Swift 4.0中的情节提要板本地化 [英] storyboard localization in swift 4.0

问题描述

我想用快速的语言实现情节提要的本地化.(意味着我想本地化修复标签和按钮文本)

我已经对NSLocalizedString有所了解，但是我不想为固定文本标签编码

例如

  NSLocalizedString("Welcome"，评论:") 

我已经为特定语言添加了Localizable.strings文件和Main.string文件.但我无法成功实现本地化

解决方案

我已将此库用于应用内本地化.这是非常容易使用.

3)运行并测试

I want to implement storyboard localization in swift language. (means I want to localization for fix label and button text)

I have already idea about NSLocalizedString but I dont want to code for fix text Label

for e.g

NSLocalizedString("Welcome", comment: "")

I have already add Localizable.strings file as well as Main.string file for particular language. but I can not success in implement Localization

解决方案

I have used this library for in - app localisation. Which is very easy to use.

Now For Storyboard support I have Created Following extension that is IBDesignable So you can easily provide localised text from storyboard itself

1 ) Add This into new swift file

import Localize_Swift

@IBDesignable class LocalizableLabel: UILabel {

    @IBInspectable var table :String? // Table 
    @IBInspectable var key:String? // KEY 

    @IBInspectable var extraTextToAppend:String? // Some text need to append , if any


    override func awakeFromNib() {
        guard let key = key else {return}
        self.text = key.localized(using: table)
        NotificationCenter.default.addObserver(self, selector: #selector(setText), name: NSNotification.Name(LCLLanguageChangeNotification), object: nil)

        if let extraText = self.extraTextToAppend, let text = self.text {
            self.text = text + extraText
        }

    }

    @objc func setText () {
        guard let key = key else {return}
        self.text = key.localized(using: table)

        if let extraText = self.extraTextToAppend, let text = self.text {
            self.text = text + extraText
        }


    }

}

@IBDesignable class LocalizableButton: UIButton {

    @IBInspectable var table :String?
    @IBInspectable var key:String?

    override func awakeFromNib() {
        guard let key = key else {return}
        self.setTitle(key.localized(using: table), for: .normal)

        if let attributedText = self.attributedTitle(for: .normal) {
            let mutableAttributedText = NSMutableAttributedString(attributedString: attributedText)
            mutableAttributedText.replaceCharacters(in: NSMakeRange(0, mutableAttributedText.length), with: key.localized(using: table))
            self.setAttributedTitle(mutableAttributedText, for: .normal)
        }

        NotificationCenter.default.addObserver(self, selector: #selector(setText), name: NSNotification.Name(LCLLanguageChangeNotification), object: nil)

    }

    @objc func setText () {
        guard let key = key else {return}
        self.setTitle(key.localized(using: table), for: .normal)

        if let attributedText = self.attributedTitle(for: .normal) {
            let mutableAttributedText = NSMutableAttributedString(attributedString: attributedText)
            mutableAttributedText.replaceCharacters(in: NSMakeRange(0, mutableAttributedText.length), with: key.localized(using: table))
            self.setAttributedTitle(mutableAttributedText, for: .normal)

        }
    }

}



@IBDesignable class LocalizeUINavigationItem: UINavigationItem {

    @IBInspectable var table :String?
    @IBInspectable var key:String?

    override func awakeFromNib() {
        guard let key = key else {return}
        self.title = key.localized(using: table)
        NotificationCenter.default.addObserver(self, selector: #selector(setText), name: NSNotification.Name(LCLLanguageChangeNotification), object: nil)

    }

    @objc func setText () {
        guard let key = key else {return}
        self.title = key.localized(using: table)

    }

}


@IBDesignable class LocalizableUITextField: UITextField {

    @IBInspectable var table_placeholder :String?
    @IBInspectable var key_place_holder:String?

    override func awakeFromNib() {
        guard let key = key_place_holder else {return}
        self.placeholder = key.localized(using: table_placeholder)
        NotificationCenter.default.addObserver(self, selector: #selector(setText), name: NSNotification.Name(LCLLanguageChangeNotification), object: nil)

    }

    @objc func setText () {
        guard let key = key_place_holder else {return}
        self.placeholder = key.localized(using: table_placeholder)

    }

}

2) Goto Storyboard set class to label and provide the key

3) Run and test
