• How to detect that the app is running on a jailbroken device? [duplicate] 11 answers

I am developing an iPhone application which is used for business purposes and it is storing many number of records in SQlite database. So my client don't want the app to run on the jailbroken devices.

So how to identify the jail broken devices during the app launch and preventing the user from proceeding further by showing some message.

Thanks in advance.

Answer 1

You can detect through code that if the app is running on a jail broken device or not.
Through that way you can pop up a alert and close the app.
You can do whatever you want to do.

Here is a tutorial for it.

Detection

NSString *filePath = @"/Applications/Cydia.app";
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
{
   // do something useful
}

Also if you want complete solution you can see in tapjoy sdk code.
