阿拉伯语本地化改变了方向

Question

你好在我的应用程序中，我正在使用这个pod https://github.com/Abedalkareem/LanguageManager-iOS 并且我已经注释了所有改变视图方向的代码，但是当我将语言从英语更改为阿拉伯语时，当我重新打开应用程序时，它会改变文本的方向，当我再次选择英语时，它从左到右改变方向，当我再次选择英语时，一切都很好， 我想禁用，当语言更改时我不想做任何事情。

这是我的语言人的代码

我在更改语言后执行此操作，但什么也没发生

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

在阿拉伯语语言中，文本显示在右侧

Answer 1

UIView.appearance((.semanticContentAttribute = .forceLeftToRight

Answer 2

您可以使用

view.contentMode = .right，无论内容是什么语言，这都会强制内容，因为当它是阿拉伯语时，它会更改为左。
