Question

I have a this function to grab the lat and long in my app delegate, and it’s working fine:

- (void)newPhysicalLocation:(CLLocation *)location {

    // Store for later use
    self.lastKnownLocation = location;

    // Remove spinner from view
    for (UIView *v in [self.viewController.view subviews])
    {
        if ([v class] == [UIActivityIndicatorView class])
        {
            [v removeFromSuperview];
            break;
        }
    }

    // Alert user
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Location Found" message:[NSString stringWithFormat:@"Found physical location.  %f %f", self.lastKnownLocation.coordinate.latitude, self.lastKnownLocation.coordinate.longitude] delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
    [alert show];
    [alert release];  

    currentLatitude = (self.lastKnownLocation.coordinate.latitude);
    NSLog(@"current latitude: %f",self.lastKnownLocation.coordinate.latitude);


    currentLongitude = (self.lastKnownLocation.coordinate.longitude);
    NSLog(@"current longitude: %f",currentLongitude);
}

However, I’m trying to send the currentLatitude and currentLongitude values to the top of the app delegate in the didFinishLaunchingWithOptions section. I’m trying to do this so I can pass those values to another viewController in which I have set up:

MyAppDelegate *appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];

Can I send the currentLatitude and currentLongitude values to the didFinishLaunchingWithOptions section?

Answer 1

From what I understood from your question, you want to pass those coordinate values to another view controller. If thats the case u can make the currentLatitude and currentLongitude as class variables of the app delegate. Then when u call this function in applicationDidFinishLaunchingWithOptions: you can assign the values to these class variables. Then u can access these variables anywhere through an instance of the app delegate.

Note: You have to synthesize the variables if u want to access them outside the class.

Hope this helps
