I installed "Class Dump" from Cydia to get application header files.
But there is a problem.
I can use class-dump in default app.
For example, I ran this command:
class-dump -H /Applications/MobileSafari.app/MobileSafari -o /Headers/safari
and could get header files in "/Headers/safari/".
But AppStore app, for example,
I ran this command:class-dump -H /var/mobile/Applications/BFF...../Dropbox.app/Dropbox -o /Headers/dropbox
and terminal works, but garbled characters appeared (ScreenShot) and then terminal crashed.
How can I get AppStore app header files?
All AppStore apps are encrypted. In order to use class-dump you need to decrypt (crack) them. You have two options:
On the other hand, built-in apps like Safari are not encrypted.
