# stopRelativeAltitudeUpdates()

Stops the delivery of relative altitude data for the altimeter object.

## Declaration

```swift
func stopRelativeAltitudeUpdates()
```

## Discussion

Discussion Calling this method ends the delivery of relative altitude events and releases the references to the operation queue and block that you specified in the startRelativeAltitudeUpdates(to:withHandler:) method. If you haven’t started delivering data, or if you’ve already called stopRelativeAltitudeUpdates(), this method does nothing.
