Converting CLLocationCoordinates2D into an NSValue

Question

I\'m simply trying to convert CLLocationCoordinates into an NSValue to be used in an array brought back later in my app. Here is my code:

Answer 1

It can be that you didn't initialize your array. That's why it's nil when you log it.

_locationsArray = [[NSMutableArray alloc] init];

Answer 2

Try:

NSValue *locationValue = [NSValue valueWithBytes:&coordinates[i] objCType:@encode(CLLocationCoordinate2D)];

Answer 3

Hi you can convert the CLLocationCoordinates2D into an NSValue by doing like below but have you check the coordinate contains any value or not once.

NSValue *value = [NSValue valueWithMKCoordinate:coordinate];

Thanks

Answer 4

I didn't see any need in coordinatesarray. And you probably didn't initialised it. Try:

_locationsArray = [NSMutableArray array];
for (CLLocation *location in self.locations) {
    NSValue *locationValue = [NSValue valueWithMKCoordinate: location.coordinate];
    [_locationsArray addObject:locationValue];
    NSLog(@"location = %@", _locationsArray);
}
