安装 BartyCrouch通过 Homebrew ：

Install BartyCrouch via Homebrew:

增量更新您的 Localizable.strings 文件：

$ bartycrouch code -p "/path/to/code/directory" -l "/directory/containing/Localizables" -a

这将完全符合您的要求。

This will do exactly what you were looking for.

为了保持您的 Localizable.strings 文件随时间更新我强烈建议您添加构建脚本（有关如何添加构建脚本的说明此处） ：

In order to keep your Localizable.strings files updated over time I highly recommend adding a build script (instructions on how to add a build script here):

if which bartycrouch > /dev/null; then
    # Incrementally update all Storyboards/XIBs strings files
    bartycrouch interfaces -p "$PROJECT_DIR"

    # Add new keys to Localizable.strings files from NSLocalizedString in code
    bartycrouch code -p "$PROJECT_DIR" -l "$PROJECT_DIR" -a -s
else
    echo "warning: BartyCrouch not installed, download it from https://github.com/Flinesoft/BartyCrouch"
fi

除了逐步更新 Localizable.strings 这些文件也会确保您的Storyboards / XIBs字符串文件保持更新并添加新密钥。

In addition to incrementally updating your Localizable.strings files this will also make sure your Storyboards/XIBs Strings files stay updated with newly added keys.
