right-to-left - iOS 应用程序中的 LTR 到 RTL [不关闭应用程序]

Question

在应用程序中更改语言时，我需要根据所选语言更改应用程序布局。

例如，基础语言是英语；当用户将其更改为阿拉伯语时，我需要根据 RTL 更改 UI。

故事板或 ViewController 中是否有任何特定设置来实现 LTR 和 RTL？

Answer 1

在不关闭应用程序 Swift 3.0 的情况下管理 RTL 和 LTR。

//RTL

UIView.appearance().semanticContentAttribute = .forceRightToLeft UINavigationBar.appearance().semanticContentAttribute = .forceRightToLeft

//applicationNavigationController 是应用程序默认导航控制器 if let applicationNavigationController = storyboard?.instantiateViewController(withIdentifier: "root") { UIApplication.shared.keyWindow?.rootViewController = applicationNavigationController

LTR//

UIView.appearance().semanticContentAttribute = .forceLeftToRight UINavigationBar.appearance().semanticContentAttribute = .forceLeftToRight if let applicationNavigationController = storyboard?.instantiateViewController(withIdentifier: "root") { UIApplication.shared.keyWindow?.rootViewController = applicationNavigationController

// 处理 MMDrawer 时的附加提示。

应用委托

var centerContainer:MMDrawerController?

在一个 ViewController 中实现 MMDrawer 代码。

让 appdelegate=UIApplication.shared.delegate 为！应用委托

    let mainStoryboard:UIStoryboard=UIStoryboard(name: "Main", bundle: nil)

    let centerViewController = mainStoryboard.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
    let leftViewController = mainStoryboard.instantiateViewController(withIdentifier: "LeftSideMenuViewController") as! LeftSideMenuViewController



    let leftSideNav = UINavigationController(rootViewController: leftViewController)
    let centerNav = UINavigationController(rootViewController: centerViewController)


    appdelegate.centerContainer = MMDrawerController(center: centerNav, leftDrawerViewController: leftSideNav)

    appdelegate.centerContainer?.maximumLeftDrawerWidth = 250.0


    appdelegate.centerContainer!.openDrawerGestureModeMask = MMOpenDrawerGestureMode.panningCenterView
    appdelegate.centerContainer!.closeDrawerGestureModeMask = MMCloseDrawerGestureMode.all

    //////////
    self.navigationController?.pushViewController(appdelegate.centerContainer!, animated: false)
