修改Podfile适配Hikari

[gocse]

当前平台版本

• Xcode Version 10.1 (10B61)
• macOS Mojave 10.14.1
• Hikari LLVM7.0@20190101
• CocoaPods 1.5.3

说明

因为在使用Hikari可能需要修改工程配置，如果工程是使用CocoaPods管理依赖库的话，每个target修改起来将是非常麻烦的，而且每次install或者update就要重新配置一遍，所以写了这个配置，减少重复劳动。该配置主要解决Pods工程在使用Hikari可能出现的以下问题：

1. Undefined symbols ___isOSVersionAtLeast when use #ifdef __IPHONE_11_0 #56
2. -index-store-path cannot specify -o when generating multiple output files
3. ld: loaded libLTO doesn't support -bitcode_hide_symbols: LLVM version 7.0.0 for architecture armv7

使用

在Podfile中整合以下内容就行了

#暂时没找到获取Hikari.xctoolchain路径的方法，因此这个路径根据自己本地安装路径来决定
clang_rt_search_path = '/Library/Developer/Toolchains/Hikari.xctoolchain/usr/lib/clang/10.0.0/lib/darwin/'
post_install do |installer|
    generator_group = installer.pods_project.main_group.find_subpath("Frameworks", true)
    files_references_hash = Hash.new
    installer.pods_project.targets.each do |target|
        #Issues:Undefined symbols ___isOSVersionAtLeast when use #ifdef __IPHONE_11_0 #56
        clang_rt_reference = files_references_hash[target.platform_name.to_s]
        #防止重复添加
        if clang_rt_reference == nil
        #根据target的platform值获取libclang_rt.(ios|tvos|watchos|osx).a
            clang_rt_path = clang_rt_search_path + 'libclang_rt.'+target.platform_name.to_s+'.a'
            clang_rt_reference = generator_group.new_reference(clang_rt_path)
            files_references_hash[target.platform_name.to_s] = clang_rt_reference
        end
        target.add_file_references([clang_rt_reference])
        target.frameworks_build_phase.add_file_reference(clang_rt_reference, true)
        target.build_configurations.each do |config|
            #获取原编译配置文件 PBXFileReference
            origin_build_config = config.base_configuration_reference
            origin_build_config_parser = Xcodeproj::Config.new(origin_build_config.real_path)
            #获取原编译配置文件中的 'LIBRARY_SEARCH_PATHS'
            lib_search_path = origin_build_config_parser.attributes()['LIBRARY_SEARCH_PATHS']
            if lib_search_path != nil
                #merge 'LIBRARY_SEARCH_PATHS'
                config.build_settings['LIBRARY_SEARCH_PATHS'] = lib_search_path + ' ' + clang_rt_search_path
            else
                config.build_settings['LIBRARY_SEARCH_PATHS'] = clang_rt_search_path
            end
            #ld: loaded libLTO doesn't support -bitcode_hide_symbols: LLVM version 7.0.0 for architecture armv7
            config.build_settings['HIDE_BITCODE_SYMBOLS'] = 'NO'
            #Issues:-index-store-path cannot specify -o when generating multiple output files
            config.build_settings['COMPILER_INDEX_STORE_ENABLE'] = 'NO'
        end
    end
end

遇到参数错误?是版本问题?
