How can i use a variable created in a objective c Void function?

Question

Im trying to get the lat and long values generated in a void function and use them within another function. Any help grateful.

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
 float latDeg = newLocation.coordinate.latitude;
 NSLog(@"Lat: %g", latDeg);

 float longDeg = newLocation.coordinate.longitude;
 NSLog(@"Lat: %g", longDeg);
}

I want to use the latDeg and longDeg variables.

Answer 1

Declare latDeg and longDeg as instance variables in your class. Declaring properties for the instance variables and using them for every access of the variable is optional, but recommended.

Answer 2

If you want to reuse them in the same class, you can just declare them after implementation of you class. For example `@implementation LocationClass float latDeg; float longDeg

• (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { latDeg = newLocation.coordinate.latitude; NSLog(@"Lat: %g", latDeg);

  longDeg = newLocation.coordinate.longitude; NSLog(@"Lat: %g", longDeg); } ` that's enough. Or you can declare them in you AppDelegater and then use them like:

  YourAppDelegate delegate; delegate = (YourAppDelegate) [[UIApplication sharedApplication] delegate]; float currVar = [delegate->longDeg];
