How to change the appearance of different states
The MapsIndoors iOS SDK supports Select and Highlight Display Rules and they can be retrieved and edited through MPMapsIndoors.shared.
Example
// Changing the visibility of a polygon for selection
if let displayRule = MPMapsIndoors.shared.displayRuleFor(displayRuleType: .selection) {
displayRule.polygonVisible = true
}
// Changing the visibility of a label for highlights
if let displayRule = MPMapsIndoors.shared.displayRuleFor(displayRuleType: .highlight) {
displayRule.labelVisible = false
}
Highlight
Highlight all Restrooms
// Create a filter to only receive locations with the category Toilet
let filter = MPFilter()
filter.categories = ["Toilet"]
// Query locations with the created filter
let locations = await MPMapsIndoors.shared.locationsWith(query: nil, filter: filter)
// Highlighting all current toilets, with the default MPHighlightBehavior.
// The MPHighlightBehavior can be used to customize the camera and map behavior,
// like fitting the view to show all highlighted locations.
mapControl?.setHighlight(locations: locations, behavior: .default)
Clear the highlight
mapControl?.clearHighlight()
Styling the Highlight Badge
Example: Change the color of the Highlight Badge
if let highlightRule = MPMapsIndoors.shared.displayRuleFor(displayRuleType: .highlight) {
highlightRule.badgeFillColor = .blue
highlightRule.badgeStrokeColor = .red
}
mapControl?.setHighlight(locations: [loc], behavior: .default)
Example: Hide the Highlight Badge
if let highlightRule = MPMapsIndoors.shared.displayRuleFor(displayRuleType: .highlight) {
highlightRule.badgeVisible = false
}
mapControl?.setHighlight(locations: [loc], behavior: .default)
You can easily change the icon to an image from your app Asset Catalogue. In this example it is assumed that you have an image in the project Asset Catalogue named selectionIcon:
if let selectionRule = MPMapsIndoors.shared.displayRuleFor(displayRuleType: .selection) {
selectionRule.icon = UIImage(named: "selectionIcon")
}
mapControl?.select(location: loc, behavior: .default)
Deprecated Selection Highlight
Before the release of 4.3.0 the MapsIndoors SDK already had a visual implementation of selection with a Display Rule. That Display Rule can also be changed like the newly introduced Selection Display Rule. If you want to retain the old selection rendering, it can be toggled through the Solution Config on the SDK.
Note that the newSelection setting lives on the Solution, so with any subsequent load of MapsIndoors it will be necessary to set the value to false again, as it defaults to true.
The new Highlight Display Rule has a collection of new properties that can be used to change the style of the Highlight badge. You can see all current Display Rule properties in .
The selection Display Rule is for changing the appearance of single selected Location, for example when the user clicks on it. To select a Location programmatically, call the method
