Mac配置CocoaPods

Posted on 05/03/202423/09/2024 by XIAO WEN

本文介绍安装并使用CocoaPods

CocosPods的官网: https://www.cocoapods.org/

前言

CocoaPods是一个ruby gem，不知道具体是啥暂时也没关系～

安装CocoaPods的完整流程是：1、安装Homebrew -> 2、安装Ruby –> 3、安装并配置CocoaPods。

三者之间有一个链式的依赖关系：Homebrew 用于安装 Ruby，然后 Ruby 用于运行 CocoaPods。

所以开始之前，我们先要了解两个东西，分别是Homebrew和Ruby。

1、Homebrew

官网：https://brew.sh/

Homebrew 是 Mac 操作系统上的一个包管理器，它可以让我们更方便地安装、更新和删除软件。Homebrew 可以用来安装 Ruby，也可以安装许多其他类型的软件。

安装Homebrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Updated 3 taps (homebrew/services, homebrew/core and homebrew/cask).
==> Installation successful!

==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics
No analytics data has been sent yet (nor will any be during this install run).

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
  https://github.com/Homebrew/brew#donations

==> Next steps:
- Run brew help to get started
- Further documentation:
    https://docs.brew.sh

if there is a Warning like:

 Warning: /opt/homebrew/bin is not in your PATH.
  Instructions on how to configure your shell for Homebrew
  can be found in the 'Next steps' section below.

Steps

Next steps:
- Run these two commands in your terminal to add Homebrew to your PATH:
    (echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/hsiao/.zprofile
    eval "$(/opt/homebrew/bin/brew shellenv)"

we should follow the steps with two command:

1、(echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/hsiao/.zprofile

2、eval "$(/opt/homebrew/bin/brew shellenv)"

2、Ruby

官网：https://www.ruby-lang.org/en/

Ruby 是一种开源的编程语言，它易于理解和编写。CocoaPods 是用 Ruby 编写的一个gem，因此我们需要在计算机上安装 Ruby 才能使用 CocoaPods。

Mac系统自带的 Ruby 版本通常位于/usr/bin/ruby路径下，但自带的通常是较低版本，不建议用它来开发。建议同时安装最新版本的Ruby，并制定使用我们所安装的版本（当前最新版本为3.3.0）的 Ruby 版本进行开发。

我们可以采用rvm来管理多个不同版本的Ruby，就像flutter也可以使用fvm来管理。

By default, binaries installed by gem will be placed into:

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc

For compilers to find ruby you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/ruby/lib"

⚠️注意：要将当前Ruby设置为默认版本，不然在下一步安装CocoaPods会报兼容性错误，因为默认ruby版本太低了

默认版本太低报错

➜  ~

安装过程结束，接下来我们需要初始化pod，这个过程会设置master repo，也就是配置默认的源，但是这个过程也可能异常，稍后会介绍。

初始化pod

pod setup

🤯Oops，发生了一个意外：

zsh:command not found:pod

这个错误通常表示pod命令没有被正确添加到当前的$PATH环境变量中，也就是说，系统找不到pod命令的位置。

我们是通过gem install cocoapods命令安装的 CocoaPods，那么 pod 命令应该位于 Ruby Gems 的bin目录中。但这个目录可能没有被加入到$PATH环境变量中，因此需要手动添加。

依然以 zsh 为例，你需要做的是，打开~/.zshrc文件，然后添加下面这一行：

export PATH="$PATH:$(gem env gemdir)/bin"

或者使用命令行：

echo 'export PATH="$PATH:$(gem env gemdir)/bin"' >> ~/.zshrc
source ~/.zshrc

然后重新打开终端。

查验一下是否已经添加到环境变量中：

cat ~/.zshrc

export PATH="/user/local/bin:$PATH"
export PATH="/opt/homebrew/opt/ruby/bin:$PATH"
export LDFLAGS="-L/opt/homebrew/opt/ruby/lib"
export CPPFLAGS="-I/opt/homebrew/opt/ruby/include"
export PATH="$PATH:$(gem env gemdir)/bin"

包含了export PATH="$PATH:$(gem env gemdir)/bin"就能使用pod指令了。

继续完成初始化工作

pod setup
Setup completed

使用Pod的搜索功能

pod search AFNetworking

搜索遇到问题：

Setup completed
[!]Unable to find a pod with name, author, summary, or description matching 'AFNetworking'

针对该问题，网络上一种

方案A：是认为是search缓存导致的，解决方案：

rm ~/Library/Caches/CocoaPods/search_index.json

但 实测无效🙅。另一种

方案B：是不管当前问题，直接使用Xcode创建一个iOS项目，并使用pod随便引用一个三方库如AFNetworking，最后执行pod install完成之后，再回到这里就能正常使用pod search功能。本文没尝试这种方案。。。

那该怎么解决呢？先看看pod环境

pod env

Logs:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

解决方案是：

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

其实这里补充很关键的一点是，首先，确保已经安装了 Xcode 和 Xcode 命令行工具。如果没有，请在 App Store 中下载并安装 Xcode，并打开终端输入以下命令以安装 Xcode 命令行工具：
xcode-select --install

最后我们再次检查pod环境：pod env，好了，环境已经没有问题了。

  ~ pod env

到这一步，pod环境已经正常，但在此使用pod的搜索功能还是报错找不到对应的库。

我们查看一下本地已添加的私有仓库

pod repo

😧发现竟然一个都没有：

0 repos

这意味着没有本地仓库，那我们可以使用pod repo add命令添加一个私有仓库。例如，执行pod repo add <repo-name> <repo-url>来添加一个私有仓库。

这里添加官方私有仓库

pod repo add cocoapods https://github.com/CocoaPods/Specs.git

Logs

Cloning spec repo `cocoapods` from `https://github.com/CocoaPods/Specs.git`

这个过程需要等待一段时间⏳，指令结束后我们再次查看本地似有仓库，看到已经包含官方私有仓库了：

pod repo

cocoapods
- Type: git (remotes/origin/master)
- URL:  https://github.com/CocoaPods/Specs.git
- Path: /Users/rayvision/.cocoapods/repos/cocoapods

📌也有安装清华大学的私有仓库，但是本文主打一个能够科学上网、所以未采用该方案。

使用清华源：

pod repo add tuna https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git

[清华源]：https://mirrors.tuna.tsinghua.edu.cn/help/CocoaPods/

安装过程终于快收尾了，再来试试搜索功能：

pod search AFNetworking

没想到还是报一样的错误❌，找不到！！！

😊其实到这里重开一遍终端再次执行搜索指令，就能正常工作了。

或者在设置官方私有仓库之后执行：

pod repo update --verbose

《Head First Java》03_primitive主数据类型和引用

Posted on 03/01/202408/01/2024 by XIAO WEN

变量分为primitive主数据类型和引用

声明变量

必须声明所有变量的类型
primitive主数据类型用来保存基本类型的值，包括整数、布尔和浮点数等
对象引用保存的是对象的引用
variables must have a type, variables must have a name.
类型在前，名称在后 int count;

primitive主数据类型（也叫基本数据类型）的大小

类型	位数	值域
boolean	由JVM决定	true / false
char	16 bits	0 ～ 65535

byte	8 bits	-128 ～ 127
short	16 bits	-32768 ～ 32767
int	32 bits	-2147483648 ～ 2147483647
long	64 bits	-很大～ +很大

float	32 bits	范围规模可变
double	64 bits	范围规模可变

基本数据类型类型所占大小及其取值范围

溢位：某个类型不足以装下某个具体值，会丢失精度

变量的命名规则

能包含字母、数字、下划线
但是字母不能在开头

《Head First Java》02_类与对象

Posted on 02/01/202403/01/2024 by XIAO WEN

面向对象具有较强的适应性与可拓展性

面向对象的继承Inheritance

找出相同类的共同部分
将共同部分提取成新的类
将旧类以继承关系连接到新类
子类可以覆盖父类的方法，来实现字类特有的方法
父类比较抽象，字类比较具体

以对象来思考

当设计一个类时，要记得对象是靠类的模型塑造出来的
对象是已知的事物（实例变量instance variable）表示对象的状态，每个独立的对象都会拥有一份该类型的值
对象会执行的动作（方法methods）表示对象的行为

