React Native：如何检测带有 Notch 的 iPhone？

我正在尝试举一个具体的案例iPhone Xs Max in react native?

这就是我的代码IphoneX from 反应本机 iphone-x-helper https://www.npmjs.com/package/react-native-iphone-x-helper

export function isIphoneX() {
    let dimen = Dimensions.get('window');
    return (
        Platform.OS === 'ios' &&
        !Platform.isPad &&
        !Platform.isTVOS &&
        (dimen.height === 812 || dimen.width === 812)
    );
}

尺寸是多少iPhone Xs Max只需添加以下就足够了iPhone Xs Max方面？

最后我选择了这个：

    export function isIphoneXorAbove() {
      const dimen = Dimensions.get('window');
      return (
        Platform.OS === 'ios' &&
        !Platform.isPad &&
        !Platform.isTVOS &&
        ((dimen.height === 812 || dimen.width === 812) || (dimen.height === 896 || dimen.width === 896))
      );
    }

但所有的功劳都归功于此PR https://github.com/ptelad/react-native-iphone-x-helper/pull/9

EDIT:如果您希望此函数适用于 iPhone 11 和 iPhone 12 版本，您可以使用此函数：

function isIphoneWithNotch() {
  const dimen = Dimensions.get('window');
  return (
    Platform.OS === 'ios' &&
    !Platform.isPad &&
    !Platform.isTV &&
    (dimen.height === 780 ||
      dimen.width === 780 ||
      dimen.height === 812 ||
      dimen.width === 812 ||
      dimen.height === 844 ||
      dimen.width === 844 ||
      dimen.height === 896 ||
      dimen.width === 896 ||
      dimen.height === 926 ||
      dimen.width === 926)
  );
}

EDIT 2:最后，我采用了一种更干净的方法，使用反应本机设备信息 https://github.com/react-native-device-info/react-native-device-info

const deviceId = DeviceInfo.getDeviceId();
const iphonesWithNotch = [
  'iPhone10,3',
  'iPhone11,2',
  'iPhone11,4',
  'iPhone11,6',
  'iPhone11,8',
  'iPhone12,1',
  'iPhone12,3',
  'iPhone12,5',
  'iPhone12,8',
  'iPhone13,1',
  'iPhone13,2',
  'iPhone13,3',
  'iPhone13,4',
  'iPhone14,2',
  'iPhone14,3',
  'iPhone14,4',
  'iPhone14,5',
  'iPhone14,6',
  'iPhone14,7',
  'iPhone14,8',
];

const isIphoneWithNotch = iphonesWithNotch.includes(deviceId);

或者更简单：

let hasNotch = DeviceInfo.hasNotch();
