nsevent

Hi I am working on an iphone application and want to handle keyboard events in iphone. In Mac, there is a class NSEvent which handles both keyboard and mouse events, and in ios (iphone/ipad) the counterpart of NSEvent is UIEvent which handles only touch events. I know ios API does not provide this functionality, but how can i handle key events in iphone??? Any good tutorial or sth, to get started... You cant directly code for keyboad;s key and there is no mouse in case of device. you can make your logics for different kind of charectersets or you can make your logics in textField delgate

In my application, I want the scrolling to happen, only with scroll wheel action from a mouse and not from the two finger gesture on a trackpad. Basically, I am trying to determine if the scrollWheelEvent is generated from the mouse or trackpad, inside - (void)scrollWheel:(NSEvent *)theEvent method. From what I know so far, it seems like there is no straightforward way to accomplish this. I tried a work around of setting a boolean variable to true and false inside -(void)beginGestureWithEvent:(NSEvent *)event; and -(void)endGestureWithEvent:(NSEvent *)event; But this is not a solution because

I just experimented with the addLocalMonitorForEventsMatchingMask:handler: method in NSEvent and came across the following question: How do I find out if only certain modifiers were pressed? A short example to set this question into context: I wanted to listen for the shortcut "⌘+W". Therefore I wrote the following code: [NSEvent addLocalMonitorForEventsMatchingMask:NSKeyDownMask handler:^(NSEvent *theEvent) { if ([theEvent modifierFlags] & NSCommandKeyMask && [theEvent keyCode] == 13) { [self.window performClose:self]; } return theEvent; }]; This works well, however the shortcut will be

I was wondering if NSEvent responds to the "Shift" key on the keyboard. I am logging the keyCodes when debugging my app and I don't get a keyCode value for the shift key. Thanks, Kevin EDIT: This is the code I am using from a user response. -(void)keyDown:(NSEvent*)event { if ([event modifierFlags] == NSShiftKeyMask) { NSLog(@"Shift key pressed"); } } The Shift key is still not being recognized... Take a look at the flagsChanged: method of NSResponder . Something like this: - (void) flagsChanged:(NSEvent *) event { if ([event modifierFlags] & NSShiftKeyMask) { //Do something } } Your code

I'm trying to create an OS X keyboard hook for assistive technology purposes (i.e. don't worry, not a keylogger). When a user presses a key, I want to prevent the real keypress and send a fake keypress (character of my choosing) instead. I have the following code: - (void) hookTheKeyboard { CGEventMask keyboardMask = CGEventMaskBit(kCGEventKeyDown); id eventHandler = [NSEvent addGlobalMonitorForEventsMatchingMask:keyboardMask handler:^(NSEvent *keyboardEvent) { NSLog(@"keyDown: %c", [[keyboardEvent characters] characterAtIndex:0]); //Want to: Stop the keyboard input //Want to: Send another key
