According to the people's daily of China, the flight control team of the chang'e-5 mission has successfully carried out the separation of the lander and the ascent combination of the chang'e-5 probe with the orbiter and reentry vehicle as planned.

At 4:40 am today, under the precise control of scientific and technological personnel, the chang'e-5 probe assembly was successfully separated.

It is reported that the systems of chang'e-5 probe are in good condition, and the ground TT & C communication is normal. The orbiter and the reentrant combination will continue to fly in the lunar orbit with an average height of about 200 km and wait for the rendezvous and docking of the ascender. The lander and the ascent combination will select an aircraft to implement the lunar soft landing and carry out the follow-up work such as automatic sampling.

The landing site will be a storm ocean in the northwest of the moon. Storm ocean is the largest moon sea on the moon, where human probes have never been before. The storm ocean is a younger region with an age of 3.2 billion to 4 billion years, compared with the quiet sea and the rich sea where human beings have obtained lunar samples.

According to the official news of Beidouxingtong, the subsidiary companies of Beidouxingtong and Xinxingtong have officially released the latest generation of full-system full-frequency centimeter-level high-precision GNSS chips-Hexin Nebulas IV.

According to reports, this chip represents the highest level of domestic satellite navigation chips, has groundbreaking significance in the field of centimeter-level high-precision positioning, and has a leading advantage in the world. While the Nebulas IV chip is iteratively evolving to 22nm, it is the first to realize the integration of baseband + radio frequency + high-precision algorithm on a single chip, supports on-chip RTK, meets the requirements of vehicle regulations, and has better performance, size, and power consumption. The previous generation of chips made breakthroughs to meet the needs of popular applications and better meet the needs of high-end applications such as smart driving and drones.

Various applications based on Beidou will go global with the opening of Beidou system global services. Nebulas IV supports all satellite navigation systems and frequencies in the world, including the latest Beidou III B1C, B2a, and B2b, which will provide a better positioning experience for the broader international market.

背景

pod install 相关类库，尤其update的时候 默认的github太慢了。部分博客指出的清华镜像现在也用不了了，后来发现官方的cdn的确比较好用。

使用步骤

1.podfile添加cdn source删除原来的github Spec

• source 'https://github.com/CocoaPods/Specs.git'
• source 'https://cdn.cocoapods.org/'

前提是pod版本1.8+，查看pod 版本，pod --version

2.大胆删除原来的CocoaPods 分支

pod repo remove master
或手动删除，目录是在 /用户/XXX/.cocoapods/repos/,此目录超级大，删除cocoapods目录即可。

3.执行pod install

pod install 可以看出从cdn安装类库。如果是新项目使用，需要pod setup再使用

背景

ios12月份前需使用WkWebview才能更新app，否则不予上架，所以之前的cordova版本需要升级。

调整步骤：
1.安装插件
cordova plugin add cordova-plugin-wkwebview-file-xhr
参考链接：
https://www.npmjs.com/package/cordova-plugin-wkwebview-file-xhr
2.搜索cordova关键字createConfigurationFromSettings添加下方代码
Cordova6.0后，WK插件就被移除了，兼容到Cordova内部中，所以我在升级后的Cordva中搜索createConfigurationFromSettings 方法，在其内部增加代码

//在return上面添加下面两行代码
      [configuration.preferences setValue:@YES forKey:@"allowFileAccessFromFileURLs"];
      [configuration setValue:@YES forKey:@"_allowUniversalAccessFromFileURLs"];
      return configuration;

3.避免走的坑
白名单默认都安装了，不需要卸载重新安装。以下配置不需要添加到config.xml中。当然视版本不同，可能会有不同的情况，大家根据需要配置调整。

<allow-navigation href="*" />

<preference name="scheme" value="app" />
<preference name="hostname" value="localhost" />

<feature name="CDVWKWebViewEngine">
<param name="ios-package" value="CDVWKWebViewEngine" />
</feature>
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />
