[移动开发]iOS Cannot initialize a parameter of type ‘id＜NSCopying＞ _Nonnull‘ with an rvalue of type ‘Class‘

前言

今天在接入内存泄漏检测工具MLeaksFinder
发现一个错误如下：

Cannot initialize a parameter of type 'id<NSCopying> _Nonnull' with an rvalue of type 'Class'

查找一下资料官方说明

Xcode 12.5 compile error: Cannot initialize a parameter of type 'id<NSCopying> _Nonnull' with an rvalue of type

因为我项目中是用混合开发，还继承了许多其他的库，大家可以参考一下：

post_install do |installer|
    ## Fix for XCode 12.5
    find_and_replace("Pods/FBRetainCycleDetector/FBRetainCycleDetector/Layout/Classes/FBClassStrongLayout.mm",
      "layoutCache[currentClass] = ivars;", "layoutCache[(id<NSCopying>)currentClass] = ivars;")
end

def find_and_replace(dir, findstr, replacestr)
  Dir[dir].each do |name|
      text = File.read(name)
      replace = text.gsub(findstr,replacestr)
      if text != replace
          puts "Fix: " + name
          File.open(name, "w") { |file| file.puts replace }
          STDOUT.flush
      end
  end
  Dir[dir + '*/'].each(&method(:find_and_replace))
end

最终方法：

post_install do |installer|
  ## Fix for XCode 12.5
  find_and_replace("Pods/FBRetainCycleDetector/FBRetainCycleDetector/Layout/Classes/FBClassStrongLayout.mm",
    "layoutCache[currentClass] = ivars;", "layoutCache[(id<NSCopying>)currentClass] = ivars;")
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
      #消除TwitterCore警告
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/-framework "TwitterCore"/, "")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }

      if config.name == 'Debug'
        config.build_settings['OTHER_SWIFT_FLAGS'] = ['$(inherited)', '-Onone']
        config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Owholemodule'
      end

      if config.name == 'Test'
        config.build_settings['OTHER_SWIFT_FLAGS'] = ['$(inherited)', '-Onone']
        config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Owholemodule'
      end

    end
  end
  installer.pods_project.build_configurations.each do |config|
    config.build_settings[‘EXCLUDED_ARCHS[sdk=iphonesimulator*]’] = ‘arm64’
  end
end


def find_and_replace(dir, findstr, replacestr)
  Dir[dir].each do |name|
      text = File.read(name)
      replace = text.gsub(findstr,replacestr)
      if text != replace
          puts "Fix: " + name
          File.open(name, "w") { |file| file.puts replace }
          STDOUT.flush
      end
  end
  Dir[dir + '*/'].each(&method(:find_and_replace))
end

注意：

写完后需要重新pod install一下才能生效，不然是不会生效的！！！
