bug annotation

[jeromehanse]

Hello,

I try to add annotations on my mapView, but it doesn't work.
Here the simple code : http://pastebin.com/hjFfCaZE
Error : "nil argument" ... Ok but what argument?

Do you have any idea how to resolve this?

Thanks!

I know it's an old thread, but I got the same problem.
My code:

        var Map = require('com.polancomedia.mapbox');

        var mapFile = Titanium.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory, 'custom-world-6.mbtiles');
        Ti.App.Map = Map.createView({
            map: mapFile,
            minZoom: 0,
            maxZoom: 6,
            zoom: 2,
            accessToken: 'xxxxx', //REQUIRED!!!
            centerLatLng: [37.322831,7.490234],
            width: Ti.UI.FILL,
            height: Ti.UI.FILL,
            hideAttributes: true,
            userLocation: true
        });

        var a1 = Map.createAnnotation({
            latitude: 18.467354,
            longitude: -91.903534,
            title: "Test Title",
            subtitle: "Subtitle"
        });
        Ti.App.Map.addAnnotation(a1); // Crashes here

With the following error code when adding a annotation:

*** -[__NSCFConstantString stringByAppendingString:]: nil argument

Using Titanium SDK 5.3.1.GA and iOS 9.3

@ilker55 I've come across the same issue.
I used
Ti.App.Map.addAnnotations([a1]);
Although that solved the crash issue for me but I couldn't add any annotations on the map!
Any ways, try it out and tell me if it works.

@Abdelalim-dev When I use addAnnotations I get:
undefined is not a function (evaluating 'Ti.App.Map.addAnnotations([ a1 ])')
And I don't see addAnnotations anywhere in the documentation (https://github.com/adampax/titanium-mapbox/wiki/Annotations).

To be on the same page make sure you are using the same map module I'm using (ti.map).
You can check for the latest releases here (https://github.com/appcelerator-modules/ti.map/releases)

To solve the issue of annotations not showing on the map (Android) I used a custom view instead of a simple image like so:

if (OS_IOS) {
    annotation.image = image, //your image goes here
    annotation.canShowCallout = false;
} else {
    annotation.customView = Ti.UI.createLabel({
        width : 44,
        height : 56,
        backgroundImage : image,//your image goes here
    });
}

You can then add the annotation to the map.

But i'm using the map-box module (com.polancomedia.mapbox) so ti.map annotations don't work.
