如何在Swift中使NSBundle中的缓存无效 [英] How to invalidate cache from NSBundle in Swift

问题描述

当我尝试本地化字符串时，它会返回以前的值.我在此帖子中实际上必须使缓存无效.

When I try to localize a string it returns previous value. I found in this post that you actually have to invalidate the cache.

这或多或少是我尝试的代码.在 localizableStringsPath 内部，该文件实际上显示了我从inet下载的翻译，但bundle返回了先前的值.我必须关闭该应用程序，然后从 localizableStringsPath 捆绑返回以前的值.

More or less this is the code I tried. Inside localizableStringsPath the file actually shows the translations I downloaded from inet, but bundle returns the previous value. I have to close the app, and then bundle return the previous value from localizableStringsPath.

func translateFromInet(key: String) -> String {
    let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first ?? ""
    let localizableStringsPath = documentsPath + "/Localizable.strings" // This file is downloaded from the inet with custom translations
    let bundle = Bundle(path: documentsPath)
    return bundle!.localizedString(forKey: key, value: nil, table: nil)
}

推荐答案

将可本地化的文件另存为 Localizable.nocache.strings 而不是 Localizable.strings .您可以在Apple文档中找到更多详细信息: developer.apple.com-资源编程指南-字符串资源

Save the localizable file as Localizable.nocache.strings instead of Localizable.strings. You can find more details inside the apple documentation: developer.apple.com - Resource Programming Guide - String Resources

• 您可以将下载的文件重命名为 Localizable.nocache.strings ，然后按如下所示对代码进行

• You can rename the downloaded file to Localizable.nocache.strings then make edit to your code as the following:

func translateFromInet(key: String) -> String {
    let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first ?? ""
    let localizableStringsPath = documentsPath + "/Localizable.nocache.strings" // This file is downloaded from the inet with custom translations
    let bundle = Bundle(path: documentsPath)
    return bundle!.localizedString(forKey: key, value: nil, table: nil)
}
