# Modules.CoreMotion.Altimeter

Allows Titanium client applications to access CoreMotion's Altimeter APIs. Note: This API is only available in iOS 8 and later.

Availability
8.3.0

# Properties

# apiName READONLY

Availability
8.3.0
apiName :String

The name of the API that this proxy corresponds to.

The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button returns Ti.UI.Button.


# bubbleParent

Availability
8.3.0
bubbleParent :Boolean

Indicates if the proxy will bubble an event to its parent.

Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.

Default: true

# hasAltimeterPermissions

Availability
8.3.0

Returns

Type
Boolean

# isRelativeAltitudeAvailable

Availability

isRelativeAltitudeAvailable() Boolean

Returns a Boolean value indicating whether the altimeter is supported on the current device.

Returns

Type
Boolean

# isSupported DEPRECATED

Availability
8.3.0
isSupported() Boolean

DEPRECATED SINCE 8.3.0

This API is supported on IOS 8+ and this module is now targeting iOS 8 as minimum, so this method will always return true.

Returns

Type
Boolean

# removeEventListener

Availability
8.3.0
removeEventListener(name, callback) void

Removes the specified callback as an event listener for the named event.

Multiple listeners can be registered for the same event, so the callback parameter is used to determine which listener to remove.

When adding a listener, you must save a reference to the callback function in order to remove the listener later:

var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);

To remove the listener, pass in a reference to the callback function:

window.removeEventListener('click', listener);

Parameters

Name Type Description
name String

Name of the event.

callback Callback<Titanium.Event>

Callback function to remove. Must be the same function passed to addEventListener.

Returns

Type
void

# startRelativeAltitudeUpdates

Availability
8.3.0
startRelativeAltitudeUpdates([callback]) void

Starts relative altitude updates, providing data to the given handler on the given queue every few seconds. The first altitude update will be established as the reference altitude and have relative altitude 0.

Calls to start must be balanced with calls to stopRelativeAltitudeUpdates even if an error is returned to the handler.

Parameters

Name Type Description
callback Callback<CoreMotionAltimeterData>

The method to be called when there is an update.

Returns

Type
void

# stopRelativeAltitudeUpdates
