以太坊智能合约课03-web3.js 基础

Thu, 14 Sep 2023 00:00:00 +0000

开发以太坊区块链应用程序，涉及到以下部分:

智能合约开发 – 使用solidity语言编写代码，部署到区块链。
网站或客户端开发 – 与区块链中的智能合约进行交互，读写数据。
在进行网站或客户端开发时，就需要用到web3.js。web3.js库是一个javascript库，可以让你执行很多与区块链进行交互的任务，例如：

以太币转账
读写智能合约中的数据
创建智能合约

npm install web3

web3.js是一个库集合，允许您使用HTTP、IPC或WebSocket与本地或远程以太坊节点交互。
Web3.js是一个JavaScript API库。要使DApp在以太坊上运行，我们可以使用web3.js库提供的web3对象
Web3.js通过RPC调用与本地节点通信，它可以用于任何暴露了RPC层的以太坊节点
web3包含了eth对象-web3.eth（专门与以太坊区块链交互）和shh对象-web3.shh（用于与Whisper交互，Whisper是以太坊生态一部分，用于消息传递）

连接以太坊节点
要访问以太坊网络，需要连接到Ethereum节点。

有几种方法可以做到这一点，可以使用Geth或Parity运行自己的Ethereum节点。但这需要从区块链下载大量数据并保持同步，很麻烦。

比较方便的方法是，使用Infura访问Ethereum节点。Infura是一个免费提供Ethereum节点的服务。

在Infura上注册账号https://app.infura.io/，创建项目，在项目详情页上可以查看API KEY：使用API KEY，就可以访问以太坊网络节点。


const { Web3 } = require("web3");
const web3 = new Web3(
  new Web3.providers.HttpProvider(
    "https://mainnet.infura.io/v3/1e61012658114abe821130e25a4a8429",
  ),
);

    ],
    name: "balanceOf",
    outputs: [
      {

];

// DAI token contract
const tokenContract = "0x6B175474E89094C44Da98b954EedeAC495271d0F";
// A DAI token holder
const tokenHolder = "0x075e72a5eDf65F0A5f44699c7654C1a76941Ddc8";
const contract = new web3.eth.Contract(balanceOfABI, tokenContract);

async function getTokenBalance() {
  const result = await contract.methods.balanceOf(tokenHolder).call();
  const formattedResult = web3.utils.fromWei(result, "ether");
  console.log(formattedResult);
}

getTokenBalance();

以太坊智能合约课02-hardhat

Thu, 14 Sep 2023 00:00:00 +0000

掌握了 Hardhat 开发框架的基本用法；创建了一个web3项目；编写修改了智能合约；执行了单元测试；启动运行了本地区块链节点；将合约文件成功进行编译和部署；
还安装了 MetaMask 钱包，并连接了本地网络和测试账户进行测试。

https://nodejs.org/en/download/

https://baijiahao.baidu.com/s?id=1727989741134662012&wfr=spider&for=pc

https://hardhat.org/

contract ：声明一个合约；

memory：和 storage 关键字相反，代表了变量只会临时放在内存中，不会存储在合约的状态中；

view：声明该方法为只读方法，不会改变合约本身的状态。

在本地网络上部署合约

npx hardhat node 命令，启动区块链网络一个本地节点


这个命令的意思是，按照 hardhat.config.js 中声明的配置，启动一个本地区块链网络的节点。在每次启动时，默认会提供 20 个钱包账户和私钥，每个钱包提供 10000 个 ETH 做测试。

把合约部署到了本地网络上
npx hardhat run ./scripts/deploy.js --network localhost

到这步为止，我们的 Greeter 合约就成功在本地网络上部署好了，也成功使用 MetaMask 钱包，进行了本地网络连接、测试账户导入。

这个命令用于执行单元测试
npx hardhat test

      ✔ Should set the right owner
      ✔ Should receive and store the funds to lock
      ✔ Should fail if the unlockTime is not in the future
    Withdrawals
      Validations
        ✔ Should revert with the right error if called too soon
        ✔ Should revert with the right error if called from another account
        ✔ Shouldn't fail if the unlockTime has arrived and the owner calls it
      Events
        ✔ Should emit an event on withdrawals
      Transfers
        ✔ Should transfer the funds to the owner


  9 passing (962ms)


启动一个控制台程序，方便交互式输入输出
npx hardhat console

这个命令的作用就是编译
npx hardhat compile

把编译出来的文件清理一下。
npx hardhat clean

IELTS Speaking Robots

Fri, 08 Sep 2023 00:00:00 +0000

雅思口语 Robots

IELTS Speaking Robots  

Part 1

Question 1

Are robots important ?

Robots have always been important in the development of technology,
 and they will continue to be so in the future. Robots can help us complete tasks 
that are difficult or dangerous for humans, such as exploring space or working in environments 
that are harmful to human health. In addition, robots can also help us improve our productivity 
and efficiency in many fields, such as manufacturing, logistics, and agriculture. 
Therefore, I think robots are very important for our society and will continue to be so in the future.

Question 2

What are the uses of robots ?

Robots are used in many different fields. For example, they can be used in manufacturing
 to assemble and inspect products. They can also be used in healthcare to assist doctors and nurses 
in surgery and patient care. In addition, robots are also used in the military to perform missions 
that are too dangerous for humans. In general, robots have become an integral part of our society 
and will continue to expand their applications in the future.

Question 3

What are the differences between domestic robots and industrial robots ?

Domestic robots and industrial robots have some differences in their applications and functions. Domestic robots are mainly used to perform household tasks such as cleaning, cooking, and taking care of the elderly and children. They can help us simplify our daily lives and improve our quality of life. On the other hand, industrial robots are mainly used to perform repetitive and precision tasks in factories and workshops. They can help us improve productivity and efficiency in manufacturing and logistics. Therefore, the main differences between domestic robots and industrial robots are their applications and functions, but both can contribute to the development of society.

Question 4

Would robots affect people’s lives ?

Robots can indeed affect people's lives. On the one hand, robots can help us complete tasks 
that are difficult or dangerous for humans, such as exploring space or working in environments 
that are harmful to human health. In addition, robots can also help us improve our productivity 
and efficiency in many fields, such as manufacturing, logistics, and agriculture. Therefore, 
robots can help us improve our lives and work conditions. On the other hand, robots may also create 
some employment problems, because robots can replace some human work, resulting in the loss of 
some jobs. Therefore, we need to take a positive attitude to the development of technology, 
while also facing the impact on employment and other problems caused by it.

Question 5

Have you ever watched a movie about robots ?

Yes, I have watched many movies about robots. Some of them are "Terminator", "Transformers", 
"A.I. Artificial Intelligence", and many more. These movies show how robots can help us solve problems 
and save the world, but also how they can be dangerous and create conflicts.
 It's really interesting to see how movie creators imagine the future and the role of robots in our society.

Question 6

Should we let a robot drive for us for  a long journeys?

For a long journey, I think we should not rely too much on robots to drive for us. 
Although robots can drive very well, they may not be able to react as quickly as humans 
in complex and changing environments. In addition, if the robot fails during the journey, 
it may pose a great threat to the safety of the passengers. Therefore, I think we should 
let a robot drive for us for a long journeys after assessing the risks and ensuring the safety of the passengers.

Question 7

What can robots do for you at home ?

Robots can do many things for me at home. They can help me clean the house, cook, wash clothes, 
and so on. In addition, some robots can also be used to monitor the home environment, 
such as monitoring the temperature and humidity, and detecting whether there is a fire or a leak. 
These robots can help us detect problems and take appropriate action as soon as possible, 
ensuring the safety of the home. In short, robots can help us improve our quality of life and ensure our safety at home.

Tea is a traditional Chinese beverage, so it's something I often have with meals 
or as a late afternoon treat. As for coffee, I usually have it first thing in the morning 
or when I'm feeling a bit tired during the day.


Question 4

Do you prefer to use tea or coffee to serve your guests ?

"Personally, I prefer to serve tea to my guests because I think tea has a more relaxing 
and enjoyable atmosphere than coffee. Tea has a unique aroma and taste that 
can help people relax and unwind. Also, tea is considered a traditional beverage in many cultures, 
so it can also add a sense of hospitality and cultural value to the experience of serving guests. 
However, I am also aware that coffee is also a popular beverage, 
so I would consider serving coffee to guests if they prefer it or ask for it."

Question 5

When was the last time you had a cup of coffee or tea ?

The last time I had coffee was yesterday afternoon. I was feeling a little tired 
and needed to wake myself up, so I brewed a cup of coffee and sat down to read a book. The book was very interesting and I couldn't put it down, so I kept drinking the coffee and reading until it was dark outside. 
The coffee helped me feel more awake and I was able to concentrate better on my reading.

Question 6

Do you usually buy your coffee in a coffee shop ?

I do not usually buy coffee in a coffee shop. Instead, I usually make coffee at home 
using a coffee maker. However, sometimes I go to a coffee shop to buy coffee 
when I am out and about or when I want to treat myself to a special cup of coffee. 
In the coffee shop, I like to enjoy the atmosphere and watch people go 
by while sipping my coffee. It's a great way to relax and unwind.

 the rumble of airplanes passing overhead, or the constant hum of construction sites, 
noise pollution is a real problem in many parts of the world.
This noise not only affects our health and well-being but can also impact our productivity and efficiency.

IELTS Speaking Test Transport

Sun, 03 Sep 2023 00:00:00 +0000

雅思口语 Transport

Question 1

How do you go to work or go to school?

I usually take the subway to work or school in Beijing. There are many convenient subway lines in Beijing, and I can go to most places within an hour. The subway is also a more environmentally friendly way to travel compared to driving or taking a taxi. Plus, I can read or relax on the subway without being stuck in traffic jams.

Question 2

What’s the most popular means of transportation in your hometown ?

In Beijing, the most popular means of transportation is the subway. Beijing has a large network of subway lines that cover most parts of the city. The subway is fast, convenient, and relatively inexpensive, making it a popular choice for many people. In addition, the subway is also a more environmentally friendly mode of transportation compared to driving or taking a taxi.

Question 3

How far is it from  your home to work or to school ?

It's about 8 kilometers from my home to work, and it takes about 30 minutes to get to work on the subway. As for the distance from my home to school, it's about 10 kilometers, and I usually cycle to school because it's not far and also good for my health.

Question 4

Do you think people will drive more in the future ?

It's hard to say whether people will drive more in the future, as it depends on many factors such as the development of technology, the improvement of public transportation, and the change of people's travel habits.
Personally, I think that as the traffic congestion and air pollution in cities become increasingly serious, more people may choose to use public transportation or other environmentally friendly modes of transportation, such as cycling or walking. At the same time, with the development of technology, electric vehicles may also become more popular in the future, reducing the demand for traditional gasoline-powered vehicles.
However, if the infrastructure and management of public transportation cannot keep up with the demand, people may still choose to drive. In addition, the rise of self-driving technology may also affect people's travel methods. If self-driving technology becomes more mature and widely used, it may indeed increase the number of people who drive.
In short, the future trend of people's travel methods is difficult to predict, but it will be affected by many factors. We can only hope that more environmentally friendly modes of transportation will become more popular in the future.

个人对AR增强现实能做什么用途的理解层次

第1个层次

超感官体验：拿一个真实凳子坐下来，手机环顾凳子的四周，发现坐在虚拟的沙发或浴缸中。

使用摄像头的场景都可以用AR：扫一扫二维码可以打开商品网页和电子支付，于是用户愿意在APP中打开摄像头权限。AR也需要打开摄像头权限，但因为扫一扫二维码先让用户允许了摄像头权限，所以AR就不需要重复请求权限了。

在线下的真实产品上，展示线上的产品信息：在超市看到产品，会拿手机上网查产品信息和网友评价。在网站看到产品，要去实体店看一看实际产品。AR将线上和线下信息叠加在一起，顾客减少了信息搜索时间，而商家能将广告直接传递给顾客。

第2个层次

一种新颖的内容呈现方式：互联网诞生以来，人们用文字、声音、图像、视频、动画、3D等传递和表达内容。虽然AR显示的内容还是图像、视频、3D，但是交互方式变化了。老人们不习惯使用菜单繁多的智能手机打电话，愿意用老式电话或功能机，因为操作简单。老人们不习惯使用手机地图，愿意用纸质的大地图，因为不用学习地图APP，也不用忍受地图APP必须按它的方式用。

一种节约时间的方式：组装晒衣架是一件费时间的事，各个连接管零散地摆在地上，有的管子是要横着的，有的管子是要竖着的，管子之间有安装顺序。人们重复地看说明书，分辨每个管子的形状，为了能顺利安装。AR将完整的晒衣架、各个管子的数字序号、摆放的位置等信息呈现在人们眼前，人们不用看说明书就能快速地安装晒衣架。

一种结合人工智能的方式：人工智能检测人脸姿态、人体姿态、目标物体是什么和在哪里，AR用生动的内容将人工智能的信息表现出来。

一种单人和多人游戏的方式：小孩没有玩具时，会把房间中的东西想象成游戏道具。两个人缺少游戏道具时，会拿特征明显的东西充当缺少的道具。AR让人们不用像做梦一样想象道具，让人们看到想象的道具。

第3个层次

AR通过信息、数据、资讯等叠加在真实物体上，让真实物体增强了内容，带给了用户价值。

关键词：真实物体、叠加的信息、带给用户的价值。

什么样的叠加信息，能带给用户价值？

第1种：用户不知道的和没有掌握的知识，却要操作真实物体。对用户有学习价值。

第2种：用户熟悉操作真实物体的流程，却无法记忆仪器数据、检测数据。对用户有工作价值。

第3种：用户需要在特定地方联想的事物，有感情的需求。对用户有情感价值。

第4种：用户需要对真实物体标注或假想，有游戏的需求。对用户有工具价值。

第4个层次

判断AR应用是否有价值和如何改进AR应用。

情感价值：

人物上显示AR装饰：拍照美化。

贺卡上显示AR：在视觉上附加了听觉内容。

玩具上显示AR：让玩具变得像有生命。

AR 360度全景：宅在房间中体验旅游景点。

AR美甲、AR美妆、AR宠物等。

工具价值：

AR玩具枪：让玩具枪变成游戏中的道具。

AR汽车抬头显示器、AR房屋平面图、AR密室逃脱游戏、AR模拟农场等。

学习价值：

AR绘画：将投影在白纸上的图案描一遍。

AR音乐演奏：在乐器上显示按键和乐谱。

工作价值：

AR远程协助：节约师傅亲临现场指导的开销成本。

帮助 WKWebView 管理 cookie

帮助 WKWebView 管理 cookie

https://github.com/GaoGuohao/GGWkCookie

WKWebView管理cookie是很麻烦事，经常出现 App自定义cookie的值丢失 或 更新不及时 的情况。 通过长期踩坑，总结出WKWebview管理cookie的一种方案。

原理： WKWebview支持的插入脚本的方式，在每次页面渲染前，通过插入的Js脚本检测Cookie是否存在，如不存在，将cookie重新种入的思路。

注意：因为考虑避免子域名和根域名cookie重复出现，该方法所有的Cookie值将种在 根域名上。

将 Flutter 集成到现有应用

Fri, 27 May 2022 00:00:00 +0000

将 Flutter 集成到现有应用

https://juejin.cn/post/7090484738774794271

集成到 iOS 应用

* 在 Xcode 的 Build Phase 以及 CocoaPods 中，添加一个自动构建并引入 Flutter 模块的 Flutter SDK 钩子。
* 将 Flutter 模块构建为通用的 iOS Framework 以便集成到您自己的构建系统中；
* FlutterEngine API 用于启动并持续地为挂载 FlutterViewController 以提供独立的 Flutter 环境；
* 支持了 Objective-C 和 Swift 为宿主的应用程序；
* Flutter 模块可以通过使用 Flutter plugins 与平台进行交互；
* 支持通过从 IDE 或命令行中使用 flutter attach 来实现 Flutter 调试与有状态的热重载。
查看 add-to-app GitHub 示例仓库 中在 iOS 和 Android 平台上引入 Flutter module 的示例项目。
Flutter 可以以 framework 框架的形式添加到你的既有 iOS 应用中。
请参阅 add_to_app 代码示例 的 iOS 目录。

https://github.com/alibaba/flutter_boost/blob/master/example_new_for_ios/lib/main.dart

新一代Flutter-Native混合解决方案。 FlutterBoost是一个Flutter插件，它可以轻松地为现有原生应用程序提供Flutter混合集成方案。FlutterBoost的理念是将Flutter像Webview那样来使用。在现有应用程序中同时管理Native页面和Flutter页面并非易事。 FlutterBoost帮你处理页面的映射和跳转，你只需关心页面的名字和参数即可（通常可以是URL）。

Flutter 模块可以通过使用 Flutter plugins 与平台进行交互

很多时候我们需要监听路由堆栈的变化，这样可以自定义路由堆栈、方便分析异常日志等。

一套高性能渲染引擎来绘制UI，这个引擎就是大名鼎鼎的Skia，Skia是一个2D绘图引擎库

Flutter容器做成浏览器的感觉。填写一个页面地址，然后由容器去管理页面的绘制。在Native侧我们只需要关心如果初始化容器，然后设置容器对应的页面标志即可。

1、修改退出账号功能
2、完善Flutter和原生混编，处理路由映射和跳转，在Native侧我们只需要关心如果初始化容器 , 外层调用方只需关心页面的名字和参数，方便集成不同的模块。
3、Flutter页面全局生命周期监听

Flutter的布局原理
https://juejin.cn/post/6914155427651387399

1、Widget大概可以分为三类组合类、代理类、绘制类
2、所有我们在屏幕上看到的UI最终几乎都会通过RenderObjectWidget实现。而RenderObjectWidget中有个createRenderObject()方法生成RenderObject对象，RenderObject实际负责实际的layout()和paint()。
3、Container组件其实只是一个组合类的控件，在其中封装了多个负责绘制的原子组件。
4、layout() 职能主要是计算控件自身的尺寸和位置偏移
5、整个布局过程就是向下约束 向上传值的过程
6、盒约束中有两种：
* tight（紧约束）：当max和min值相等时，这时传递给子类的是一个确定的宽高值。
* loose（松约束）：当max和min不相等的时候，这种时候对子类的约束是一个范围,称为松约束

AR应用

Fri, 18 Mar 2022 00:00:00 +0000

AR应用

试想一下，如果幻想与现实之间没有了界限，那将会怎样？有了增强现实，这种体验将不仅仅是一种可能，而是真真切切地就在你眼前。
增强现实的绝妙之处，在于能将原本不切实际或天马行空的想法呈现在你眼前，令你的工作、学习、玩乐、购物，以及与周围世界的联系，都随之发生蜕变。
Apple 拥有广阔的增强现实平台，支持增强现实的设备数以亿计，App Store 更提供上千款增强现实类 app。由于 Apple 的硬件和软件均为增强现实度身设计，用来体验增强现实当然再理想不过。
从硬件到软件，都为增强现实打造。
Apple 的硬件和软件经过协同设计，带来了出色的增强现实体验。先进的摄像头、绚丽的显示屏、运动传感器、性能强大的图形处理器，再加上基于用户使用习惯的机器学习技术，和前沿的开发者工具，让这种体验栩栩如生、引人入胜。而且，对增强现实的支持内置于 iOS 和 iPadOS 系统中，因此除了通过增强现实类 app 之外，你还能在 Safari 浏览器、邮件、信息和文件等 app 中，直接通过 AR 快速查看功能来体验。
开发者们正利用增强现实的强大功能，源源不断开发出新的 app。许多常用的 app 中也新加入了增强现实功能。
例如

得物App，AR试鞋功能，AR会识别脚并且适应脚的各种角度，即可通过AR查看试穿鞋的效果。

IKEA Place App。有了 IKEA Place，家居产品的外观、感觉，以及摆放在家中的效果都可以呈现在你眼前，足不出户轻松搞定。借助激光雷达扫描仪1，智能建议会向你推荐适合现有家具和空间的产品，帮你轻松布置房间

可立拍 App。 “AR 空间”提供多种好玩又真实的特效，为你的现实世界增添乐趣。利用激光雷达扫描仪对所在之处进行深度感测之后1，“AR 空间”能在你的房间抛撒漫天彩屑，把地板变成虚拟舞池，或在你身后留下璀璨星光。你可以拍下一段有趣的话、一个精彩的场面，或是随手拍个视频，横屏竖屏都可以，分分钟发布到社交媒体，请大家来围观你崭新的增强现实世界。

现在AR 展示3d模型、可以在任意的平面放置模型，用户可以360度无死角的观察模型的细节。
或者比如让用户看到模型组装的过程，比如坦克的组装过程，组装起来再跑起来这种效果。
另外比如我们可以让模型动起来，同时配一些3d的音效。
在模型的零件上增加一些3d的文字、进行标注。

再就是跟人结合起来，人脸贴图、人脸表情、微笑检测等。

AR口红试妆 人的嘴唇AR上色

AR 试鞋 得物 

AR种菜

AR家具 宜家

多用户AR体验 保龄球 多人游戏

可立拍。

4.3 将3D固定在手指上
4.4 将3D固定在目标物体上
4.5 手部骨骼跟踪
4.6 人体骨骼跟踪
4.7 眼球跟踪

1. 激光雷达扫描功能适用于 iPhone 12 Pro Max、iPhone 13 Pro、iPhone 13 Pro Max、12.9 英寸 iPad Pro (第四代及后续机型) 和 11 英寸 iPad Pro (第二代及后续机型)。
2. 增强现实需要使用配备 iOS 11 和 A9 处理器或更高版本的 iOS 或 iPadOS 设备。

Seed Shop示例应用程序为园丁提供了成熟植物的预览。在苗圃，种子商店从种子包上的轻 App 代码识别植物，并以 3D 显示成年植物。例如，在AR的帮助下，买家可以通过大规模检查虚拟植物相对于相机馈送中的真实物体来查看典型猛犸向日葵的真实高度。

