Hey guys
Recently, I saw in more or less each Application (for example DoodleJump, AngryBirds, DoodleScore, etc.) a file which was between 1 - 10MB large. It hadn't also a type. It was described as "file". Every other files were between 1 to 50KB (from type .nib, .plist). I didn't find also the files with the contains of the game. I suspect, it's a container. So, I wanted to unpack it with WinRAR. But WinRAR open this file with the Editor :(
Is there any possibility to unpack it, if it's a container?
Thx for help

P.S. Sorry about my bad english ;)

Sounds like your talking about the actual executable for each app.

Its an executable obj-c binary. Its the heart of the app. Its not a container.

But why show the file me things like:

?èXXð?éfIyD hXð?édI"yD hXð?ébKcI "{DyDh hèXXð|é_IyD h^HxD hXðré\IyD hXðné? ???YKÀ"Ò{DQFWL|D?h

Could it be, cause I'm using Windows?

Edit: Or could I see the right file contents with a program?

It sounds like he wants to reverse engineer the app and then remake it.

There a way to do just about anything, but it's not always easy.

yeah, i wanted a one button click to open it in xcode or whatnot lol. Sounds like you may as well just learn all the mad shit rather than spend the time pulling it appart?
