I'm currently developing my first CoreLocation-based app and I have a problem with the CLLocationManager not calling delegate methods. Here's the class I'm using:
//
// LocationGetter.h
// whatsunderme
//
// Created by Tobias Timpe on 16.06.12.
// Copyright (c) 2012 tobisoft. All rights reserved.
//
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@protocol LocationGetterDelegate
@required
- (void) newPhysicalLocation:(CLLocation *)location;
@end
@interface LocationGetter : NSObject <CLLocationManagerDelegate> {
CLLocationManager *locationManager;
id delegate;
}
- (void)startUpdates;
@property (nonatomic, retain) CLLocationManager *locationManager;
@property (nonatomic, retain) id delegate;
@end
//
// LocationGetter.m
// whatsunderme
//

//
#import "LocationGetter.h"
@implementation LocationGetter
@synthesize locationManager, delegate;
BOOL didUpdate = NO;
- (void)startUpdates {
if (self.locationManager == nil) {
self.locationManager = [[CLLocationManager alloc] init];
}
self.locationManager.delegate = self;
NSLog(@"Starting Location Updates");
locationManager.distanceFilter = 100;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[self.locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
NSLog(@"Error");
}
// Delegate method from the CLLocationManagerDelegate protocol.
- (void)locationManager:(CLLocationManager *)manage didUpdateToLocation:(CLLocation *)
newLocation fromLocation:(CLLocation *)oldLocation {
NSLog(@"new Location found");
didUpdate = YES;
// Disable future updates to save power.
[self.locationManager stopUpdatingLocation];
[self.delegate newPhysicalLocation:newLocation];
}
@end
Neither the didUpdateToLocation nor the didFailWithError methods are getting called. I don't know why.
Hope you can help me with this since I've been trying to figure out what the problem is for 2 hours.

Use my code, it should work for you...
First ensure you are using the protocol by adding the following, for example to your AppDelegate or whichever controller you want CoreLocation to work in...
Create some properties, I also use a custom method but you don't have too...
Then in your implementation file call the custom method to start CL
Below is the code to my custom method.
