Question

I want to build lock app if the user didn’t do any thing with the app after 2 min.

there is anything that can inform me every time the user made touch,scroll,pinch… on every screen in the app?

Create a subclass of UIApplication. Modify the following line in the main.m file:

int retVal = UIApplicationMain(argc, argv, @"CustomApplication", nil);

Where CustomApplication is your UIApplication subclass name.

Now you can override the -(void)sendEvent:(UIEvent *)eventmethod in your custom subclass. This method would be called for each and evrery event of the application, including the user interaction events.
