I want to reduce compiled file size of ios ipa file.

I get "How to reduce" way: How to reduce the size of my iPhone application?

But I want to know "How to analyze" way:

My image is 

$ du /path/to/app
100 /path/to/app/images
150 /path/to/app/sounds

And I wan to reduce file size on effective point. Visualization is more good!: http://www.lomont.org/Software/Utilities/DiskInfo/DiskInfo.png

I know I should delete files which is not used but is linked project...

I have used a tool called [ImageOptim] (http://imageoptim.com/xcode.html)

It incorporates a number of tools inside which crush your png files significantly (in my case it was between 25% to 50%) and had reduced the size of my app of around 0.6 mb

One thing to remember is to disable Xcode's PNG optimization.

There is no magic way to reduce the file size of ipa file.

What you can do to reduce the size are just as you said,

  • Remove any unnecessary files
  • If you have a lot of images, consider using PNGCRUSH to reduce file size of images
  • If you have a lot of sound files, consider using compressed audio file such as MP3, also, consider changing to mono instead of stereo. Bit rates of around 96K is still pretty decent.

  • When optimizing images you need to [fix Xcode config](http://imageoptim.com/xcode.html), otherwise Xcode will undo the optimizations! – Kornel Mar 22 '12 at 14:42
