各种弹出窗口，主要包含Toast，Loading，Alert等HUD，以及各个方向的弹出式窗口。

用法详见demo。

1.在 Podfile 中添加 pod ‘SwiftShow’

2.执行 pod install 或 pod update

3.导入 import SwiftShow

从 Xcode 11 开始，集成了 Swift Package Manager，使用起来非常方便。SwiftShow 也支持通过 Swift Package Manager 集成。

在 Xcode 的菜单栏中选择 File > Swift Packages > Add Pacakage Dependency，然后在搜索栏输入

https://github.com/jackiehu/SwiftShow，即可完成集成

SwiftShow 也支持手动集成，只需把Sources文件夹中的SwiftShow文件夹拖进需要集成的项目即可

基本弹窗API全部都在Show.swift，其中包括多个种类