解决WebView 加载慢

Sat, 20 Nov 2021 00:00:00 +0000

一个加载网页的过程中，native、网络、后端处理、CPU都会参与，各自都有必要的工作和依赖关系；让他们相互并行处理而不是相互阻塞才可以让网页加载更快：
* WebView初始化慢，可以在初始化同时先请求数据，让后端和网络不要闲着。
* 
* 后端处理慢，可以让服务器分trunk输出，在后端计算的同时前端也加载网络静态资源。
* 
* 脚本执行慢，就让脚本在最后运行，不阻塞页面解析。
* 
* 同时，合理的预加载、预缓存可以让加载速度的瓶颈更小。
* 
* WebView初始化慢，就随时初始化好一个WebView待用。
* 
* DNS和链接慢，想办法复用客户端使用的域名和链接。
* 
* 脚本执行慢，可以把框架代码拆分出来，在请求页面之前就执行好。

ios应用内购买

Mon, 08 Nov 2021 00:00:00 +0000

用户向苹果服务器发起购买请求，收到购买完成的回调（购买完成后会把钱打给申请内购的银行卡内） 购买成功流程结束后, 向服务器发起验证凭证（app端自己也可以不依靠服务器自行验证） 自己的服务器工作分 4 步：
* 1、接收 iOS 端发过来的购买凭证。
* 2、判断凭证是否已经存在或验证过，然后存储该凭证。
* 3、将该凭证发送到苹果的服务器（区分沙盒环境还是正式环境）验证，并将验证结果返回给客户端。 sandbox 开发环境：https://sandbox.itunes.apple.com/verifyReceipt prod 生产环境：https://buy.itunes.apple.com/verifyReceipt
* 4、修改用户相应的会员权限或发放虚拟物品。
简单来说就是将该购买凭证用 Base64 编码，然后 POST 给苹果的验证服务器，苹果将验证结果以 JSON 形式返回。



对于自动续订订阅，我们自己的服务器完全可以与apple server的交互应对用户的订阅状态，只需要确定客户端传来的用户第一次购买， user id 对应 original-transaction-id的关系。后面的续订，取消，变更套餐，完全不依赖于客户端传来的信息。


For auto-renewable subscriptions, the App Store can also notify your server of key subscription events.


Understand Product Types
There are four In-App Purchase types you can offer:
* Consumables are a type that are depleted after one use. Customers can purchase them multiple times. 
* Non-consumables are a type that customers purchase once. They don't expire. 
* Auto-renewable subscriptions to services or content are a type that customers purchase once and that renew automatically on a recurring basis until customers decide to cancel. 
* Non-renewing subscriptions to services or content provide access over a limited duration and don't renew automatically. Customers can purchase them again.

消耗型、非消耗型、自动续期订阅和非续期订阅。

深入探索AR增强现实的精彩世界

Sun, 07 Nov 2021 00:00:00 +0000

# 深入探索增强现实的精彩世界。

在世界领先的增强现实平台 — iOS 和 iPadOS 之上，为数亿用户创造无可比拟的逼真增强现实体验。借助 ARKit 和 RealityKit 等功能强大的框架以及 Reality Composer 和 Reality Converter等创意工具，要在增强现实中生动呈现各种奇思妙想变得前所未有的简单。

# ARKit5

## 利用 ARKit 5 探索更广阔奇妙的世界

ARKit 5 新增了伦敦及更多美国城市对位置锚定功能的支持，让您能够为特定地点创建增强现实体验，如伦敦眼和时代广场，甚至是您家附近。ARKit 5 还增强了运动追踪功能，并为 iPad Pro (第五代) 上的超广角摄像头提供面部追踪支持。借助新的“轻 App 码”锚定，您可以将来自轻 App 或 ARKit app 的虚拟内容植入到印刷或数字材料内的轻 App 码中。

### 扩展了面部追踪支持范围

在配备 A12 仿生芯片及更新版本芯片的设备上 (包括 iPhone SE)，面部追踪支持现已扩展至前置摄像头，让更多用户能通过前置摄像头体验到增强现实的乐趣。最新 iPad Pro (第五代) 上的超广角摄像头也支持面部追踪。使用原深感摄像头能一次追踪最多三个面孔，让拟我表情和 Snapchat 等前置摄像头体验更有趣。

### 位置锚定

在特定的地点 (例如城市和著名地标) 放置增强现实体验。位置锚定让您能够将增强现实作品固定到特定的经纬度和海拔高度。用户可以绕着虚拟物体移动，从不同的角度观察它们，就像通过相机镜头观察现实物体一样。

### 景深 API

激光雷达扫描仪中内置了先进的场景理解功能，以助此 API 使用关于周围环境的逐像素深度信息。通过将这种深度信息与由场景几何结构感测生成的 3D 网格数据相结合，您能在 app 中即时放置虚拟物体，并将它们无缝地融入到现实环境中，让虚拟物体的遮挡显得更加真实。这将有助于您在 app 中推出相关新功能，比如进行更精确的测量，或对用户的环境应用某些效果。

### 场景几何结构感测

借助此功能，您可为您的空间创建拓扑图，并使用标签来标识地板、墙壁、天花板、窗户、门和座椅。这种对现实世界的深度理解能帮助您为虚拟对象实现物体遮挡的功能和现实世界的物理特效，同时为您提供更多的信息来支持增强现实工作流程。

