1.写一个脚本，搜寻代码里所有的用的多语言key的地方

import re
import os

def extract_keys_from_file(file_path):
    with open(file_path, 'r') as file:
        content = file.read()

        # 匹配 DEF_LOCALIZED_STRING
        matches_def_localized = re.findall(r'DEF_LOCALIZED_STRING\(key: "(.*?)"\)', content)

        # 匹配 self.dontHaveLabel.hc_Text = "login.createAccount"
        matches_hc_text = re.findall(r'self\.(\w+)\.hc_Text\s*=\s*"(.*?)"', content)

        # 匹配 signUpButton.hc_SetTitle("register.signUpBtn", for: .normal)
        matches_hc_set_title = re.findall(r'\.hc_SetTitle\("(.*?)",\s*for:\s*\.\w+\)', content)

        # 匹配 emailTF.hc_PlaceholderSwitch = "login.emailAddress"
        matches_hc_placeholder_switch = re.findall(r'\.hc_PlaceholderSwitch\s*=\s*"(.*?)"', content)

        return matches_def_localized + matches_hc_text + matches_hc_set_title + matches_hc_placeholder_switch

def main():
    # 使用当前脚本所在的目录作为起始点
    script_directory = os.path.dirname(os.path.abspath(__file__))

    # 存储所有的 key，使用 set 来自动去重
    all_keys = set()

    # 遍历当前目录及其子目录下的所有 Swift 文件
    for root, dirs, files in os.walk(script_directory):
        for file in files:
            if file.endswith('.swift'):
                file_path = os.path.join(root, file)
                keys = extract_keys_from_file(file_path)
                if keys:
                    all_keys.update(keys)

    # 输出去重后的 key
    print('Unique Keys:')
    for key in all_keys:
        if isinstance(key, tuple) and len(key) == 2:
            # 输出元组的第二个元素
            print(key[1])
        else:
            print(key)

if __name__ == "__main__":
    main()

将以上代码放到项目根目录执行后，即可得到代码里所有用到的key 并输出出来 注意

以下部分代码是根据项目里多语言方法前缀搜索

    # 匹配 DEF_LOCALIZED_STRING
    matches_def_localized = re.findall(r'DEF_LOCALIZED_STRING\(key: "(.*?)"\)', content)

    # 匹配 self.dontHaveLabel.hc_Text = "login.createAccount"
    matches_hc_text = re.findall(r'self\.(\w+)\.hc_Text\s*=\s*"(.*?)"', content)

    # 匹配 signUpButton.hc_SetTitle("register.signUpBtn", for: .normal)
    matches_hc_set_title = re.findall(r'\.hc_SetTitle\("(.*?)",\s*for:\s*\.\w+\)', content)

    # 匹配 emailTF.hc_PlaceholderSwitch = "login.emailAddress"
    matches_hc_placeholder_switch = re.findall(r'\.hc_PlaceholderSwitch\s*=\s*"(.*?)"', content)

根据自己的的项目会有调整

比如自己的项目是通过

let localizedString = NSLocalizedString("Hello", comment: "Greeting")

就

    matches_def_localized = re.findall(NSLocalizedString(\ "(.*?)"\)', content)

2.写一个脚本，搜寻Localizable.strings的所有key

import re
import os

def extract_keys_from_strings_file(file_path):
    with open(file_path, 'r', encoding='latin-1') as file:
        content = file.read()
        matches = re.findall(r'"(.*?)"\s*=\s*".*?";', content)
        return matches

def main():
    # 使用当前脚本所在的目录作为起始点
    script_directory = os.path.dirname(os.path.abspath(__file__))

    # 存储所有的 key，使用 set 来自动去重
    all_keys = set()

    # 遍历当前目录及其子目录下的所有 Localizable.strings 文件
    for root, dirs, files in os.walk(script_directory):
        for file in files:
            if file == 'Localizable.strings':
                file_path = os.path.join(root, file)
                keys = extract_keys_from_strings_file(file_path)
                if keys:
                    all_keys.update(keys)

