A task to compute routes and turn-by-turn directions.
Instances of this class represent a task used to compute routes and turn-by-turn directions. It allows you to find a variety of routes between any given locations - the quickest, shortest, most scenic, and so on. The route returned depends on the impedance chosen by you. For example, if the impedance is time, then the best route is the quickest route. Hence, the best route can be defined as the route that has the lowest impedance.
The task can be created for an ArcGIS Network Analyst service hosted in the cloud on ArcGIS Online or on-premises with ArcGIS Server. The task can also be created for a transportation network dataset stored locally on the device in which case it can used even when the device has no network connectivity.

Cancels loading if it is in progress, otherwise it does nothing. This should be called carefully because other objects could be waiting for loadWithCompletion:
or retryLoadWithCompletion:
to complete and this will call them all back with the error of NSUserCancelledError
- (id<AGSCancelable>) defaultRouteParametersWithCompletion: | (void(^)(AGSRouteParameters *__nullable routeParams, NSError *__nullable error)) | completion |
A convenience method to get properly initialized parameters for computing a route. The parameters are initialized with default values based on the routeTaskInfo
property.
completion | block that is invoked when the operation completes. The route parameters are populated if the operation succeeds, else the error is populated if the operation fails. |
- (void) doCancelLoading |
Never call this method directly. The framework calls this method on a background thread when cancelLoad (AGSLoadable-p)
is called. It is meant to be overriden by subclasses. Subclasses should override this method to cancel loading their data and call loadDidFinishWithError: (AGSLoadableBase(ForSubclassEyesOnly))
at the end passing in an error representing NSUserCancelledError
.
Provided by category AGSLoadableBase(ForSubclassEyesOnly).
- (void) doStartLoading: | (BOOL) | retrying |
Never call this method directly. The framework calls this method on a background thread when loadWithCompletion: (AGSLoadable-p)
or retryLoadWithCompletion: (AGSLoadable-p)
is called. It is meant to be overriden by subclasses. Subclasses should override this method to load their data and call loadDidFinishWithError: (AGSLoadableBase(ForSubclassEyesOnly))
upon completion, passing in the error if any.
retrying | flag that is true if this method was called from retryLoadWithCompletion: (AGSLoadable-p) . |
Provided by category AGSLoadableBase(ForSubclassEyesOnly).

- (void) loadDidFinishWithError: | (nullable NSError *) | error |
Only subclasses should call this method in doStartLoading: (AGSLoadableBase(ForSubclassEyesOnly))
and doCancelLoading (AGSLoadableBase(ForSubclassEyesOnly))
when done loading or failed to load.
Provided by category AGSLoadableBase(ForSubclassEyesOnly).

Loads data for the object asynchronously. The completion block is invoked upon completion.
You can call this method any number of times, however only one attempt is made to load the data. If it is already loading, it will just continue to load (i.e. not force a reload). If it has already loaded successfully, the completion block will be invoked right away. If it has already failed to load, the completion block will be invoked right away with error previously encountered. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.
completion | block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load. |
- cancelLoad
to cancel loading - retryLoadWithCompletion:
to force reload - (void) onLoadStatusChanged |
Never call this method directly. The framework calls this method on a background thread when AGSLoadable::loadStatus
changes is called. Subclasses can optionally implement this to know when their loading status has changed.
Provided by category AGSLoadableBase(ForSubclassEyesOnly).

requiredinherited |
Tries to reload when an object has failed to load. This method should be called judiciously. It should be called when:
cancelLoad
and then this methodIf the data hasn't started loading, it will start loading. If it is already loading, it will just continue to load. If it has already loaded successfully, calls back right away. If it has already failed to load, tries again. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.
completion | block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load. |
- (id<AGSCancelable>) routeParametersWithFeatureCollection: | (AGSFeatureCollection *) | featureCollection | |
completion: | (void(^)(AGSRouteParameters *__nullable routeParams, NSError *__nullable error)) | completion | |

property, and every feature in the provided feature collection is added as a stop along the desired route.

readwriterequirednonatomiccopyinherited |
The API key to access API key enabled services and resources in ArcGIS Online.
An API key is a unique key used to authorize access to specific services and resources in ArcGIS Online. It is also used to monitor access to those services. An API key is created and managed in the ArcGIS developer dashboard and is tied to a specific ArcGIS account.
In addition to setting an API key at a global level for your application using the AGSArcGISRuntimeEnvironment::APIKey
property, you can set an AGSAPIKeyResource::APIKey
property on any ArcGIS Runtime class that implements AGSAPIKeyResource
. When you set an individual AGSAPIKeyResource::APIKey
property on an AGSAPIKeyResource
it will override the default key at the global level (on the AGSArcGISRuntimeEnvironment::APIKey
property, in other words), enabling more granular usage telemetry and management for ArcGIS Online resources used by your app. Classes that expose an API key property by implementing AGSAPIKeyResource
include:
|
readwritenonatomicstronginherited |
Security credentials to access the remote resource. Only applicable if the resource is secured.
|
readnonatomicstronginherited |
The error that was encountered during the most recent load operation. Will be nil if the operation succeeded.
|
readrequirednonatomicassigninherited |
Status of the load operation.
|
readwritenonatomicstronginherited |
The AGSRequestConfiguration object which defines the behavior and policies to use when accessing the remote resource. The default will be nil. If it is nil the [AGSRequestConfiguration globalConfiguration] will be used.
|
readnonatomicstrong |
The transportation network dataset being used by this task. Will be nil
if the task is using a service instead of a local geodatabase.
|
readrequirednonatomicstronginherited |
The URL of the remote resource.