### 即时增强现实

激光雷达扫描仪能够实现超快的平面检测 — 无需扫描，便可在现实世界中即时放置增强现实物品。在 iPhone 12 Pro、iPhone 12 Pro Max 和 iPad Pro 上，您无需更改任何代码，所有使用 ARKit 构建的 app 会自动支持即时增强现实物品放置功能。 

### 人物遮挡

增强现实内容能够以逼真的方式从现实世界中的人物前后通过，带来更身临其境的增强现实体验，同时能在几乎任何环境中实现绿屏风格效果。在 iPhone 12、iPhone 12 Pro 和 iPad Pro 上，您无需更改任何代码，所有使用 ARKit 构建的 app 中的深度估计功能都会得到优化。

### 动作捕捉

用单个摄像头实时捕捉人物的动作。将身体姿态和动作化为一系列关节及骨骼活动，让您能在增强现实体验中输入运动和姿势，让人物成为增强现实体验的焦点。在 iPhone 12、iPhone 12 Pro 和 iPad Pro上，您无需更改任何代码，所有使用 ARKit 构建的 app 中的高度估计功能都会得到优化。

### 同时使用前置和后置摄像头

您可以同时使用前置和后置摄像头来进行面部和现实场景追踪，开创更多新的可能。例如，用户可以仅使用自己的面部与后置摄像头视图中的增强现实内容进行交互。

### 其他功能改进

一次检测最多 100 张图像，并自动估计图像中对象的实际尺寸。3D 对象检测功能变得更强大，并能在复杂的环境中更好地识别对象。现在，使用机器学习技术可以更快地检测环境中的平面。

# RealityKit2

RealityKit 框架专门为增强现实量身定制，能够提供逼真的图像渲染、相机特效、动画、物理特效等等。借助原生的 Swift API、ARKit 整合、基于物理的超逼真渲染、变换和骨骼动画、空间音频和刚体物理，RealityKit 让您可以比以往更加快速轻松地进行增强现实开发。

### 物体捕捉

利用 macOS 上新发布的物体捕捉 API，在几分钟内* 即可将 iPhone 或 iPad 中的照片转换专为增强现实而优化的 3D 模型，实现逼真效果。物体捕捉功能使用摄影测量技术将 iPhone 或 iPad 上拍摄的一系列照片转换为 3D 模型，这些模型可以立即在“AR 快速查看”中查看，或整合到您的 Xcode 项目中。

### 自定着色器

RealityKit 使用基于真实物理特性的材质、环境反射、地面阴影、相机噪点、运动模糊等等，让虚拟内容与现实世界完美融合，与真实内容别无二致。RealityKit 2 让您能够利用自定渲染目标和材质更好地控制渲染管线，从而精细地调节增强现实物体和场景的外观与质感。

### 动态素材资源

支持自定载入素材资源，更加灵活地量身定制基于 RealityKit 的体验 — 例如，以编程方式更改每一帧的图像或网格。

### 自定系统

打造自己的实体组件系统，在增强现实场景中组织整理素材资源，在系统层中构建更加复杂的功能。

### 角色控制器

使用这个强大的 Swift API 轻松创建由玩家控制的角色，让用户能够跳转、缩放和探索您创建的增强现实世界和基于 RealityKit 的游戏。

### 物体遮挡

将激光雷达扫描仪提供的信息与 RealityKit 中的边缘检测功能配合使用，让虚拟物体按照您的预期与现实环境进行交互。虚拟物体可以被放置在桌子下、墙壁后或角落处，您将只能看到虚拟物体的正常可见部分，且现实与虚拟物体之间交界的地方也会非常清晰。

### 可调节性能

配合最新 Metal 功能来发挥 GPU 的最大功效，RealityKit 能充分利用 CPU 缓存和多个内核来提供极其流畅的视觉效果和物理模拟效果。您只需要构建一个增强现实体验，它就能够根据每台 iPhone 或 iPad 来自动调节增强现实体验的性能表现。

### 视频纹理

现在，您可以将视频纹理添加到 RealityKit 中场景的任意部分。添加丰富的视频来让虚拟电视屏幕播放电影，或是让虚拟人物微笑，从而让物体、表面甚至人物变得更加生动鲜活。

### 共享的增强现实体验

RealityKit 能够帮助处理联网方面的复杂工作 (例如保持一致的状态、优化网络流量、处理数据包丢失或执行所有权转移)，从而大大简化了构建共享增强现实体验的工作。