创建对象

编写类
编写测试用的类
在测试用的类中创建对象，并存取对象的变量、调用对象的方法

Java会拾荒（主动管理内存）

创建出来的Java对象会被存储在叫做堆（Heap）的内存中，这个堆最大的特点是支持回收垃圾（Garbage-Collectible Heap），若Java虚拟机察觉到某个对象将不会再被使用时，便会将其标记为“可回收”，当内存开始不足，垃圾收集器便会启动来清理垃圾回收空间，让空间能够再次被利用。

问与答

如何创建全局的变量或方法？

使用public、static和final修饰

全局的函数与数据，是否与面向对象的概念相违背？

什么是Java程序，以及如何提交？

Java类由一组类组成，其中有一个类带有启动用的main()方法，用户需要安装Java虚拟机才能让程序运行。

若有成百上千个类时要如何提交？是否可以包装成类似单一应用程序的形式？

可将所有文件包装进依据pkzip格式来存档的Java Archive（.jar）文件，在该文件中可引入一个叫做manifest的文件、其内部定义jar的哪个文件带有启动程序的main()方法

要点

面向对象设计拓展功能不需要改动之前已经测试好的程序代码
所有的Java程序都定义在类中
类如同蓝图、描述该类型的对象要如何创建
对象自治，你无需在于它如何完成任务
对象有已知的事物，并能执行工作
对象本身已知道的事物称为实例变量，它代表对象的状态
对象可执行的动作称为方法，它代表对象的行为
创建类时，可能同时会需要创建独立、测试用的类
类可以继承自较为抽象的父类
Java的程序在执行期是一组会互相交谈的对象

使用HandyJSON遇到的一个报错

Posted on 02/01/202402/01/2024 by XIAO WEN

根据HandyJSON官方仓库的使用介绍，在swift的枚举类型使用HandyJSON只需要让枚举遵守HandyJSONEnum协议即可。

To be convertable, An enum must conform to HandyJSONEnum protocol. Nothing special need to do now.

官方示例：

enum AnimalType: String, HandyJSONEnum {
    case Cat = "cat"
    case Dog = "dog"
    case Bird = "bird"
}

struct Animal: HandyJSON {
    var name: String?
    var type: AnimalType?
}

let jsonString = "{\"type\":\"cat\",\"name\":\"Tom\"}"
if let animal = Animal.deserialize(from: jsonString) {
    print(animal.type?.rawValue)
}

我的场景是，定义的枚举需要在OC中使用，所以用@objc public修饰了我的枚举，定义如下：

@objc public enum ConnectInteractionType: UInt, HandyJSONEnum {

    /// 未知
    case unknown = 0
    /// 触摸模式
    case touch = 1
    /// 指针模式(默认值)
    case point = 2

    func info() -> ConnectItemInfo {
        switch self {
        case .unknown:
            return ConnectItemInfo(title: "")
        case .touch:
            return ConnectItemInfo(title: "Touch Mode", normalIconName: "icon_interaction_touch")
        case .point:
            return ConnectItemInfo(title: "Pointer Mode", normalIconName: "icon_interaction_point")
        }
    }
}

错误信息：

Thread 1: "-[__SwiftValue unsignedLongLongValue]: unrecognized selector sent to instance 0x28126eca0"

经过排查，只有当我的枚举遵守了该协议，才会产生这个错误，所以确定错误与HandyJSONEnum是有关的。

而且，如果该枚举不使用混编，也就是取消掉@objc public后，也不会出现这个问题，

所以总结一下是：当swift中的枚举需要在oc中混编时，使用HandyJSON解析时，会解析失败。

《Head First Java》01_基本概念

Posted on 01/01/202402/01/2024 by XIAO WEN

Java的特点：

友好的语法、
面向对象、
内存管理、
跨平台可移植性。

目标：write once and run-anywhere.

工作方式：

源代码（.java格式）
编译器编译（javac）
字节码（.class格式）
在jvm上运行（可以将字节码转换成平台能够理解的形式来运行）

比如新建的一个java文件叫做MyFirstApp.java

使用javac编译器指令javac MyFirstApp会将其编译成MyFirstApp.class

最后使用%java MyFirstApp就能运行，但是得确保MyFirstApp.java内部有且仅有一个main函数。

Java的版本：

1.02到1.1都算Java
1.2、1.3、和1.4都叫Java 2
1.5开始叫做Java 5.0
