I just wanted to know that the value of parameter x,y,z which that is using for subtracting filtered value.

I mean in code..

if (z – accelerationArray[Z_DIR] > 0.5 || z – accelerationArray[Z_DIR] < -0.5)
{
…
}

what is value of z.
same for x and y.

Thank you in advance

Is it good practice to set the delegate back and forth between nil and self repeatedly if you’re starting and stopping accelerometer data collection, or should you turn it on once and then turn it off when the view disappears etc.?

this is awesome

before i not delegate to nil my app will crashing and while i assign nil to delegate it work fine thanks buddy. great post keep it up…….

Could you please help any one how we got it using acceleration values?

Example:- Suppose we move Device like a (Frisbee Throw)? How we can get this motion occur in Device.

i am using (UIAccelerometerDelegate). my problem is how we distinguished between different-2 device motion.

For example we have moved device like a frisbee, and we get x, y, z data in acceleration.

How we calibrate these data for identifying motion?

One idea take some sample motion data in x, y, z as a standard for particular motion and compare it.

But every time we got different data and it’s not possible to how to compare these data?

Please help me….

it would be more clear to write 1.0/25.0, and a good practice, however, the conversion to a double will be done for you.
