New Request - Update View after location has been retrieved

[hyarlagadda]

I am trying to update the view as soon as the location has been retrieved. I added the below code in viewDidLoad method of my UIViewController.

[ [LocationShareModel sharedModel] addObserver:self forKeyPath:@"myLocationArray" options:NSKeyValueObservingOptionNew context:nil];

and added below code in my UIViewController for receiving the update.

-(void) observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {

if ( [keyPath isEqualToString:@"myLocationArray"] ) {
    NSLog(@"changedValues: %@", change);
    NSLog(@"Received value");
}

}

The observerValueForkeyPath is not being called.

Highly appreciate your help in this.
