ReactNative 获取屏幕宽高

let Dimensions = require('Dimensions');

// 示例
class KKScreen {

    static width() {
        return Dimensions.get('window').width;
    }

    static height() {
        return Dimensions.get('window').height;
    }

    static scale() {
        return Dimensions.get('window').scale;
    }
}
