Setting up background detection is pretty automatic in iOS so long as you do it in your AppDelegate and receive callbacks in that class:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    _locationManager = [[CLLocationManager alloc] init];
    _locationManager.delegate = self;
    CLBeaconRegion *region;

    region = [[CLBeaconRegion alloc] initWithProximityUUID:[[NSUUID alloc] initWithUUIDString:@"2F234454-CF6D-4A0F-ADF2-F4911BA9FFA6"] major: 1 minor: 1 identifier: @"region1"];
    region.notifyEntryStateOnDisplay = YES;
    [_locationManager startMonitoringForRegion:region];
    [_locationManager startRangingBeaconsInRegion:region];

    return YES;
}
