H5 所有IOS手机Safari浏览器:
调用uni.getSystemInfoSync() 输出异常为 TypeError: undefined is not an object (evaluating 'd.$children[0]')
虽然uni.getSystemInfo()没有异常，但是获取不到系统信息

测试未发现问题
提供一下出问题的几个设备的机型和系统版本信息
API 返回 Promise 方式的数据格式为：
[null,{"authResult":{"scope":"scope","access_token":"access_token","openid":"openid"},"errMsg":"login:ok"}]这个文档中后续会补充说明
hoey (作者)
let defaultLang = uni.getStorageSync('lang');
if(!defaultLang){
try{
defaultLang = uni.getSystemInfoSync().language.replace(/-/g, "_");
}catch(e){
alert(JSON.stringify(e))
//alert：{"line":928, column:13702, "sourceURL":"http://192.168.1.231:8080/index.js"}
uni.getSystemInfo().then(function(e){
alert(JSON.stringify(e))
//alert：{"line":928, column:13702, "sourceURL":"http://192.168.1.231:8080/index.js"}
})
}
}
就是以上代码出问题的，H5 所有IOS手机Safari浏览器都不行，试了还几个机子，5s，6s，7plus都不行。这个代码是写在main.js的，难道是没有初始化完获取不到？不科学啊

Android机下的 alert结果是
[null,{"windowTop":0,"windowBottom":50,"windowWidth":375,"windowHeight":617,"pixelRatio":2,"screenWidth":375,"screenHeight":667,"language":"zh-CN","statusbarHeight":0,"system":"iOS 11.0","platform":"ios","model":"iPhone","errMsg":"getSystemInfo:ok"}]

uni.getSystemInfoSync() 这个api在main.js调用有问题。其他vue页面可以正常调用

回复 hoey:即使写在main。js里建议在app初始化之后再调用

喜欢技术的前端
uni.getSystemInfo() screenHeight这个参数数值只有不到一半的高度，红米4A上，麻烦看一下

回复 DCloud_UNI_GSQ: uni.getSystemInfo 获取的windowHeight,windowTop高度不正确 {"windowTop":440,"windowBottom":0,"windowWidth":375,"windowHeight":227,"pixelRatio":2,"screenWidth":375,"screenHeight":667,"language":"zh-CN","statusBarHeight":0,"system":"iOS 10.3","platform":"ios","model":"iPhone","safeArea":{"left":0,"right":375,"top":0,"bottom":667,"width":375,"height":667},"safeAreaInsets":{"top":0,"right":0,"bottom":0,"left":0},"errMsg":"getSystemInfo:ok"}
