ArcGIS Runtime SDK for iOS: AGSSubtypeFeatureLayer Class Reference
ArcGIS Runtime SDK for iOS  100.12
AGSSubtypeFeatureLayer Class Reference

Description

A layer that can visualize feature data with different visibility, rendering, popup properties, and so on for some or all of the subtypes in an AGSArcGISFeatureTable.

The AGSArcGISFeatureTable must have an AGSArcGISFeatureLayerInfo::subtypeField and at least one AGSFeatureSubtype defined, otherwise the layer will fail to load.

Subtypes provide a way to organize your data within an ArcGIS feature table. For example, the streets in a city streets feature table could be categorized into three subtypes - local streets, collector streets, and arterial streets. The benefit of the subtype feature layer is that it allows you to configure different layer properties per subtype. This is particularly useful for data, such as utility networks, in which many different network elements are grouped into a single subtype feature layer.

Functional characteristics:

The subtype feature layer acts like a group layer that automatically creates one feature layer, or subtype sublayer, for each subtype in the table. Each subtype sublayer can be configured independently of one another. They can have different renderers, label definitions, max and min scales, visibility, layer order in the map, and so on. When a subtype group layer is read from a web map or mobile map, it is represented as an AGSSubtypeFeatureLayer object. Saving a map that contains an AGSSubtypeFeatureLayer object will save the layer as a subtype group layer. Subtype feature layers are supported in offline maps and will work in offline editing workflows.

Performance characteristics:

Queries are optimized across all sublayers. For example, a pan of the map sends a single request to the feature table to cover all the sublayers. If you had manually created a feature layer for each subtype, this would have resulted in one query per feature layer.

Method Documentation

◆ cancelLoad

- (void) cancelLoad
requiredinherited

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

Since
100

◆ clearSelection

- (void) clearSelection

Clears selection on all features.

Since
100

◆ doCancelLoading

- (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.

Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

◆ doStartLoading:

- (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.

Parameters
retryingflag that is true if this method was called from retryLoadWithCompletion: (AGSLoadable-p).
Since
100

◆ loadDidFinishWithError:

Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

◆ loadWithCompletion:

- (void) loadWithCompletion: (nullable void(^)(NSError *__nullable error))  completion
requiredinherited

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.

Parameters
completionblock that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load.
Note
The completion block is always invoked on the main thread.
Since
100
See also
- cancelLoad to cancel loading
- retryLoadWithCompletion: to force reload

◆ onLoadStatusChanged

- (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.

Since
100

Provided by category AGSLoadableBase(ForSubclassEyesOnly).

◆ resetFeaturesVisible

- (void) resetFeaturesVisible

Reset the visibility of all features back to their original state.

Since
100

◆ resetRenderer

- (void) resetRenderer

Reset the renderer back to the original renderer provided by the featureTable. This is useful if you, for instance, change the renderer and then want to revert back to the original.

Since
100

◆ retryLoadWithCompletion:

- (void) retryLoadWithCompletion: (nullable void(^)(NSError *__nullable error))  completion
requiredinherited

Tries to reload when an object has failed to load. This method should be called judiciously. It should be called when:

  1. you didn't have network connectivity earlier when it failed and you want to retry now that you have connectivity
  2. the server was down earlier when it failed and you want to retry
  3. the request is taking too long and you want to cancel it and retry, in which case you will first call cancelLoad and then this method

If 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.

Parameters
completionblock that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load.
Note
The completion block is always invoked on the main thread.
Since
100

See also
AGSLoadSettings to specify rendering mode for all feature layers in a map or scene.

◆ scaleSymbols
