react-native-maps custom map style

Asked 2022-Mar-23 at 17:44

I created a json using google maps styling wizard. I then set that to a const under render and set that const to my MapView style but it renderers nothing when I do.

I am not sure the issue, Ideally I would like to have the style in a separate file but I was trying to start small.

How can I fix the current issue I am having as well as import and use the style from a separate file?

Here is a snack of my code that reproduces my exact error as well as the code below.

The custom google maps styling must be passed to the customMapStyle prop and you need to set a specific width and height in the normal style prop of the MapView. Setting absoluteFillObject does something different than you might have thought and according to the react-native documentation there is

Currently, there is no difference between using absoluteFill vs. absoluteFillObject.

Thus, absoluteFill is for the following use case.

A very common pattern is to create overlays with position absolute and zero positioning (position: 'absolute', left: 0, right: 0, top: 0, bottom: 0), so absoluteFill can be used for convenience and to reduce duplication of these repeated styles.

This will not set a height and a width! We need to do this manually which is documented here.

The following solves your problem.

Okay so I finally got it thanks to this tutorial:

https://www.raywenderlich.com/9956648-mapkit-tutorial-overlay-views#toc-anchor-003

I'll try to do my best to explain everything here the best I can, I copied a bunch of the code from Ray's website so I don't understand everything 100%. That being said, the main meat of what needs to be done is to layout the coordinates for the overlay. This was done in a custom class. The idea here is to parse coordinate data which was written in a plist in a Dictionary. For my project this was easy because I simply had to set the maximum coordinates for the Earth ((90, 180), (90, -180), (-90, -180), (-90, 180)). The mid coordinate only worked when I set it as (100, 0), not sure why, but the full code for parsing the plist is below.

As a follow-up to your comment, I have prepared a reprex so that you can test the code. It should work...

If it doesn't work, here are some suggestions:

Make sure all your libraries are up to date, especially tidyverse, mapview and sf. On my side, I run the code with the following versions: tidyverse 1.3.1, mapview 2.10.0 and sf 1.0.6
Close all open documents in your R session and close R. Reopen a new R session and open only the file that contains the code to test.
Load only the libraries needed to run the code.

Hope this helps. I'm crossing my fingers that these suggestions will unstuck you.

iOS MapKit - Which overlay was tapped

Asked 2022-Mar-04 at 09:24

I am trying to build an app that shows some areas(polygons/overlays) on the map and when a polygon is tapped I would like to print on console print("Polygon \(zone_id) has been tapped"). The polygons are rendered from a GeoJSON file where we can also find the zone_id in the properties feature. So far I rendered the overlays on the map but I am stuck and I appreciate some guidance where to go from here.

I will paste my code that I have so far and also a snippet of the GeoJSON file.

...

ANSWER

Answered 2022-Mar-04 at 09:24

Ok, I found a solution if anyone else will ever need it.

I added a UITapGestureRecognizer to my map view instance.
I used the MKMapView's convert(_:toCoordinateFrom:) to convert the touch point to the map coordinates
I created a MKMapPoint from that coordinate and checked if the MKPolygon renderer path contains the point
For the MKPolygon, being a MKShape after all, I used the .title property to assign my zone_id value parsed from the GeoJSON.

So I was able to identify which polygon was tapped.

How to create maps based on conditional panel in R with Shiny?

Asked 2022-Feb-25 at 22:47

I am trying to create several leaflet maps based on what the user select. I tried to produce a reproducible example. I have a sf with four shapes (i.e., representing four counties in NC). The user can choose to plot one to four maps based on the choice of the county (made through the "checkboxGroupInput". If the user select one county, I should plot one map representing the county the user selected. If the user selected two counties, two maps should be plotted, etc.

I got several lines of code but I could not connect the user selection to my map. Below you can find what I tried to do. Thanks for any help.

ANSWER

Answered 2022-Feb-25 at 22:47

Interesting question. I would use a rather different approach to get the job done. Instead of creatign that many conditional panels, I would write a function that creates a collection of columns depending on the number of counties selected.

I don't know if you are reading this, but you have forgotten to include ON_START event for lifecycle, so you are throwing the exception. Also you are calling onStart on ON_CREATE.

Also consider populating the lifecycleObserver to be scoped into the DisposableEffect and make the DisposableEffect also aware of the mapView (give it as an argument).
