在越狱的iPhone上，我如何以root身份运行命令？

Question

I want to login as a root using system call in Xcode. I try this code without success:

System("su");
System("alpine");

or

System("su root");
System("alpine");

or

System("su root alpine");

When I google it I came to know that this is done using NSTask or NSPipe . Can anybody tell me how it possible to run multiple system commands using NSTask and NSPipe ?

Please give me some hints about this or another method to do this. I am using this application on jailbroken iPhone.

Some more details are here .

If you want to launch something as root you may use sudo .

Example of it's usage in one line with the password:

echo <password> | sudo -S <command>
