An easy to use library that lets you implement background updates in your app that run whenever the user enters or exits a specified location.
SJOPaperboy requires the CoreLocation (for determining user location) and AddressBookUI
(for formatting address strings) frameworks. Make sure to add them to 'Link Binary with Libraries'
under 'Build Phases' of your target.
Copy the following files to your Xcode project:
IPInsetLabel.h
IPInsetLabel.m
SJOPaperboyLocationManager.h
SJOPaperboyLocationManager.m
SJOPaperboyViewController.h
SJOPaperboyViewController.m
Have your AppDelegate class have a CLLocationManager as a property.
@property (strong, nonatomic) CLLocationManager *paperboyLocationManager;
Then, in application:didFinishLaunchingWithOptions: add the following:
self.paperboyLocationManager = [SJOPaperboyLocationManager sharedLocationManager];
[[SJOPaperboyLocationManager sharedInstance] setLocationChangedBlock:^{
//Perform your background updates here.
}];
To allow users to add geofencing locations, display SJOPaperboyViewController:
SJOPaperboyViewController* paperboyViewController = [[SJOPaperboyViewController alloc] init];
You can customise elements of the view controller by editing Paperboy.strings.
See the included example project for more implementation details.

Inspired by the feature in News.me, Digg, and Instapaper (plus many others).
