MapKit and CoreLocation for Cappuccino

A port of Cocoa's MapKit and CoreLocation frameworks to Cappuccino. This is tested against Cappuccino master, but should potentially work on 0.8 and above.

Status

There is still a lot to do. I haven't messed with this code in a bit and won't have time to for a little bit longer. I'm not entirely sure what state it's in, but it should be mostly usable.

Installation

The framework will not include Google Maps for you. Simply add this to your index.html files: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>

Place the entire CappuGeo folder in your Frameworks folder, or anywhere else that is included in OBJJ_INCLUDE_PATHS.

Use: @import <CappuGeo/CoreLocation.j> and/or @import <CappuGeo/MapKit.j> when you want to access the classes.

Note: @import <CappuGeo/CappuGeo.j> will import both frameworks.

CoreLocation

The singleton CLLocationManager will attempt to geolocate the user. If they are using a browser supporting the new geolocation API, it will be used, otherwise falling back to unreliable IP methods. You can force one method or the other using -setDesiredAccuracy:. After you call -startUpdatingLocation, the CLLocationManager will begin firing CLLocationManagerDidUpdateNotification notifications. Whenever this event happens, you can query the location manager for -location, which will return the CLLocation object.

- (id)init
{
	self = [super init];
	
	if (self)
	{
		[[CPNotificationCenter defaultCenter] addObserver:self selector:@selector(locationDidChange:) name:CLLocationManagerDidUpdateNotification object:nil];
		[[CLLocationManager sharedManager] startUpdatingLocation];
	}
	
	return self;
}

- (void)locationDidChange:(CPNotification)aNotification
{
	var location = [[CLLocationManager sharedManager] location];
	
	// Let's get some geocoded results
	[[CPNotificationCenter defaultCenter] addObserver:self selector:@selector(locationDidGeocode:) name:CLLocationDidFindPlacemarkNotification object:location];
	[location geocode];
}

- (void)locationDidGeocode:(CPNotification)aNotification
{
	var location = [aNotification object],
		placemark = [location placemark];
	
	alert([CPString stringWithFormat:@"How's the weather in %@?", [placemark canonical]]);
}

MapKit

MapKit is much more complex than CoreLocation. I would recommend seeing Apple's documentation.

Note: This version of MapKit has not been updated with the version of MapKit in the iOS SDK 4.0. The new classes that were added are not present. There are also a bit of additional things to make this work in Cappuccino.
