Check whether the iPhone is jailbroken.

 

How can I check whether a jailbreak exists? The easiest way is to check whether your device has a directory for jailbreak. The following is the code.

 

Detectdevice. h

 

View plaincopy to clipboardprint?

1. @ Interface uidevice (helper)
2. -(Bool) isjailbroken;
3. @ End

@ Interface uidevice (helper)-(bool) isjailbroken; @ end 

Detectdevice. m

View plaincopy to clipboardprint?

1. @ Implementation uidevice (helper)
2. -(Bool) isjailbroken {
3. Bool jailbroken = no;
4. Nsstring * cydiapath = @ "/applications/cydia. app ";
5. Nsstring * aptpath = @ "/private/var/lib/APT /";
6. If ([[nsfilemanager defaultmanager] fileexistsatpath: cydiapath]) {
7. Jailbroken = yes;
8. }
9. If ([[nsfilemanager defaultmanager] fileexistsatpath: aptpath]) {
10. Jailbroken = yes;
11. }
12. Return jailbroken;
13. }
14. @ End

@ Implementation uidevice (helper)-(bool) isjailbroken {bool jailbroken = no; nsstring * cydiapath = @ "/applications/cydia. APP "; nsstring * aptpath = @"/private/var/lib/APT/"; if ([[nsfilemanager defaultmanager] fileexistsatpath: cydiapath]) {jailbroken = yes ;} if ([[nsfilemanager defaultmanager] fileexistsatpath: aptpath]) {jailbroken = yes;} return jailbroken;} @ end 

 

Then, call [uidevice currentdevice] isjailbroken] in your code. If yes is returned, the code is cracked. If no is returned, the Code is not cracked.
