localization

localization is a skill for Claude Code, Codex from wangjianqi/AppStore. It costs 32 tokens per session (2,199 once invoked), scanned A, original, MIT.

A guide to adding multiple languages to an iOS app, including translated text, language switching, and different word forms such as singular and plural. It uses Apple’s localization files, including Localizable.strings and strings dictionaries.

In plain words
What is it for?
Use it to organize Chinese and English text, assign reusable translation keys, format translated messages with values, handle plurals, and test internationalized screens.
Why use it?
It prevents user-visible text from being hard-coded in one language and helps keep translations consistent across the app.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

localization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

  • 次要语言:英文(en)
  • 语言文件位置:Resources/zh-Hans.lproj/Resources/en.lproj/

文案管理规范

Key 命名规则

  • 所有用户可见文字必须走本地化,禁止硬编码中文或英文字符串
  • Key 命名:模块.组件.含义(全小写,点分隔)
  • 相同含义的按钮/标签用统一 Key,禁止重复定义
camera.permission.title = "需要相机权限"
camera.permission.message = "请在设置中开启相机权限,以使用录制功能"
camera.button.start = "开始录制"
camera.button.stop = "停止录制"
settings.title = "设置"
settings.button.logout = "退出登录"
paywall.title = "升级 Pro"
paywall.trial.days = "免费试用 %d 天"

代码使用

标准用法

label.text = NSLocalizedString("camera.button.start", comment: "录制按钮")

项目封装(推荐)

extension String {
    var localized: String {
        NSLocalizedString(self, bundle: .main, comment: "")
    }

    func localized(with arguments: CVarArg...) -> String {
        String(format: self.localized, arguments: arguments)
    }
}

// 使用
label.text = "camera.button.start".localized
let text = "paywall.trial.days".localized(with: 7)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
