Thanks to others members and some search, I've found the answers to the 2 questions:

  • (Big thanks to @Nate for this repply), it's possible to use NSTask in ios by importing the header file into the application project. The syntax is the same as the use in mac os x application but you can find some help here

  • An app placed into /Applications/ haven't the admin rights. For doing this, you have to:

1) In the main() function add setuid(0); and setgid(0);

2) Build the app normally.

3) If you build an app named HelloWorld, Xcode will create a
HelloWorld.app directory, with a file named HelloWorld inside it, which
is executable. Rename this executable to, for example, MobileHelloWorld

4) Once you ve done that, create a new file in the HelloWorld.app directory called HelloWorld, and edit it with a text editor to give it this content:

#!/bin/bash
dir=$(dirname "$0")
exec "${dir}"/MobileHelloWorld "$@"

That script will then be run when you tap the app's icon, because in the app's Info.plist file, the name of the executable is

<key>CFBundleExecutable</key>
<string>HelloWorld</string>

and HelloWorld is now a shell script, which invokes MobileHelloWorld, the renamed binary executable file.

5) In terminal, navigate to the app bundle.

6) chmod 0775 the original executable file and chmod 6775 the copied executable file.

7) Copy the app bundle to /Applications to a device. Restart SpringBoard and you should be good to go. If the app doesn't launch then repeat step 5 & 6 on the device.

For this questions, all credits goes to (again :P) @Nate (here) and @JonasG (here)
