GPS location timestamp issue

[lionkingden]

isn't this code enough to get the current location using the locationManager. I try to do it checking the timestamp and using a loop

The reason i ask is because i am getting 0000.0 as ltitude and longitudes and cannot figure out why

// initialization of CLLocationManager

CLLocationManager *locationManager = [[CLLocationManager alloc] init];

locationManager.delegate = self;
locationManager.distanceFilter = 1000; // 1 kilometer
locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
[locationManager startUpdatingLocation];

//use the timestamp to get the latest location

NSDate* eventDate = locationManager.location.timestamp;
NSTimeInterval howRecent;
do{

howRecent = [eventDate timeIntervalSinceNow];
}
while(abs(howRecent) > 5.0);

//stop gps after getting the recent location

[locationManager stopUpdatingLocation];

float lat= locationManager.location.coordinate.latitude+0.0;
float lon= locationManager.location.coordinate.latitude+0.0;

//create the HTML for the webpage

NSString *HTMLData = [NSString stringWithFormat: @"latitude %f longitude %f at %c",lat, lon, howRecent];

[webView loadHTMLString:HTMLData baseURL:nil];

You haven't supplied a delegate method for the CLLocationManager to call. Since the delegate method is optional, CLLocationManager just goes merrily on it's way.

The code starting with // Use the timestamp... needs to be moved to your delegate.
