2. 项目的启动文件介绍

项目的启动文件位于 Signals/Classes/Core/SignalManager.swift。这个文件是整个项目的关键，负责管理和分发信号。

SignalManager.swift

import Foundation

public class SignalManager {
    public static let shared = SignalManager()
    private var signals: [String: Signal] = [:]

    private init() {}

    public func addSignal(_ signal: Signal) {
        signals[signal.name] = signal
    }

    public func removeSignal(_ name: String) {
        signals.removeValue(forKey: name)
    }

    public func signal(_ name: String) -> Signal? {
        return signals[name]
    }
}

功能介绍

• shared: 单例实例。
• signals: 存储所有信号的字典。
• addSignal(_:): 添加信号。
• removeSignal(_:): 移除信号。
• signal(_:): 获取信号。

3. 项目的配置文件介绍

项目的配置文件主要是 Signals.podspec，用于配置 CocoaPods 的相关信息。

Signals.podspec

Pod::Spec.new do |spec|
  spec.name         = "Signals"
  spec.version      = "6.1.0"
  spec.summary      = "Elegant eventing"
  spec.description  = <<-DESC
    Signals is an eventing framework that enables you to implement an observer pattern or a notification center in a type-safe way.
  DESC
  spec.homepage     = "https://github.com/artman/Signals"
  spec.license      = { :type => "MIT", :file => "LICENSE" }
  spec.author       = { "Tuomas Artman" => "[email protected]" }
  spec.social_media_url = "https://twitter.com/artman"
  spec.platform     = :ios, "8.0"
  spec.source       = { :git => "https://github.com/artman/Signals.git", :tag => "#{spec.version}" }
  spec.source_files = "Signals/**/*.{swift}"
  spec.requires_arc = true
end
