A base class for all views that can display geographic content on screen.
A base class for all views that can display geographic content on screen. Subclasses can display the content in either 2D (AGSMapView
) or 3D (AGSSceneView
). In an MVC architecture, this class and its subclasses represent the View tier. The Model tier is represented by the geographic content which could be a map (AGSMap
) or scene (AGSScene
).

|
readnonatomiccopy |
Attribution for the geographic data currently being displayed in the view. This information is displayed in a banner along the bottom edge of the view. The attribution text changes can be monitored using Key-Value Observing (KVO).
|
readwritenonatomicassign |
Specifies whether the attribution text banner (along the bottom edge of the view) should be visible. Defaults to YES
.
|
readnonatomicstrong |
The NSLayoutAnchor
you can use to layout views in relationship to the attribution text on the AGSGeoView
. This is helpful if you want to place a view just above the attribution text. And when the attribution text is collapsed or expanded your view will automatically move to the correct location in relation to the attribution text.
|
readnonatomicstrong |
A callout view for displaying information on the map.
|
readnonatomicassign |
Current drawing status of the view's content (map or scene). The draw status changes can be monitored using Key-Value Observing (KVO).
|
readnonatomicstrong |
A list of AGSGraphicsOverlay
objects that can be used to display graphics on top of the view's content.
|
readwritenonatomicstrong |
The view label properties.
The view label properties are an overall control for whether labels will be created and displayed for layers added to the view. Individual layers can also control whether labels should be displayed for their features. Labels need to be enabled both in the view and in the layer. By default the labeling for a view is enabled. The view label properties also control global aspects of the label appearance e.g. animation effects.
AGSViewLabelProperties
|
readwritenonatomiccopy |
Block that is invoked whenever any map or scene layer's view state changes.
|
readnonatomicassign |
Specifies whether the view is navigating, for example, when a pan or zoom animation is in progress or if a user is interacting with the view by dragging or pinching. The navigating changes can be monitored using Key-Value Observing (KVO).
|
readwritenonatomicassign |
|
readwritenonatomicstrong |
The selection properties that is applied to the geo view.
This property allows configuration of new selection highlighting functionality such as selection promotion and switchable selection halo.
Notes on per-layer selection coloring (supported in 2D only):
The deprecated per-layer selection coloring functionality is initially enabled.
If the AGSGeoView's
AGSSelectionProperties
are touched, per-layer selection coloring is then disabled for the lifetime of the view. (Here, 'touched' means replacing the view's AGSSelectionProperties
, or calling a setter property on the view's AGSSelectionProperties
).
Use of per-layer selection coloring is deprecated and may have a detrimental impact on rendering performance.
When per-layer coloring is enabled and more than one selection color is configured, selection halo will be disabled.
To enable selection halo or promotion, set the properties to YES
. Again, this will automatically disable per-layer selection coloring for the lifetime of the view.
|
readnonatomicstrong |
Spatial reference defining the coordinate system in which the view's content is displayed. The spatial reference changes can be monitored using Key-Value Observing (KVO).
|
readwritenonatomicstrong |
The current AGSTimeExtent
of the AGSGeoView
. The Time Extent of the AGSGeoView
defines how time-enabled data is displayed. Participating layers filter their data to only show data within the time extent set on the AGSGeoView
(see AGSTimeAware
for details). The range of the time extent includes the start and end values (a feature at 10/24/2016 would be included in a time extent defined as 10/24/2016 - 11/14/2016). Time filtering is not enabled until a non-nil time extent is set on the AGSGeoView
. When the time extent is nil
on the GeoView, no time filtering is applied and all content is rendered. The time extent changes can be monitored using Key-Value Observing (KVO).
AGSTimeAware::timeFilteringEnabled
property to see if time filtering is enabled on layers.
|
readwritenonatomicweak |
Delegate to be notified when touch events occur on the map.The delegate class must adopt the AGSGeoViewTouchDelegate
protocol.
|
readwritenonatomiccopy |
Block that gets invoked whenever the viewpoint changes.
|
readnonatomicassign |
Specifies whether the view's content wraps around the dateline.
