该应用程序在iOS 11更新之前正常工作.在iOS 11推出之后,一些用户得到了以下崩溃但我无法在模拟器iOS 11中重现这一点.基于fabric.io,并非所有iOS 11都经历过这种情况,到目前为止我只收到了来自4个用户的22个崩溃报告.需要一些帮助,谢谢.

我最近刚从android迁移到React Native。因此需要一些帮助。为什么我无法访问同一类上的变量，例如，当我从另一个类调用URL_API_SERVER时，却给了我“ Undefined / api / v2”。

class Constant {
    static BASE_URL = 'https://xxxxx';
    static URL_API_SERVER = this.BASE_URL + '/api/v2';
    static STATIC_BASEURL = this.BASE_URL + '/static';
    static URLSTRING_FAQ = this.STATIC_BASEURL + '/FAQ.html';
    static URLSTRING_TOU = this.STATIC_BASEURL + '/TOU.html';
}

export default Constant;
