ios - lproj 文件尚未加载

Question

我创建了 3 个带有翻译的文件:

• localizable.strings(英文)
• localizable.strings(瑞典语)
• localizable.strings(芬兰语)

我有这个方法来按键获取字符串:

static func localized(key: String) -> String? {
        if let path = Bundle.main.path(forResource: currentLanguage, ofType: "lproj") {
            if let bundle = Bundle(path: path) {
                return NSLocalizedString(key, tableName: nil, bundle: bundle, value: "", comment: "")
            }
        }

        return nil;
    }

但我得到了 "NSBundle (not yet loaded)"

为什么加载不出来，问题出在哪里？

像这样进行扩展

extension String {
func localized(lang:String) -> String {

    let path = Bundle.main.path(forResource: lang, ofType: "lproj")
    let bundle = Bundle(path: path!)

    return NSLocalizedString(self, tableName: nil, bundle: bundle!, value: "", comment: "")

}

let label: UILabel
var language: String?
label.text  = “Hello”.localized(lang:  self.language! )
