I've calculated the velocity from the acceleration of UIAcceleometer, and I want to move the UIView in opposite of the distance which the device moves but same distance. For example, if I move the device to right, the UIView should go left with the same distance on screen.

The problem is that the UIAcceleration shows the G value, I can only convert it to meter. How can I transform the meter value to local coordinate on screen?

Thanks a lot!

  • I don't think that feature is implemented in iOS. It'll be trial & error tens of times over and over again until you find the correct relationship between G and point (don't use pixels). – Constantino Tsarouhas Aug 18 '11 at 10:06
