How to get contacts from phone using react native expo

Question

使用 react native expo 从电话中获取联系人我没有得到它

Answer 1

Use Contacts and Permissions, get user permission and then take the data as stated in the Expo docs . Here is an example: Snack Contact Example

async showFirstContactAsync() {
  // Ask for permission to query contacts.
  const permission = await Permissions.askAsync(Permissions.CONTACTS);

  if (permission.status !== 'granted') {
    // Permission was denied...
    return;
  }
  const contacts = await Contacts.getContactsAsync({
    fields: [
      Contacts.PHONE_NUMBERS,
      Contacts.EMAILS,
    ],
    pageSize: 10,
    pageOffset: 0,
  });
  if (contacts.total > 0) {
    Alert.alert(
      'Your first contact is...',
      `Name: ${contacts.data[0].name}\n` +
      `Phone numbers: ${contacts.data[0].phoneNumbers[0].number}\n` +
      `Emails: ${contacts.data[0].emails[0].email}`
    );
  }
}
