iOS 查漏报错 FBRetainCycleDetector崩溃
pod install 遇到终端报错：
[!] An error occurred while processing the post-install hook of the Podfile.
Permission denied @ rb_sysopen - Pods/FBRetainCycleDetector/fishhook/fishhook.c
pod 'MLeaksFinder', :configurations => ['Debug']
添加 MLeaksFinder 之后 程序会崩溃，
在Podfile文件末尾添加下面代码即可
因为MLeaksFinder 依赖 FBRetainCycleDetector，但是 FBRetainCycleDetector中的代码有需要更新的地方，所以导致了crash，可通过在Podfile中最下面添加下面代码，完美解决
require "fileutils"
post_install do |installer|
## Fix for XCode 12.5
find_and_replace("Pods/FBRetainCycleDetector/FBRetainCycleDetector/Layout/Classes/FBClassStrongLayout.mm",

end
def find_and_replace(dir, findstr, replacestr)
Dir[dir].each do |name|
FileUtils.chmod("+w", name) #add
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))
