Question

i use this code to get gps data

- (void)locationUpdate:(CLLocation *)location {
    locLabel.text = [location description];
}

the result look like this

<+38.76856432, +11.99454301> +/- 100.00m (speed ……)

when i trie this i have an error,

- (void)locationUpdate:(CLLocation *)location {
    locLabel.text = [location altitude];}

error

Assigng to “NSString *” from incompatible type CLLocationDistance
(aka double)

i want to get longitude too

Answer 1

You should be able to get latitude and longitude separately from location.coordinate.latitude and location.coordinate.longitude.

The altitude you are receiving may be invalid. Check the value in location.verticalAccuracy. Per the documentation, “A negative value indicates that the altitude value is invalid.” Same goes for location.horizontalAccuracy to make sure the latitude and longitude values in location.coordinate are valid.
