Cocoapods frameworks version number fix

This script changes all Cocoapods frameworks' version numbers to match the app's plist, which is required as of 21 Oct 2015.

It fixes the following error:

ERROR ITMS-90062 "This bundle is invalid. The value for key CFBundleShortVersionString in the Info.plist file must contain a higher version than that of the previously approved version".  

Thanks to @orta for the initial idea!

Install

1. Add this script at the end of your Podfile.

   post_install do |installer| app_plist = "MyApp/Info.plist" plist_buddy = "/usr/libexec/PlistBuddy"

    version = `#{plist_buddy} -c "Print CFBundleShortVersionString" "#{app_plist}"`.strip
    
    puts "Updating CocoaPods frameworks' version numbers to #{version}"
   
    installer.pods_project.targets.each do |target|  
        `#{plist_buddy} -c "Set CFBundleShortVersionString #{version}" "Pods/Target Support Files/#{target}/Info.plist"`  
    end  
   

   end

2. Update the path in app_plist variable so that it matches the path to your app's .plist file.

3. Run pod install afterwards.
