pressure

Are there any scale on the touch inputs? I know there is sensibility settings to say if you touch or not, but does it has a scale for hard pressure and low pressure too? If so, what scale is it? 0 to 1 or 0-255 or what possiblities? Well, that entirely depends on the API. Android, for example, has a getPressure() accessor in MotionEvents that returns a float between 0.0f and 1.0f, but the actual granularity of your result obviously depends on the hardware - if the screen can only detect "pressed" vs "non-pressed", you will only ever get 0.0f or 1.0f. EDIT: As per Julio Gorgé's answer, iOS does

it's working great with one UIButton: – (void) viewDidLoad { [super viewDidLoad]; CPBPressureTouchGestureRecognizer* recognizer = [[CPBPressureTouchGestureRecognizer alloc] initWithTarget:self action:@selector(A_button:)]; [A_button addGestureRecognizer: recognizer]; [recognizer release]; } - (void) A_button: (CPBPressureTouchGestureRecognizer*) recognizer { [pan_A setGain:recognizer.pressure]; [pan_A] play; } i tried to use more but only the second one is working: - (void) viewDidLoad { [super viewDidLoad]; CPBPressureTouchGestureRecognizer* recognizer1 = [[CPBPressureTouchGestureRecognizer

I want to find the pressure of the touch. I just don't know how to accomplish that result with out jailbreaking it and getting the raw touch data. Does anyone know How I would do this? You cannot get the pressure from the SDK nor undocumented methods. However you can detect the size of touch with undocumented methods. In the GSEvent, which is a lower-level representation of UIEvent, there is a structure known as GSPathInfo with members: typedef struct GSPathInfo { unsigned char pathIndex; // 0x0 = 0x5C unsigned char pathIdentity; // 0x1 = 0x5D unsigned char pathProximity; // 0x2 = 0x5E CGFloat
