CLLocationCoordinate2D *coords = malloc(coordinateCount * sizeof(CLLocationCoordinate2D));
for(size_t i = 0; i < coordinateCount; ++i)  
{
    coords[i].latitude = latitudes[i];
    coords[i].longitude = longitudes[i];
}

// ... Use the array ...

free(coords);

  • Can you edit your question to include your implementation or at least provide the exception message, because I just ran this code and it worked fine. – warrenm Feb 07 '13 at 18:01
  • Maybe he would prefer object approach using `NSArray`. – Tricertops Feb 07 '13 at 20:57
  • If the intent is to draw a polyline with MapKit, the end result should be a C array of `CLLocationCoordinate2D`, as that's what the API calls for. Hopefully we'll get clarification from the asker on the type of the original arrays. – warrenm Feb 07 '13 at 21:42
