# CMSensorDataList

A list of the accelerometer data recorded by the system.

## Declaration

```swift
class CMSensorDataList
```

## Overview

Overview You do not create instances of this class directly. Instead, you receive one as the result of a query for accelerometer data from a CMSensorRecorder object. You use a sensor data list object to enumerate over the accelerometer data as shown in the following example: -(void)processSamplesFromDate:(NSDate*)start toDate:(NSDate)end {    CMSensorRecorder* recorder = [[CMSensorRecorder alloc] init];    CMSensorDataList* list = [recorder accelerometerDataFrom:start to:end];      for (CMRecordedAccelerometerData* data in list) {       // Process the data.       NSLog(@"Sample: (%f, %f, %f)", data.acceleration.x,               data.acceleration.y, data.acceleration.z);    } }
