Question

您好，在我的应用程序中，我使用的是https://github.com/Abedalkareem/LanguageManager-iOS窗格，并且已注释了所有更改视图方向的代码，但是当我将语言从英语更改为阿拉伯语时，重新打开菜单时它将更改文本的方向应用程序，它可以从左到右改变方向，当我再次选择英语时，一切都很好，我想禁用，当语言改变时我什么也不想做。

这是我的语言人的代码

                return nil
            }
        }
    }

}

更改语言后我正在这样做，但是什么也没发生

 UINavigationBar.appearance().semanticContentAttribute = .forceLeftToRight
               UITextField.appearance().semanticContentAttribute = .forceLeftToRight
                    UITextView.appearance().semanticContentAttribute = .forceLeftToRight
                   UIView.appearance().semanticContentAttribute = .forceLeftToRight

In Arabic langauge text shows in right side

Answer 1

您可以使用view.contentMode = .right，这将强制内容，无论它是哪种语言，因为使用阿拉伯语时，它将变为左侧。

Answer 2

UIView.appearance（）。semanticContentAttribute = .forceLeftToRight

阿拉伯语变化方向的本地化
