PointAnnotationManager overlap settings not working about mapbox-maps-ios HOT 4 OPEN

Hi @bricepollock, thank you for writing in, by default PointAnnotationManager allows are icons and texts to be overlapping, this explains why you disable both textAllowOverlap and iconAllowOverlap but the annotations are still overlapping.

You can take a look at Label collision and let us know if it helps you achieve what you want. Additionally you can enable map's debugOptions as shown below to see how the annotations are overlapping

mapView.debugOptions = [.collision]

from mapbox-maps-ios.

My goal was to have text hidden when overlapping any part of another PointAnnotation, but always show the image.

@bricepollock Try this configuration:

manager.textAllowOverlap = false
manager.iconAllowOverlap = true
manager.textIgnorePlacement = false
manager.iconIgnorePlacement = false
manager.textOptional = true

from mapbox-maps-ios.

@persidskiy this is much closer to what I was going for, thank you! It wasn't clear that the placement properties were important since the Label Collision appeared to only reference map-elements as 'other symbols' in placement description.

Your config provided hidden text if it collides with other text. However, ideally, I want the text to be hidden whether it collides with either icon or text (like how MapKit works). Turning on iconAllowOverlap hides annotations for icon-collisions, which isn't the optionalText behavior I'm looking for. Avoiding overlaps would result in a lot cleaner map. Is there a way to configure 'hide text if collides with icon or text' or a mechanism to manage collision-hiding behavior for PointAnnotations manually?

Example of overlap:

@persidskiy @maios would love any more details on collisions if you have some
