Overview

A marker is a balloon-shaped annotation that contains a glyph or text. On the map, the marker appears when its coordinate is in view.

The following example shows a customized marker that specifies a color for the balloon background and the glyph, and provides custom glyph images. Color properties accept either a color name, here “brown” and “green”, or the equivalent hexadecimal color value such as “#A52A2A” and “#008000”, respectively. Or, you can use a specific color that matches your app’s specific design. For more information on standardized colors, see the CSS working group’s list of common color names and values.

const portland = new mapkit.Coordinate(45.514956, -122.679187);  // Portland City Hall, Portland, OR
const customMarker = new MarkerAnnotation(portland, {
    color: "green",
    glyphColor: "brown",
    glyphImage: { 1: "glyphImage.png" },
    selectedGlyphImage: { 1: "detailedIcon.png", 2: "detailedIcon_2x.png", 3: "detailedIcon_3x.png" }
});

The following example shows a marker annotation with a custom callout implemented by the callout delegate. In this example, the annotation is a dot when selected because selectedGlyphImage isn’t used.

const calloutDelegate = {
    calloutRightAccessoryForAnnotation: function() {
        const accessoryViewRight = document.createElement("a");
        accessoryViewRight.className = "right-accessory-view";
        accessoryViewRight.href = "https://www.nps.gov/stli/index.htm";
        accessoryViewRight.target = "_blank";
        accessoryViewRight.appendChild(document.createTextNode("ⓘ"));

        return accessoryViewRight;
    }
};

const annotation = new mapkit.MarkerAnnotation(new mapkit.Coordinate(40.6892, -74.0445), {
    title: "Title",
    subtitle: "Subtitle",
    callout: calloutDelegate
});
