背景： 应用开发总是会涉及到多个环境之间的切换，难道要打不同的域名包，还得给应用改个名字：开发包，测试包，正式包。 这样做，是否太浪费时间了，打包不需要时间吗？这种磨人的操作有没有一劳永逸的方法？
方法我倒是替你想到了，而且适用各种不同场景。如：
- 多环境之间的切换
- 有时候服务器需要他本地调试怎么办？手动输入不是问题
- 打包老是忘记关闭环境切换？那就只在debug模式才能切换，测试包你也是可以打debug包的。
配置域名也非常简单，只需要在 allHostArray 填上你需要切换的环境域名跟备注，在 mainHost 设置默认的域名
在你方便的地方触发下环境切换吧。对只需一句代码
DebugEnvManager.showDebugEnvView()
网络请求获取域名
DebugEnvManager.getHomeHost()
主代码：
class DebugEnvManager: NSObject {
static let mainHost = "https://xxx.com/"
/// 文件地址 视频，图片需要拼接的前缀 默认追加files/
// static let fileHost =
static let allHostArray = [
("外网", mainHost),
("测试", "https://xxx.test.com/"),
("你自己输入吧", "如:http://192.168.1.102:8080/"),
