1.Make a copy of the .xib in the Finder.
2. Open the copied file in a text editor.
3. Change “com.apple.InterfaceBuilder3.CocoaTouch.XIB” to “com.apple.InterfaceBuilder3.CocoaTouch.iPad.XIB”.
4. Change all instances of “IBCocoaTouchFramework” to “IBIPadFramework”.
5. Search for sizes like {480, 320} and edit them. Or just reopen the file in Xcode and use the GUI to resize items as needed.

Add this to your {App}-prefix.pch file

#ifndef __OPTIMIZE__
#    define NSLog(…) NSLog(__VA_ARGS__)
#else
#    define NSLog(…) {}
#endif

__OPTIMIZE__ only be set on release of build your app.

Quit Safari
Open the Terminal
Move the folder ~/Library/Safari into your Dropbox

mv ~/Library/Safari ~/Dropbox

Make a link from the old location to the new location (for your Mac’s safari to use).

ln -s ~/Dropbox/Safari/ ~/Library/Safari

You’re done on your mac!

before you run this script, you should had ruby env and Xcode.
1. save it with name ‘png’
2. chmod +x png
useage: ./png [ipa file path]

#!/usr/bin/env ruby -wKU
require 'rubygems'
ipa = ARGV.first
puts "useage:png " and return if !ipa or ipa.end_with?("ipa")
name = File.basename(ipa, ".ipa")
# create output folder in you desktop
output = "#{ENV['HOME']}/Desktop/#{name}"
system %Q{mkdir -p "#{output}" && unzip "#{ipa}" -u -d "#{output}"}
Dir.glob(File.join(output, "**", "*.png")).each do |f|
  system %Q{/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/pngcrush -revert-iphone-optimizations -q "#{f}" "#{File.join(output ,File.basename(f))}"}
end
system %Q{find '#{output}' -type f -not \\( -iname "*.png" -or -iname "*.jpg" -or -iname "*.jpeg" \\) -delete}
system %Q{open "#{output}" -a finder}

May be there is another better method to do this. If you have the better way to do it, please tell me.
BTW, below code were successful running in rails3 and ruby 1.8.7

1. first, you should add open4 gem to your Rails project Gemfile

gem 'open4'

and run “bundle install” in terminal to install it in project dir.

2. add below code to config/deploy.rb, please change the namespace name to your own

namespace :your_namespance_name do
  require 'open4'
  rails_root = File.expand_path(File.join(File.dirname(__FILE__), '..'))
  stdin, stdout, stderr = Open4::popen4("cd #{rails_root} && rake -T")
  #please replace :your_namespance_name to your own, this code to grap you special of namespance rake tasks
  stderr.read.scan(/your_namespance_name\:(\w+)/).each do |match|
    desc "rake task named '#{match.last}'"
    task match.last.to_sym, :roles => :app do
      run "cd #{current_path}; RAILS_ENV=production rake railscasts:#{match}"
    end
  end
end

after do that, when you run cap -T in you command shell, you will be found the tasks from rake, also, it can invoked from the remote server of you own.

	CALayer *touchedLayer = [self.view layer];

	// here is an example wiggle
	CABasicAnimation *wiggle = [CABasicAnimation animationWithKeyPath:@"transform"];
	wiggle.duration = 0.1;
	wiggle.repeatCount = 1e100f;
	wiggle.autoreverses = YES;
	wiggle.toValue = [NSValue valueWithCATransform3D:CATransform3DRotate(touchedLayer.transform,0.1, 0.0 ,1.0 ,2.0)];

	// doing the wiggle
//	[touchedLayer addAnimation:wiggle forKey:@"wiggle"];

put this to you ~/.inputrc
