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:
NSUInteger count = [self.locations count];
CLLocationCoordinate2D coordinates[count];
for (NSInteger i = 0; i < count; i++) {
coordinates[i] = [(CLLocation *)self.locations[i] coordinate];
NSValue *locationValue = [NSValue valueWithMKCoordinate:coordinates[i]];
[_locationsArray addObject:locationValue];
NSLog(@"location = %@", _locationsArray);
}
However the NSLog
displays that the array is filled with (Null) values. I'm not sure where I have gone wrong here, an someone point me in the right direction?
I didn't see any need in coordinates
array. 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);
}
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
Try:
NSValue *locationValue = [NSValue valueWithBytes:&coordinates[i] objCType:@encode(CLLocationCoordinate2D)];
It can be that you didn't initialize your array. That's why it's nil when you log it.
_locationsArray = [[NSMutableArray alloc] init];