    # 输出所有的 key
    print('All Keys in Localizable.strings:')
    for key in all_keys:
        print(key)

if __name__ == "__main__":
    main()

此文件也是放到根目录（会扫描项目所有的Localizable.strings）下，或者需要扫描的Localizable.strings的同级目录

3.组合2个脚本，把得到的2个数组相减得到最后的结果

import re
import os

def extract_keys_from_file(file_path):
    with open(file_path, 'r') as file:
        content = file.read()

# 匹配 DEF_LOCALIZED_STRING，不管是否有 self.
    matches_def_localized = re.findall(r'(?:self\.)?DEF_LOCALIZED_STRING\(key: "(.*?)"\)', content)

# 匹配不管是否有 self. 的情况，例如：dontHaveLabel.hc_Text = "login.createAccount" 或 self.dontHaveLabel.hc_Text = "login.createAccount"
    matches_hc_text = re.findall(r'(?:self\.)?(\w+)\.hc_Text\s*=\s*"(.*?)"', content)

# 匹配不管是否有 self. 的情况，例如：signUpButton.hc_SetTitle("register.signUpBtn", for: .normal)
    matches_hc_set_title = re.findall(r'(?:self\.)?\.hc_SetTitle\("(.*?)",\s*for:\s*\.\w+\)', content)

# 匹配不管是否有 self. 的情况，例如：emailTF.hc_PlaceholderSwitch = "login.emailAddress"
    matches_hc_placeholder_switch = re.findall(r'(?:self\.)?\.hc_PlaceholderSwitch\s*=\s*"(.*?)"', content)

    return matches_def_localized + matches_hc_text + matches_hc_set_title + matches_hc_placeholder_switch


def extract_keys_from_strings_file(file_path):
    with open(file_path, 'r', encoding='latin-1') as file:
        content = file.read()
        matches = re.findall(r'"(.*?)"\s*=\s*".*?";', content, re.DOTALL)
        return matches

def main():
    # 使用当前脚本所在的目录作为起始点
    script_directory = os.path.dirname(os.path.abspath(__file__))

    # 存储所有的项目 key，使用 set 来自动去重
    project_keys = set()

    # 存储所有的 Localizable.strings key，使用 set 来自动去重
    localizable_keys = set()

    # 遍历当前目录及其子目录下的所有 Swift 文件
    for root, dirs, files in os.walk(script_directory):
        for file in files:
            if file.endswith('.swift'):
                file_path = os.path.join(root, file)
                # print(f"处理Swift文件：{file_path}")
                keys = extract_keys_from_file(file_path)
                # print(f"找到的键：{keys}")
                if keys:
                    # 处理可能是元组的情况，取元组的第2位
                    project_keys.update(key[1] if isinstance(key, tuple) else key for key in keys)

    # 遍历当前目录及其子目录下的所有 Localizable.strings 文件
    for root, dirs, files in os.walk(script_directory):
        for file in files:
            if file == 'Localizable.strings':
                file_path = os.path.join(root, file)
                keys = extract_keys_from_strings_file(file_path)
                if keys:
                    localizable_keys.update(keys)


    print("项目 keys:")
    print(project_keys)

    print("\nLocalizable.strings keys:")
    print(localizable_keys)
    # 寻找在项目中但不在 Localizable.strings 中的 key
    missing_keys = project_keys - localizable_keys

    print("\nmissing_keys:")
    print(missing_keys)

    # 输出结果
    # print("Keys in project but not in Localizable.strings:")
    keys_array = list(missing_keys)
    if keys_array:
        print("扫描结果 --- Localizable.strings文件缺失的key: " + "   |   ".join(keys_array))
    else:
        print("扫描结果 --- Localizable.strings文件里没有缺失的key")

if __name__ == "__main__":
    main()
