arrays - 通过本地化改变ImageView的图片

Question

您好，我有一个 imageView 来显示一些图片。我想为每种语言显示不同的图片。因此，当用户本地化为德语时，他得到的图片与本地化为英语的用户不同。

这是我的代码。如何为每个本地化制作多个 imageArray？

谢谢

override func viewDidLoad() {

    super.viewDidLoad()

    mainScrollView.frame = view.frame


    imageArray = [#imageLiteral(resourceName: "help0"), #imageLiteral(resourceName: "help1"), #imageLiteral(resourceName: "help2"), #imageLiteral(resourceName: "help3"), #imageLiteral(resourceName: "help4")]



    for i in 0..<imageArray.count{

        let imageView = UIImageView()
        imageView.image = imageArray[i]
        imageView.contentMode = .scaleAspectFit
        let xPosition = self.view.frame.width * CGFloat(i)

        imageView.frame = CGRect(x: xPosition , y: 0, width: self.mainScrollView.frame.width, height: self.mainScrollView.frame.height)



        mainScrollView.contentSize.width = mainScrollView.frame.width * CGFloat(i + 1)
        mainScrollView.addSubview(imageView)

        self.view.sendSubview(toBack: mainScrollView)

    }

你可以通过使用 NSLocalizedString 来做到这一点，所以你声明你的数组是这样的:

let help0 = UIImage(named: NSLocalizedString("help0", comment: ""))
let help1 = UIImage(named: NSLocalizedString("help1", comment: ""))
let help2 = UIImage(named: NSLocalizedString("help2", comment: ""))
let help3 = UIImage(named: NSLocalizedString("help3", comment: ""))
let help4 = UIImage(named: NSLocalizedString("help4", comment: ""))

let imageArray = [help0, help1, help2, help3, help4]

然后在您的示例 ENG 和 GER 中添加您的本地化语言，并在这些文件中添加您想要使用的图像，就像这样(a guide 如何添加本地化):

Localization for English:
"help0" = "help0Eng";
"help1" = "help1Eng";
etc...

Localization for German:
"help0" = "help0Ger";
"help1" = "help1Ger";
etc...

而你的help0Eng、help0Ger等就是你的Assets.xcassets中图片的名称。所以会发生以下情况:

1. NSLocalizedString("help0", comment: "") 将本地化到所选语言的正确文件中
2. 该图像名称将用于 help0
