辞去Cydia应用程序以在非越狱iPhone上安装

Question

I'm part of the apple developer program so I can code sign and install on my device.

Is it possible to take an application from Cydia (it doesn't appear to use mobilesubstrate, it's packaged as a .deb) and re-sign it so I can install it on my non-jailbroken iPhone?

Thanks!

Answer 1

您可以使用内置的codesign终端命令通过键入以下内容来重新签名您的应用：

codesign -fs "iPhone Developer : <your name>" application.app

Answer 2

Probably. Depending on the app. Some applications are just App Store applications (or similar), that were or would be rejected. If it is one of those, extracting the .app file then codesign-ing the binary inside there should get it to work.

However, many Cydia apps require themselves to be installed to the "system" directory (/Applications), so won't work in the App Store/Developer directories, and also may require root access or access to other files that Apple would deny.

Your best bet, if you want to run one of these apps, is to jailbreak.

Answer 3

As long as the application does not go anywhere beyond the Sandbox - you can resign it using your developer account. You don't need the source for that.

You might check www.aironapp.com it does the recodesigning procedure. All you need to do is configure your Developers Apple Account there.

Answer 4

If the full source code for that app is provided in the .deb (which you can extract and see) then you could probably resign the code and put it on your device. However, you would need everything that the actual developer had, which as I understand does not happen. (If you compile an iPhone app and look at the .app package contents, you'll notice all your resources, but no .h /. files, just a data.momd file.

If you do some tricky decompiling, perhaps you could get all the files you need, but that's a different story.
