How to when my iOS device rotation,the game object follow to draw to move vector ?

example: look the photo, when my iphone rotation tendency on the left , and then the object move draw to left. when iphone rotation tendency on the right , the object move to right .

How can UDK Mobile detect iOS device move or rotation , extend what .uc function??

thx very much ^_^ I will to read . thank again...

ok , I use about 2hours to read the doc.

Blade[UG]
the doc only teach about create stick kind input / buttom kind input / touch object input ...
but no any detect iOS device rotation function , example , you shake the iPhone , the object ball will shake , when you rotation the iPhone , the ball will roll .
the doc no any same input .

ummmmm... I think UDK Mobile can't to do detecting iOS rotation .

MobilePitch - The current tilt value of the device's gyroscope, if available.
MobilePitchCenter - The center value for the device pitch.
MobilePitchMultiplier - Scaling factor for the device's pitch, adjusting sensitivity to pitch motion.
MobileYaw - The current yaw value of the device's gyroscope, if available.
MobileYawCenter - The center value for the device yaw.
MobileYawMultiplier - Scaling factor for the device's yaw, adjusting sensitivity to yaw motion.
MobilePitchDeadzoneSize - The distance from the MobilePitchCenter that the MobilePitch value must be to be considered for input. This would be used if motion input was being used for controls in the game.
MobileYawDeadzoneSize - The distance from the MobileYawCenter that the MobileYaw value must be to be considered for input. This would be used if motion input was being used for controls in the game.
DeviceMotionAttitude - A Vector describing the attitude or orientation of the device.
X - Represents rotation around the axis coming straight out from the screen.
Y - Only valid if the device has a gyroscope.
Z - Represents rotation around the horizontal axis of the device.
DeviceMotionRotationRate - A Vector holding the rate of change of the device's attitude. This value is much more accurate on devices with a gyroscope.
DeviceMotionGravity - A Vector holding the gravity vector of the device. Only valid if the device has a gyroscope.
DeviceMotionAcceleration - A Vector holding the current linear acceleration of the device. Only valid if the device has a gyroscope.
bDeviceHasGyroscope - TRUE if device has a gyroscope.
DeviceGyroRawData - A Vector holding the raw gyroscope motion data. Values are in the range [0.0, 1.0].
bDeviceHasAccelerometer - TRUE if device has an accelerometer.
DeviceAccelerometerRawData - A Vector holding the raw accelerometer data. Values are in the range [0.0, 1.0].
X - Roll. Represents rotation around the axis coming straight out from the screen.
Y - Portrait Pitch. Represents rotation around the horizontal axis in portrait orientation.
Z - Lanscap Pitch. Represnts the rotation around the horizontal axis in landscape orientation.
MobileSeqEventHandlers - An array of SeqEvent_MobileBase events looking to listen in on Motion events.
