越狱的iPhone-超级用户特权 [英] Jailbroken iPhone - root privileges

问题描述

我想制作一个可以管理越狱设备(例如SMS，Notes .db)上某些文件的应用程序，但是我在访问此类文件时遇到了问题.我还只是为了测试自己的技能，例如文件管理器之类的类似应用程序，并且我可以浏览几乎整个文件系统并访问除/var/mobile/Library/中的某些文件夹以外的所有内容.我得到了/var/mobile/Library的内容列表，但在诸如/var/mobile/Library/Notes/，/var/mobile/Library/SBSettings/等子目录中却什么也没有得到，最重要的是: /var/mobile/Library/SMS/或/Notes/不显示任何内容. 当然，当我使用Fugu通过SSH浏览设备时，我拥有了所有内容并可以访问所有内容(例如chmod)

I would like to make an app that will manage some files on jailbroken devices like SMS, Notes .db, but I have problems with accessing such files. I've also made just to test my skills, similar application like your file manager and I could browse almost whole file system and access everything except some folders in /var/mobile/Library/. I get a list of contents of /var/mobile/Library but I get nothing in subdirectories like /var/mobile/Library/Notes/, /var/mobile/Library/SBSettings/, and btw what is most important in my case: /var/mobile/Library/SMS/ or /Notes/ displays nothing. Of course when I browse my device by SSH using Fugu I got everything and have access to everything (like chmod i.e.)

如果您能给我一些建议或源代码，我应该怎么做，我想root的特权不仅可以访问这些文件，还可以更改它们的权限和名称. 我知道如何通常使用NSFileManager进行此类操作，但不能对////SMS/等以上目录中的文件进行操作.

I would be great if you please give me some advices or source code what should I do to have, I guess the root's privileges, not only to access those files, but also change their permissions and names. I know how to make such operations using typically NSFileManager, but not on files from the directories above like /.../SMS/.

我从未开发过严格需要越狱设备来执行给定任务的应用程序.我相信我将需要一些额外的库吗?是真的吗我可以使用Xcode还是可以开发其他应用程序.

I've never developed an application that strictly need jailbroken device to perform the given tasks. I believe I will need some extra libraries? Is it true? Can I use Xcode or there is something else to develop such apps.

我将非常感谢！

推荐答案

即使是越狱，通过Xcode或App Store安装的应用程序仍会被沙箱化.要获得对整个文件系统的只读访问权限，必须将应用程序安装在/Applications/中，而不是在/var/mobile/Applications/中.要获得对整个文件系统的写访问权，该应用程序还必须由root拥有，并使用setuid模式标记

Even when jailbroken, applications installed via Xcode or the App Store are still sandboxed. To get read-only access to the entire filesystem, an application has to be installed in /Applications/ instead of /var/mobile/Applications/. To get write access to the entire filesystem, the application would additionally have to be owned by root and be flagged with the setuid mode
