语言管理器用于在不停机的情况下更改应用语言

屏幕截图

用法

首先记得将 Localizable.strings 添加到您的项目中，在添加 Localizable.strings 文件后，选择它，然后转到文件检查器，在本地化下面按下本地化，然后转到 项目 > 本地化，然后添加您想要支持的的语言（例如阿拉伯语），会出现对话框询问您想要本地化的资源文件，只选择 Localizable.strings 文件。
 
现在，转到您的 storyboard，并添加 UILable 并向其添加文本，例如 "Hello !"，然后转到您的 Localizable.strings 文件，展开它，您将找到英语和阿拉伯语的 Localizable 字符串文件，对于英语，只放入您在 storyboard 的 UILabel 中放入的字符串这一行
"Hello !" = "Hello !";
对于阿拉伯语文件
"Hello !" = "مرحبا !";

LanguageManger.shared.defaultLanguage = .en

如果您想更改语言，使用 setLanguage(language:) 方法，将其传递给新的语言

@IBAction func changeLanguage(_ sender: UIButton) {

let selectedLanguage:Languages = sender.tag == 1 ? .en : .ar

// change the language
LanguageManger.shared.setLanguage(language: selectedLanguage)

// then you must to pop all view controllers and return to root view controller then re set the root view controller 
UIApplication.topViewController!.dismiss(animated: true) {
let delegate = UIApplication.shared.delegate as! AppDelegate
let storyboard = UIStoryboard(name: "Main", bundle: nil)
delegate.window?.rootViewController = storyboard.instantiateInitialViewController()
}
}

*注意
语言管理器帮助您在应用中支持多种语言，但是有一些情况您需要自己处理，比如某些 UILabel 或 UITextField 不改变方向，因此您需要这样做。例如

textAlignment = LanguageManger.shared.isRightToLeft ? .right : .left.

安装

只需将 LanguageManger.swift 添加到您的项目中

注意

如果您能给我反馈或建议，我会非常高兴，谢谢