### Swift API

RealityKit 简单易用，功能强大，它使用 Swift 丰富的语言特性自动提供完整的功能集，让您能够更快速地构建增强现实体验，而无需样板代码。

# Reality Composer

Reality Composer 是一款功能强大的工具，让您无需具有 3D 经验，即可轻松打造交互式增强现实体验。Reality Converter 能够快速地将现有的 3D 模型转换为 USDZ，这样它就可以在我们的工具以及所有支持增强现实功能的 iPhone 和 iPad 设备上流畅地工作。

借助适用于 iOS、iPadOS 和 macOS 的 Reality Composer，您可以轻松地为 iPhone 或 iPad 构建、测试、调整和模拟增强现实体验。通过实时链接功能，您可以在 Mac 与 iPhone 之间或 Mac 与 iPad 之间快速切换，打造精彩逼真的增强现实体验，然后导出至 AR 快速查看，或使用 Xcode 整合到您的 app 中。

### 内置增强现实资源库

导入您自己的 USDZ 文件，或者利用内置增强现实资源库中数百个现成的虚拟对象。这个资源库能够利用程序化内容生成技术来生成各种素材资源，帮助您自定虚拟对象的大小、样式等。

### 动画和音频

添加可让您移动、缩放的动画，以及向虚拟对象添加“晃动”或“旋转”等强调效果。您可以选择当用户轻点对象、靠近对象或激活某个其他触发器时要发生的操作。您还可以利用空间音频让您的增强现实场景更贴近现实。

### 一体化工具

Xcode 中随附的 Reality Composer 同时也是一个 iOS 和 iPadOS app，让您在 iPhone 或 iPad 上，就能完全构建、测试、调节和模拟增强现实体验。通过实时链接功能，您可以在各个平台之间快速切换，在最适合自己的设备上创造令人惊艳的复杂增强现实体验。

### 录制和播放

借助适用于 iOS 的 Reality Composer，您可以在发生增强现实体验的位置录下传感器和摄像头数据，然后在构建您的 app 时在 iOS 设备上重放。

### 导出至 USDZ

Reality Composer 现在支持导出至 USDZ，而 USDZ 支持在 Reality Composer 中创作的所有动画、锚点和空间音频。

# Reality Converter

全新的 Reality Converter app 让您可以在 Mac 上轻松转换、查看和自定 USDZ 3D 对象。只需拖放常用格式 (如 .obj、.gltf 和 .usd) 的 3D 文件，即可查看转换后的 USDZ 结果，使用自己的纹理来自定材质属性，以及编辑文件元数据。您甚至可以利用内置的 IBL 选项在多种光照条件和环境中预览 USDZ 对象。

全新的 Reality Converter app 让您可以在 Mac 上轻松转换、查看和自定 USDZ 3D 对象。

### USDZ 工具

下载用于生成、验证和检查 USDZ 文件的基于 Python 的基本工具。其中还包括一个用于从其他 3D 文件格式创建 USDZ 的转换器，以及 Pixar 的 USD 库和示例脚本。

#  AR 快速查看

在 iPhone 和 iPad 上，Safari 浏览器、“信息”、“邮件”、“新闻”和“备忘录”等内建 app 使用“快速查看”来显示 3D 或增强现实虚拟对象的 USDZ 文件。您可以在 app 和网站中嵌入“快速查看”视图，让用户可以在现实世界场景中看到细节极其丰富的对象渲染效果，同时支持音频播放。

[AAE10007]错误统计没有数据

问题

错误统计没有数据？
错误分析无数据
错误分析异常
解决方法

错误信息默认下次启动发送。
如出现异常请按照以下顺序排查 ：

1、排查是否有错误日志上报：​启动应用-手动crash-关闭应用-重新启动应用-打印log日志，观察log是否有errors字段。

如果自定义事件集成正确是可以看到这个字段的，iOS用户不需要等待40s（iOS不要在Xcode中点击stop，请使用home键）后重新启动应用，查看log中是否有errors字段；

2.检查是否关闭crash统计，关闭crash统计则后台无法正常展示错误信息。错误统计默认开启状态[MobClick setCrashReportEnabled:YES];

3.是否有集成其他第三方错误统计SDK，或自己获取错误信息的方法，如有此情况，则U-App无法统计到错误信息。

iOS的Library/Cache目录内容会被删除

Thu, 01 Aug 2019 00:00:00 +0000

网上搜索基本的都是说这个目录的内容不会被删除，只是不会被icloud备份而已。
之前的同事将下载的文件放到了Library/Cache目录，之前只是觉得有点奇怪，也没太在意，于是我就背锅了。生产环境偶尔出现用户数据全丢的情况，发现是数据被删除了。再查一下官方文档：
