    "plugins": [
      [
        "expo-contacts",
        {
          "contactsPermission": "Allow $(PRODUCT_NAME) to access your contacts."
        }
      ]
    ]
  }
}

Configurable properties

Name	Default	Description
`contactsPermission`	`"Allow $(PRODUCT_NAME) to access your contacts"`	Only for: iOS A string to set the `NSContactsUsageDescription` permission message.

Are you using this library in an existing React Native app?

如果你没有使用连续原生生成（CNG）（而是手动使用原生 Android 和 iOS 项目），那么你需要在原生项目中配置以下权限：

🌐 If you're not using Continuous Native Generation (CNG) (you're using native android and ios projects manually), then you need to configure following permissions in your native projects:

对于 Android，在项目的 android/app/src/main/AndroidManifest.xml 中添加 android.permission.READ_CONTACTS 和 android.permission.WRITE_CONTACTS 权限：
```
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
```

对于 iOS，在你的项目 ios/[app]/Info.plist 中添加 NSContactsUsageDescription 键：

<key>NSContactsUsageDescription</key>
<string>Allow $(PRODUCT_NAME) to access your contacts</string>

用法

🌐 Usage

Basic Contacts Usage

import { useEffect } from 'react';
import { StyleSheet, View, Text } from 'react-native';
import * as Contacts from 'expo-contacts/legacy';

export default function App() {
  useEffect(() => {
    (async () => {
      const { status } = await Contacts.requestPermissionsAsync();
      if (status === 'granted') {
        const { data } = await Contacts.getContactsAsync({
          fields: [Contacts.Fields.Emails],
        });

        if (data.length > 0) {
          const contact = data[0];
          console.log(contact);
        }
      }
    })();
  }, []);

  return (
    <View style={styles.container}>
      <Text>Contacts Module Example</Text>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

When the query produces a single result, the contact access button shows the caption under the matching contact name. It can be nothing (default), email address or phone number.

Acceptable values are: 'default' | 'email' | 'phone'

`ignoredEmails`

iOS 18.0+

Optional • Type: string[]

An array of email addresses. The search omits contacts matching query that also match any email address in this array.
