UIApplicationDelegate methods not being called - iphone

Question

I am trying to create a plugin for region monitoring. Region Monitoring is starting fine but the function didfinishlaunching and didrecievelocalnotification are not being evoked. I am not sure why this is happening.
regionMonitoring.h
#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>
#interface RegionMonitoringPlugin : NSObject <UIApplicationDelegate,CLLocationManagerDelegate>
{
CLLocationManager *locationManager;
}
-(void)enterRegionNotify;
-(void)leaveRegionNotify;
-(void)startMonitor:(float)latitude longitude:(float)longitude radius:(float)raduis;
#end
regionMonitoring.mm
#import "RegionMonitoringPlugin.h"
#implementation RegionMonitoringPlugin
- (id) init
{
//if ( init == [super init]){
if (locationManager==nil){
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager setDistanceFilter:kCLDistanceFilterNone];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
}
return self;
}
-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
{
[self enterRegionNotify];
}
-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
{
[self leaveRegionNotify];
}
- (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)regionwithError:(NSError *)error
{
NSLog(#"Location error %#, %#", error, #"Fill in the reason here");
}
-(void)leaveRegionNotify
{
NSLog(#"Starting region monitoring - check point 3");
UILocalNotification *note = [[UILocalNotification alloc] init];
note.alertBody= #"Region Left"; // ToAsk: What should be displayed
note.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] presentLocalNotificationNow:note];
[note release];
}
-(void)enterRegionNotify
{
UILocalNotification *note = [[UILocalNotification alloc] init];
note.alertBody= #"Region Left"; //ToAsk: what should be displayed ?
note.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] presentLocalNotificationNow:note];
[note release];
}
-(void)startMonitor:(float)latitude longitude:(float)longitude radius:(float)radius
{
NSLog(#"Starting region monitoring - check point 2");
[self leaveRegionNotify];
CLLocationCoordinate2D home;
home.latitude = latitude;
home.longitude = longitude;
CLRegion* region = [[CLRegion alloc] initCircularRegionWithCenter:home radius:radius identifier:#"region"];
[locationManager startMonitoringForRegion:region desiredAccuracy:kCLLocationAccuracyBest];
[region release];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
NSLog(#"Starting region monitoring - checkpoint 4");
if ([UIApplication sharedApplication].applicationState == UIApplicationStateActive) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Region Monitor Notification" message:notification.alertBody delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
[alertView release];
}
}
- (BOOL)application:(UIApplication *) application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSLog(#"Test");
return TRUE;
}
#end
extern "C" {
static RegionMonitoringPlugin *regionMonitor;
// Unity callable function to start region monitoring
BOOL _startRegionMonitoring(float m_latitude,float m_longitude, float m_radius)
{
NSLog(#"Starting region monitoring");
if (![CLLocationManager regionMonitoringAvailable] || ![CLLocationManager regionMonitoringEnabled] )
return NO;
if (regionMonitor == nil){
regionMonitor = [[RegionMonitoringPlugin alloc] init] ;
}
[regionMonitor startMonitor:m_latitude longitude:m_longitude radius:m_radius];
return YES;
}
}
Unity Code for plugin : RegionMonitorMediater.h
using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
public class RegionMonitoringMediator {
/*Interface to native implementation */
[DllImport ("__Internal")]
private static extern bool _startRegionMonitoring (float m_latitude,float m_longitude, float m_radius);
public static bool startRegionMonitoring (float latitude,float longitude, float radius)
{
/*Call plugin only when running on real device*/
if (Application.platform != RuntimePlatform.OSXEditor)
return _startRegionMonitoring ( latitude , longitude , radius);
else return false;
}
}
Calling region monitor
OnPress event I do
bool startedRM = RegionMonitoringMediator.startRegionMonitoring(77.0f,28.0f,10.0f);

Answer 1

There is only one UIApplicationDelegate allowed per app. When Unity3D builds your application for iPhone player a class AppController is generated which acts as interface.
This class is the place for inserting your code to call RegionMonitoringPlugin.

Answer 2

init should include a call to super at its start:
- (id) init
{
if (self = [super init])
{
// initialize everything else
}
return self;
}
note that we used assignment (=) operator, and not comparison (==) operator.
