Delegate methods not being called, can't see why - ios

Question

FIXED: I was creating my CLLocationManager in the viewDidLoad method, so it was being cleaned by ARC almost immediately. I changed my instance to be a class instance instead of method instance and the problem is solved.
I have a class, an NSObject, which I'm using to control the entering and exiting of beacon regions.
It's implementation is here:
#import "dcBeaconManager.h"
#implementation dcBeaconManager
-(id)init
{
self = [super init];
if (self != nil){}
return self;
}
bool testRanging = true;
bool firstRegionEntered = true;
- (void)initBeaconManager {
NSLog(#"initBeaconManager called");
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
NSUUID *uuid = [[NSUUID alloc]initWithUUIDString:#"B9407F30-F5F8-466E-AFF9-25556B57FE6D"];
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:#"digiConsRegion"];
[self.locationManager startMonitoringForRegion:self.beaconRegion];
}
- (void)stopBeaconManager {
[self.locationManager stopMonitoringForRegion:self.beaconRegion];
}
- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region {
NSLog(#"Started looking for regions");
[self.locationManager requestStateForRegion:self.beaconRegion];
}
- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
NSLog(#"Region discovered");
if (firstRegionEntered) {
NSLog(#"First time in region");
firstRegionEntered = false;
}
[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSLog(#"Region left");
[self.locationManager stopRangingBeaconsInRegion:self.beaconRegion];
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.alertBody = #"We hope you enjoyed the event, thank you for coming.";
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
}
- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
NSLog(#"locationManager initiated");
CLBeacon *beacon = [[CLBeacon alloc] init];
beacon = [beacons lastObject];
//Store some information about this beacon
NSNumber *currentBeaconMajor = beacon.major; //it's major (group) number
NSNumber *currentBeaconMinor = beacon.minor; //it's minor (individual) number
if (([currentBeaconMinor floatValue] == 59204) && ([currentBeaconMajor floatValue] == 33995) && (beacon.proximity == CLProximityNear)) {
NSLog(#"Mint discovered");
[[NSNotificationCenter defaultCenter] postNotificationName:#"didLocateMint" object:nil];
} else if (([currentBeaconMinor floatValue] == 7451) && ([currentBeaconMajor floatValue] == 63627) && (beacon.proximity == CLProximityNear)) {
NSLog(#"Blue discovered");
[[NSNotificationCenter defaultCenter] postNotificationName:#"didLocateBlue" object:nil];
} else if (([currentBeaconMinor floatValue] == 51657) && ([currentBeaconMajor floatValue] == 26976) && (beacon.proximity == CLProximityNear)) {
NSLog(#"Purple discovered");
[[NSNotificationCenter defaultCenter] postNotificationName:#"didLocatePurple" object:nil];
}
}
- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region {
if (testRanging) {
NSLog(#"Testing: forced ranging");
if ([region isEqual:self.beaconRegion] && state == CLRegionStateInside) {
[_locationManager startRangingBeaconsInRegion:(CLBeaconRegion *)region];
}
}
}
#end
Here's the header:
#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>
#import <CoreBluetooth/CoreBluetooth.h>
#interface dcBeaconManager : NSObject <CLLocationManagerDelegate>
//properties
#property (strong, nonatomic) CLBeaconRegion *beaconRegion; //used to define which beacons we are looking for
#property (strong, nonatomic) CLLocationManager *locationManager; //set up location services and allow beacons to be found
//methods
- (void)initBeaconManager;
- (void)stopBeaconManager;
#end
Now, this code has worked fine before when included in the main view controller, but I'm trying to get better at OOP in Obj-C. The logs show the object is created and the main initBeaconManager is called, but from there is just stops. I cannot figure out why. Any thoughts?
Cheers.

Answer 1

I'm not sure this help but can you replace this line:
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:#"digiConsRegion"];
with that one:
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid major:1 minor:2 identifier:#"digiConsRegion"];
self.beaconRegion.notifyOnEntry = entry;
self.beaconRegion.notifyOnExit = exit;
self.beaconRegion.notifyEntryStateOnDisplay = YES;
I believe you need to provide major and minor values for bacon region.

I was creating my CLLocationManager in my viewDidLoad method, and ARC was killing it off almost immediately. Moving it to be a class instance instead of a method instance fixed the problem.
