SJOPaperboy

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.

On iOS7 and above, an addition setting is displayed if you have the UIBackgroundMode fetch enabled in your Info.plist. This allows you to optionally run the new style background updates depending on the user's preference, as well as still having access to the old-style location based updates.

Setup

If you are using CocoaPods, just add the following to your Podspec:

pod 'SJOPaperboy', '~> 2.0.0'

Setup (without CocoaPods)

Copy the following files to your Xcode project:

IPInsetLabel.h
IPInsetLabel.m
SJOPaperboyLocationManager.h
SJOPaperboyLocationManager.m
SJOPaperboyViewController.h
SJOPaperboyViewController.m

Usage

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.

Dependancies

SJOPaperboy requires the CoreLocation (for determining user location) and AddressBookUI (for formatting address strings) frameworks. If you aren't using CocoaPods make sure to add them to 'Link Binary with Libraries' under 'Build Phases' of your target.
