As shown in Figure 8-4, add a label in your storyboard scene, after the time label. Be sure to connect the property via the Connection Inspector in Interface Builder.

Figure 8-4.Adding a label to the storyboard

To perform the weather look-up, you need to provide Weather Underground with a zip code. In the awakeWithContext() method of the class, add a geocoder to convert the location to a place-mark with human-readable attributes (Listing 8-22).

Listing 8-22.Performing a Weather Look-up (LocationInterfaceController.swift)

override func awakeWithContext(context: AnyObject?) {

super.awakeWithContext(context)

// Configure interface objects here.

// Configure interface objects here.

if let locationDict = context as? Dictionary<String, AnyObject> {

if let latitude = locationDict["Latitude"] as? Double {

if let longitude = locationDict["Longitude"] as? Double {

let location = CLLocation(latitude: latitude, longitude: longitude)

let prettyLocation = String(format: "%.2f, %.2f", location.coordinate.latitude, location.coordinate.longitude)

coordinatesLabel?.setText(prettyLocation)

currentLocation = CLLocation(latitude: latitude, longitude: longitude)

locationMap?.addAnnotation(location.coordinate, withPinColor: WKInterfaceMapPinColor.Red)

let mapRegion = MKCoordinateRegionMake(location.coordinate, MKCoordinateSpanMake(0.1, 0.1))

locationMap?.setRegion(mapRegion)

geocodeLocation()

}

}

if let timestamp = locationDict["Timestamp"] as? NSDate {

...

}

}

}
