Getting a Key value coding compliant error message

Question

I am actually designing a simple app to make use of the core location to get the location details and at the same time, displaying the latitude and longitude. But when I run it, I get an error message as below:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key forLatitude.'

I have synthesised the properties too. I still do not know the exact reason as to why it is throwing up an error !

rajViewController.h

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@interface rajViewController : UIViewController <CLLocationManagerDelegate>


@property (weak, nonatomic) IBOutlet UILabel *latitudeLabel;

@property (weak, nonatomic) IBOutlet UILabel *longitudeLabel;
@property (weak, nonatomic) IBOutlet UILabel *addressLabel;
- (IBAction)getCurrentLocation:(id)sender;

@end

rajViewController.m

@interface rajViewController (){
    CLLocationManager *locationManager;
    CLGeocoder *geo;
    CLPlacemark *placemark;
}


@end

@implementation rajViewController
//@synthesize placemark;
@synthesize latitudeLabel;
@synthesize longitudeLabel;

.
.
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *newPlace = [[CLLocation alloc]init];
    newPlace = [locations lastObject];
    NSLog(@"the latitude is : %f",newPlace.coordinate.latitude);
    if (newPlace!=nil){
        self.latitudeLabel.text = [NSString stringWithFormat:@"%f", newPlace.coordinate.latitude];
        self.longitudeLabel.text = [NSString stringWithFormat:@"%f",newPlace.coordinate.longitude];
    }

}

Any help would be much appreciated.

Thanks and Regards, Raj.

hi Raj the problem may be before initializing ur NSDictionary ur setting value for somekey in dictionary first check if it not create just create it @Raj0689 — Sugan S, Apr 08 '13 at 13:11
Hi sugan ! Sorry.. But can you be little specific.. Since I am new to objective-C :( — Raj0689, Apr 08 '13 at 13:18
hi raj you are trying to set value for key in dictionary that is not created just put NSLog before setting value to dict if it is null(dict).Just do dictname=[[NSMutableDictionary alloc]init] k.let me know if u not get — Sugan S, Apr 09 '13 at 04:26

Check your nib to see if you have some connection to outlet called forLatitude. It's not a core location problem, this is an outlet connection problem
