Question

I need to be able to detect touch events on the keyboard. I have an app which shows a screen which occurs after a certain period of inactivity (i.e. no touch events) To solve this issue, I have subclassed my UIWindow and implemented the sendEvent function, which allows me to get touch events on the whole application by implementing the method in one place. This works everywhere beside when the keyboard is presented and the user is typing on the keyboard. What I need to know is that is there a way to detect touch events on the keyboard, kind of like what sentEvent does for uiWindow. Thanks in advance.

found a solution to the problem. if you observe the following notifications, you are able to get an event when the key is pressed. I added these notifications in my custom uiwindow class so doing it at one place will allow me to get these touch events throughout the application.

[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyPressed:) name: UITextFieldTextDidChangeNotification object: nil];
[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyPressed:) name: UITextViewTextDidChangeNotification object: nil];

- (void)keyPressed:(NSNotification*)notification
{  [self resetIdleTimer];  }

anyways, hope it helps someone else.
