Delegate use with CLLocationManagerDelegate not working objective c - ios

Question

I have create a custom delegate with CLLocationManagerDelegate when i call the delegate methods inside CLLocationManagerDelegate delegates are not working properly. i think the way i create the delegate was wrong can someone tell me what i have done wrong ?
.h file
#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>
#import <UIKit/UIKit.h>
#protocol iBeaconDeligate<NSObject>
#required
-(void)getArray:(NSArray *)beaconArray;
#end
#interface iBeaconDeligate : NSObject <CLLocationManagerDelegate>
#property (strong, nonatomic) CLLocationManager *locationManager;
#property CLProximity lastProximity;
-(void) initiBeaconDeligate;
#end
this is .m file
#import "iBeaconDeligate.h"
#implementation iBeaconDeligate
-(void) initiBeaconDeligate
{
NSUUID *beaconUUID = [[NSUUID alloc] initWithUUIDString:
#"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"];
NSString *beaconIdentifier = #"iBeaconModules.us";
CLBeaconRegion *beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:
beaconUUID identifier:beaconIdentifier];
self.locationManager = [[CLLocationManager alloc] init];
//[self.locationManager requestWhenInUseAuthorization];
//[self.locationManager requestAlwaysAuthorization];
// New iOS 8 request for Always Authorization, required for iBeacons to work!
if([self.locationManager respondsToSelector:#selector(requestAlwaysAuthorization)]) {
[self.locationManager requestAlwaysAuthorization];
}
self.locationManager.delegate = self;
self.locationManager.pausesLocationUpdatesAutomatically = NO;
[self.locationManager startMonitoringForRegion:beaconRegion];
[self.locationManager startRangingBeaconsInRegion:beaconRegion];
[self.locationManager startUpdatingLocation];
}
-(void)sendLocalNotificationWithMessage:(NSString*)message {
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60];
notification.alertBody = message;
notification.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:
(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
NSString *message = #"";
if(beacons.count > 0) {
CLBeacon *nearestBeacon = beacons.firstObject;
if(nearestBeacon.proximity == self.lastProximity ||
nearestBeacon.proximity == CLProximityUnknown) {
return;
}
self.lastProximity = nearestBeacon.proximity;
switch(nearestBeacon.proximity) {
case CLProximityFar:
message = #"You are far away from the beacon";
break;
case CLProximityNear:
message = #"You are near the beacon";
break;
case CLProximityImmediate:
message = #"You are in the immediate proximity of the beacon";
break;
case CLProximityUnknown:
return;
}
} else {
message = #"No beacons are nearby";
}
[self performSelector:#selector(getArray:) withObject:beacons];
NSLog(#"%#", message);
[self sendLocalNotificationWithMessage:message];
}
-(void)locationManager:(CLLocationManager *)manager
didEnterRegion:(CLRegion *)region {
[manager startRangingBeaconsInRegion:(CLBeaconRegion*)region];
[self.locationManager startUpdatingLocation];
NSLog(#"You entered the region.");
[self sendLocalNotificationWithMessage:#"You entered the region."];
}
-(void)locationManager:(CLLocationManager *)manager
didExitRegion:(CLRegion *)region {
[manager stopRangingBeaconsInRegion:(CLBeaconRegion*)region];
[self.locationManager stopUpdatingLocation];
NSLog(#"You exited the region.");
[self sendLocalNotificationWithMessage:#"You exited the region."];
}
#end
this is how i called it in my controller class
.h
#interface HomeViewController : UIViewController<iBeaconDeligate>
.m
iBeaconDeligate *sampleProtocol = [[iBeaconDeligate alloc]init];
[sampleProtocol initiBeaconDeligate];
the problem was methodes that invoke automatically in CLLocationManagerDelegate are not calling in my custom delegate

Answer 1

As sampleProtocol is a local variable inside the method, it will be deallocated when the method exits.
You should create a (strong) #property to store this object to ensure it is retained.
