iOS: CallbackObject is not a function

[tomgiessel]

Hi there,

I've recently noticed some crashes using the TiMap module, that I can't explain and I am also unable to reproduce on any of my devices or simulators.
The JavaScript exception is CallbackObject is not a function (near '...Map.createAnnotation...') and here is the code that causes it:

try {

    // create map annotation
    var mapAnnotation = Map.createAnnotation({
        latitude  : 52.51496980,
        longitude : 13.39258080,
        title     : "my title",
        subtitle  : "my subtitle",
        pincolor  : Map.ANNOTATION_RED,
        draggable : false,
    });

    // create the map view
    // and add the annotation
    var mapView = Map.createView({
        mapType : Map.NORMAL_TYPE,
        region  : {
            latitude       : 52.51496980,
            longitude      : 13.39258080,
            latitudeDelta  : 0.1,
            longitudeDelta : 0.1,
        },
        annotations : [mapAnnotation],
    });

    // add the map view to the google maps wrapper view
    $.vGoogleMaps.add(mapView);

} catch(ex) {
    console.error(ex);
}

As you can see, the code is not very complex and very similar to the one defined in the documentation. However, I didn't touch this code ever and the only thing I did, was updating my dependencies (updated the TiMap plugin from v3.0.1 to v3.1.0). Since then, for some of our users the app crashes sometimes with the error message mentioned above. Again, I am unable to reproduce it and the error message doesn't make much sense to me.

Best,
Tom
