如何在编程中以编程方式更改特定segue的标识符名称？

我发现了这种方法，但对我没有用： SWrevealviewcontroller：从左到右切换滑动菜单方向编辑：

我有一个名为SWreavealviewcontroller的菜单，并希望在英语情况下从左侧显示，在阿拉伯语情况下从右侧显示。

您不能通过编程方式更改segue名称。因为segue指定了应用程序故事板文件中两个视图控制器之间的转换，您可以在故事板中对其进行重命名。

您可以在视图控制器之间定义多个segue，并像这样通过编程方式调用segue：

performSegue(withIdentifier: "yourSegueID", sender: nil)

针对您的问题：

You can create two segues between your view controllers, and give two different segue identifier names to them (eg. englishSegue and arabicSegue).
Create a variable for your segue identifier. (You will use it to select which of your segue should be triggered.)
Control your language in your view controller (eg. in your viewDidLoad function or where you should control it) programmatically and set your language variable as English or Arabic.

After that you can trigger it anywhere you want it. For example in a button click:

if (yourIdentifier == "English") {
    performSegue(withIdentifier: "englishSegue", sender: nil)
} else if (yourIdentifier == "Arabic") {
    performSegue(withIdentifier: "arabicSegue", sender: nil)
}
