Sizing UIButton depending on length of titleLabel

Asked 2021-Oct-29 at 21:51

So I have a UIButton and I'm setting the title in it to a string that is dynamic in length. I want the width of the titleLabel to be half of the screen width. I've tried using .sizeToFit() but this causes the button to use the CGSize before the constraint was applied to the titleLabel. I tried using .sizeThatFits(button.titleLabel?.intrinsicContentSize) but this also didn't work. I think the important functions below are the init() & presentCallout(), but I'm showing the entire class just for a more complete understanding. The class I'm playing with looks like:

The UIButton class owns the titleLabel and is going to position and set the constraints on that label itself. More likely than not you are going to have to create a subclass of UIButton and override its "updateConstraints" method to position the titleLabel where you want it to go.

Your code should probably not be basing the size of the button off the size of the screen. It might set the size of off some other view in your hierarchy that happens to be the size of the screen but grabbing the screen bounds in the middle of setting a view's size is unusual.

As also answered here, clCreateCommandQueueWithProperties is an OpenCL 2.0 thing. Nvidia GPUs only support OpenCL 1.2. Nvidia recently "upgraded" to OpenCL version 3.0, but this is just a new name for version 1.2. OpenCL 2.0 features are still not supported.

Mapbox compile offline tool on Linux

Asked 2021-May-26 at 10:15

I am trying to compile the Mapbox GL offline tool (mbgl-offline) on Linux to generate a database with offline data for a specific region.

Steps followed as posted in github repository to compile the offline tool on Linux but it failed:

git clone --recurse-submodules https://github.com/mapbox/mapbox-gl-native.git
cd mapbox-gl-native
make offline (i tried also make mbgl-offline)
compilation failed: Error message: make: *** No rule to make target 'offline'. Stop.

Any idea what is going wrong with compilation of the tool ?

The README.md clearly states how to build Mapbox: Developing

You tried to compile it with make, but if you look around the repository there are a lot of CMakeLists.txt, which indicates that you should use CMake to compile it.

These are the steps I followed to build it:

Mapbox in Android - Black color around GEOTiff raster layers

Asked 2020-May-28 at 14:11

Goal

I need to add some aeronautical layers taken from FAA to the map. The layers are provided as GeoTIFF files.

Steps

Downloaded a GeoTiff file from FAA website.
Using QGis app clipped the legend from the file. Actually the issue occurs without this step as well.
Reprojected it to EPSG:3857 using GDAL command gdalwarp -q -t_srs EPSG:3857 -dstalpha -of vrt Albuquerque\ SEC\ 104-cut.tif /vsistdout/ | gdal_translate -co compress=lzw /vsistdin/ Albuquerque\ SEC\ 104-north-up-cut.tif. Otherwise I got Error creating Mapnik Datasource: Invalid raster: Invalid rotation value in geotransform array when uploading to Mapbox.
Created a Tileset by uploading GeoTIFFs to Mapbox.
Created a new style in the Mapbox Studio.
Added the tilesets as layers.

Mapbox Studio Result

The map is showing well in Mapbox Studio:

Android Result

However in Android app this style shows with some black borders of random width depending on zoom level and camera position. Here is how it looks in android:

I tried it on Pixel 3a (Android 10), Nexus 5x (Android 8.1) and Android emulator (Android 10). I have good internet connection and gave it enough time so the tiles are loaded.

The source code where the map is embedded is official Demo app. I just replaced token and style URL:

ANSWER

Answered 2020-May-28 at 14:11

The black borders should be transparent, but the raster image format Mapbox is using (JPG) does not support transparency, which is a known issue that exists in every gl-native-based SDK. This issue presents itself when you reference a style that has the raster layer built in.

As a workaround, you can follow Mapbox's troubleshooting guide on troubleshooting raster images with black backgrounds to make your tileset transparent and then add the tileset as a RasterSource within your Android application to display the raster tile as expected.

Please take a look at the following example as a reference for adding a RasterSource:

Add a WMS Source

Instead of calling the rasterSource using "mapbox://username.tilesetID", you need to call it similarly to the Add a WMS Source example. The code below will resolve your issue:

style.addSource(RasterSource( "albuquerque-source", TileSet( "tileset", "https://api.mapbox.com/v4//{z}/{x}/{y}.png?access_token=" ), 256 ))

QUESTION

Convert mbgl-offline db to mbtiles

Asked 2020-Apr-09 at 10:13

I'm trying to implement mapbox offline in my flutter application... until now I'm using the repository https://github.com/mapbox/mapbox-gl-native to get the map but this map comes in format *.db which is a SQLite format.

Now if I want to use that map (in format .db) in flutter I found the package https://github.com/tobrun/flutter-mapbox-gl where it has an instructions for loading the map (.db) ...

Now, that library is so basic .. I can't do more things like put markers or anything else.. that's why I'm trying to use the other library which is more common in fluter and is called 'flutter_map' and it has a way to load offline maps but the problem here is that I need '{x}{y}{z}.png' that's an image format.

Finally my question is: How can I pass from my map (.db) to that format ({x}{y}{z}.png) ??? or maybe ... how to convert (.db) to (*.mbtiles) ?? cause the last one is more common.

Thanks again!

ANSWER

Answered 2020-Apr-09 at 10:13

Mapbox offers the Raster Tiles API which will serve map tiles in ({x}{y}{z}.png) format. https://docs.mapbox.com/api/maps/#raster-tiles These images will be satellite imagery though.

Mapbox also offers the Vector Tiles API which serves map tiles in .mvt format. https://docs.mapbox.com/api/maps/#vector-tiles

Conversion to .mbtiles

You can convert .mvt tiles to geoJSON using this converter.
Use Mapbox Tippecanoe to convert from geoJSON to .mbtiles

I check the mapbox-gl-native module and I found it's powered by vector tiles and OpenGL. Here is the problem, you will not be able to usethis module due to the GDI sandbox restrictions (GDI - which openGL relies on).

That YouTube video you're following is a bit old. Setting up a simple MapView is now done differently. For example, you can't set a map style URL via XML anymore.

https://docs.mapbox.com/android/maps/examples/create-a-simple-map-view shows the basic way to set up a Mapbox map.
