Overview

The UIAccelerometerDelegate protocol defines a single method for receiving acceleration-related data from the system. Implementation of this method is optional, but expected.

Tasks

Responding to Acceleration Events

Instance Methods

Delivers the latest acceleration data to the delegate.

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration

Parameters

The application-wide accelerometer object.

acceleration

The most recent acceleration data.

Discussion

This method is always invoked on your application’s main thread when it is in the NSDefaultRunLoopMode run loop mode.
