Core Location Notifier

RHCoreLocationNotifier generates and dispatches NSNotifications whenever a CLLocationManager in your application updates its delegate with new location information.

This is especially useful if you only wish to piggyback on updates generated by other location updating code.

How does it work?

RHCoreLocationNotifier works by injected a proxy class between CLLocationManager and its delegate, invisibly forwarding all delegate method calls onwards, while at the same time siphoning any CLLocation objects 'from the wire' as they pass through.

RHCoreLocationNotifierLocationChangedNotifications are dispatched for all initialized CLLocationManager instances automatically, and there is no setup required.

Usage

Using RHCoreLocationNotifier is super simple, just register for notifications and you are good to go.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(_locationUpdatedNotification:) name:RHCoreLocationNotifierLocationChangedNotification object:nil];
...


-(void)_locationUpdatedNotification:(NSNotification *)notification{
    dispatch_async(dispatch_get_main_queue(), ^{
        NSArray *locations = [notification.userInfo objectForKey:RHCoreLocationNotifierAllLocationsKey];
        //do your thing
    });
}

Version Support

RHCoreLocationNotifier has been tested on iOS 7 and OS X 10.9 and it should support all currently used system architectures (including arm64). It should also work fine with older OS versions.
