MapBox and HERE ok on OSX but not working on IOS

AddTheBadd

Hello, I have an application that displays a map with a Polyline overlay and the application builds and works as expected on OSX. When I build and deploy on IOS the application works and I get no new error messages but the map is simply blank. This happens whether I use MapBox or HERE. I was originally using MapQuest before the license change and MapQuest worked on IOS and OSX. I am using Qt 5.7.0 and QtLocation 5.6. I have included below some code extracts. I generate the Map in C++ then use the createMap() function to inject the code into the QML. The code is for MapBox but I have a HERE version which does the same thing. Any Help would be greatly appreciated. With no error message I'm not sure where to start!

import QtLocation 5.6;
Map { anchors.fill: parent; plugin: mapBoxPlugin; MapPolyline { line.width: 3; line.color: 'green'; path: [ { longitude: -4.93616, latitude: 54.4058, altitude: 6123.53 }, { longitude: -4.93287, latitude: 54.4049, altitude: 6127.04 }, 
{ longitude: -4.92937, latitude: 54.4039, altitude: 6129.64 }, { longitude: -4.92621, latitude: 54.4029, altitude: 6130.84 }, { longitude: -4.92267, latitude: 54.4019, altitude: 6132.23 }, { longitude: -4.91917, latitude: 54.4009, altitude: 6134.3 }, { lon

9023, latitude: 54.396, altitude: 6148.65 }, { longitude: -4.89884, latitude: 54.395, altitude: 6151.95 }, { longitude: -4.89591, latitude: 54.3942, altitude: 6154.82 }, { longitude: -4.89323, latitude: 54.3934, altitude: 6157.52 }, { longitude: -4.88997, latitude: 54.3925, altitude: 6160.79 }]; } MapPolyline { line.width: 7; line.color: 'orange'; path: [ ]; } }

function createMap(map) {
	var newObject = Qt.createQmlObject( map, eventMap, "dynamicMap");
	newObject. fitViewportToMapItems();
	return "eventMap - Done It!";
}

Plugin {
	id: mapBoxPlugin
	name: "mapbox"
	PluginParameter { name: "mapbox.access_token"; value: "pk.RemovedActualToken!" }
	PluginParameter { name: "mapbox.map_id"; value: "mapbox.run-bike-hike" }
}

You should register to mapbox and then take a real token for your app.

AddTheBadd

Thank you Nick. I do have a real Token and as I mentioned in my post the code works correctly in OSX. I just removed the real Token from the code.

NickV

Then you should see the permissions of the ios.

AddTheBadd

How do I see the permissions of the ios? Do you know what permissions I need to check?

NickV

You can see it using xcode. I don't know the exact permission of the ios. You could try using this:

Plugin{
id:myPlugin
name: "mapbox"
PluginParameter{
name: "mapbox.map_id";
value: "mapbox.streets"
}
PluginParameter{
name: "mapbox.access_token";
value: " your token"
}
}
As You can see the only difference is map id. Try it.

AddTheBadd

I have just tried using mapbox.streets as the map_id. As before it works on OSX but gives me nothing on IOS. I get no error messages, no map tiles and no path.

Hi AddTheBadd,
did you find a solution for your problem? Same here, using the google plugin from vladest works perfect on android but under ios nothing is displayed and no error message :(
best,

I had the same problem, but adding the following to the project's .pro file fixed the issue:
QT += qml quick positioning sensors location network

I had no errors before so no idea what was happening, but seems like just for iOS these are explicitly needed for the map plugin to work properly.
