iOS

hi,

i'm new to iOS developing and i'm currently using the 4.x beta.

i'm trying to make a ball driven by the gyro of the iPhone.

i've no success until there. tried to find tutos and so but nothing seems to help me.

i've downloaded the "Roll-a-Ball.zip" project on unity website but, once launched on my iPhone, the ball doesn't react normally.

is there known problems with iOS library in unity 4 ?

if there's any good tut on the subject that would be more than welcome

thanks
