Where do I implement the function?

[jweinraub]

Do I put the alert into a viewDidAppear block?

-(void)viewDidAppear:(BOOL)animated
{
     if ([DTTJailbreakDetection isJailbroken]) 
    {
         // code
    }
}

If I do that, the main view still loads. Can I keep it at the LaunchScreenStoryBoard, so it doesn't even show the app, if i wanted?

Pardon my ignorance on this subject I am learning and seeing how this works.

Thanks

If you want to your app to crash if it runs on a jailbroken device:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
     if ([DTTJailbreakDetection isJailbroken]) {
         exit(1);
    }
    return YES;
}
